Seed starting media is what is used to, you guessed it, start your seeds in! Why does starting seeds require its own media? Why not just use some good garden soil or well-aged compost? What is the difference anyway? These are valid questions that all too often go unanswered, leading to disappointment, frustration and failure for the home gardener trying to get a jump on the season by starting their own seeds for transplants.
The first thing to recognize is that starting seeds inside and growing them into transplants is much different than what happens in the garden with direct seeding. Growing inside has advantages and challenges that simply do not exist in the garden, with its own rules. Temperature can be controlled and modified inside, as well as lighting to ensure success. Humidity and soil moisture levels are other things that can and need to be controlled to get the young seedling to the strapping transplant stage. A good seed starting mix provides a sterile environment free of fungus, mold or viruses, good drainage to allow better soil moisture management, and minimizes nutrient leaching from the young root systems. These are all things that are just not possible to control outside, forcing the gardener to wait until conditions are right before sowing the seeds directly into the soil and hoping that the weather cooperates. Thus the entire reason to start your own seeds inside, in a nutshell! You have control- control of the choice of what to plant, what varieties of tomatoes, peppers and such that are not available at the local garden center or nursery, and control of all of the variables that will grow a healthy, sturdy and productive member of the garden.
It all starts with the choice of the right seed starting media or mix. Get it right and you are well on your way to success. Get it wrong and you could have some challenges that slow you down. Luckily, it is not difficult at all! When you visit your local garden center, home improvement store or local market, it might be confusing on which growing media to buy. For the beginning gardener, buying seed starting media is the best and safest choice for success. This is not the time to overthink or overcomplicate things. Find the simplest, most successful way possible and stick with that method. You will have plenty of time to experiment with different approaches and systems once the seedlings are transplanted into your garden. What you need for starting seeds is a dead-simple, easily repeatable, always successful method to get the seeds up and healthy. As you gain experience and knowledge you can do some experimenting to see what “recipes” or hand-made mixes work well for you. Below we will tell you more about each type.
Perlite
Perlite– An amorphous volcanic glass expanded to about 13 times its original volume by heating to 1,800F; it is used as a soil additive to help prevent water loss and soil compaction and is white in color. Perlite provides aeration and optimum moisture retention for superior seedling growth. It is sterile and has a pH of approximately 7, or neutral. Used to condition garden soil to improve aeration and drainage.
Vermiculite
Vermiculite– A mica mineral expanded by heating it to 1,400F; used as part of peat-lite mixes. Similar to perlite it is lightweight, highly absorbent, increases aeration and moisture retention, and minimizes fertilizer leaching.
Peat Moss
Peat moss– Organic material used in many soil mixes to grow plants in. It comes from Peat bogs, which are natural deposits of peat moss. Peat Bogs are found in very Northern Countries such as Canada. This is a finite resource.
Peat pots– Pots made from compressed peat moss and paper.
Rock Wool
Rock Wool– A growing media is an inorganic product that is made by melting together at a very high temperature a mixture of basalt, coke and limestone into lava which is blown into a large spinning chamber which pulls the lava into fibers like “cotton candy”. Rock wool fibers hold a lot of water; this medium is usually used in greenhouse production.
Compressed Coconut Coir
Coir– A natural fiber extracted from the husk of coconut and has a large capacity to absorb water and still provide aeration. It is a strongly recommended substitute for sphagnum (Peat) moss because it is free of bacterial and fungal spores, and produces good results without the environmental damage caused by peat mining.
Wetting agent– Material added to water to reduce the surface tension and make the water wetter.
Seed Starting Mix
Many common Seed Starting Potting Mixes will contain peat moss, perlite, a fertilizer and a wetting agent. There are many different brands of Seed Starting Mixes on the market or you can create your own. Take a look at our Seed Starting Department for ideas and tools to help you get the best out of your seed starting efforts.
Here are a couple of hand-made mixes from The New Seed Starters Handbook by Nancy Bubel. Nancy was the author of many books at Rodale and the author of the Storey Publication Grow Super Salad Greens.
Good and Simple Potting Soil
One part finished compost
One part vermiculite
Home-Style Potting Mix
One part finished compost
One part either loose garden soil or potting soil
One part sharp sand, perlite or vermiculite or a mixture of all three.
If you are a beginner it might be easiest to buy a bagged mix or a tray with coir pellets to start with. After a little experience you will find what works best for you.
A personal favorite is using a soil blocker and creating your own custom mix based on Eliot Coleman’s methods. Chapter 14 of The New Organic Grower covers the complete use of soil blocks and blocking mixes. If you start a lot of starts or are a larger grower this method might be worth exploring.
With an understanding of the importance of a good seed starting mix, and the ingredients commonly available, you have the tools needed to have a successful start to your seedlings, a more productive garden and great home grown food. We will be continuing the planning, seed starting and planting series with some seed starting basics, tools and experiences that have helped us have a high success rate.

French sorrel is known as “lemonade leaf” and has been prized for its nutritional and culinary qualities for centuries. In many climates it will nativize.
When it comes to starting their own heirloom seeds, home gardeners seem to be in two distinct camps- those that are really positive about the process and results, and those that aren’t. The folks that aren’t too excited about starting their own seeds usually have a good reason- they’ve had some failures with die-off and had to scramble to buy starts at the local garden center and wound up with something that they didn’t really want. Others haven’t tried their own starts, but feel that it is complicated or difficult. There are some very compelling reasons to start your own seedlings, but there are some challenges to overcome as well. We will look at several items to consider in making the decision of whether or not to do your own starts, along with some tips to get you started successfully.
Why start your own seeds? What advantages/disadvantages are there?
You have a much greater range of choice on what to grow as you are not limited to what’s available at the local garden center, hardware store or Farmer’s Market.
Gives a great creative outlet to “cabin fever” that sets in before the garden can be worked, allows you to be “growing something” early on.
There is greater flexibility on timing to get them started. You can start them to work with your schedule, or to take advantage of getting bigger, earlier producing plants in the garden sooner.
Starting your own seeds gives earlier veggies from the garden, as you start on your schedule, not depending on a regional greenhouse schedule. For example- here in AZ, most starts come from the central valley of CA, where timing is completely different, sometimes by a factor of several weeks.
Home gardeners can usually grow bigger, healthier plants than a commercial greenhouse, as there is more attention per plant. Less diseases/issues than from large scale grower.
Seed starting does require some planning and effort, not as easy as going down and picking out what seedling to buy.
Does require some set up and equipment, but not much to get started. Will require some space, but not much on start-up.
Transplants give you a head start on weeds and the weather. A tomato or pepper that is 2 feet tall will have little to no competition from weeds that are just getting started.
Now that you know the pro’s and con’s of starting your own seeds, how does one go about actually doing it? As with just about anything, there is some planning and preparation involved, but not too much. Remember how we talk about getting started in the garden- start small, start simply, but get started? The same thought process applies here as well. Set yourself up for success, not frustration, headaches and failure. Take the time to do some initial planning and set up and you’ll be off to a great start.
Plan and arrange the seed starting area
Start simply and easily, you may have most of the items on hand.
A key factor for successful germination is a warm area to sprout seeds- can be the top of a refrigerator, freezer, window sill in south-facing room. etc. Most of the calls we receive about seeds not germinating is traced to this factor. When the temperature of the soil is optimum- seeds can and will “pop” in 5 days, no matter if they are tomatoes, peppers or eggplant! When the soil temperature is less than 70F, it can take 2 weeks to sprout- there is that much of a difference!
Supplemental heat may be needed. Soil temperatures need to be above 80F for faster germination. The ideal soil temperature for tomatoes, peppers and eggplant is 85F. Rarely are people comfortable at that temperature! Air temperature may be 5-10F different than soil temperature due to evaporative effects of moist soil. Heating pads, germination heat mats, old electric blankets, etc can work to raise soil temperature to where it needs to be. Monitor soil temperatures to avoid over-heating. A heat mat will work even if the air temperature is 60-65F.
Supplemental lighting may be needed after seeds sprout and develop true leaves. This can range from specific grow lights to common fluorescent fixtures with grow bulbs. Lights need to be moveable to keep about 2-4 inches above plants. Seedlings need 14-18 hours of light per day.
Humidity levels need to be high when seeds are sprouting, then less so as they develop and continue to grow. Domed lids on grow trays are great and have adjustable vents to maintain humidity levels. Plastic sheeting, such as painter’s drop cloth, will work just as well. Make sure to inspect the seedlings for mold or fungus growth on top of the soil, which is an indication of too much humidity and too little air circulation. After the seedlings grow their second set of true leaves, humidity is less important. Of course, in areas of high humidity, often nothing else is needed.
Once the area is planned and prepared, the equipment is all that is left and you’re ready to start some seedlings! The equipment can be very basic of pretty involved, but again- start small and simple. It is amazing how well seeds sprout in a soil block that is free or paper pot that is next to free! Sometimes they sprout better than in much more expensive and complex equipment.
Gather the equipment needed
See our Seed Starting Department for books and tools to help you be more successful in starting your seeds.
Plastic trays for seedling sets and containers for individual seedlings. Domed lids or plastic sheeting may be needed in low humidity areas.
Seed cups or containers. These can range from peat pots to homemade paper pots to handmade soil blocks to recycled yogurt/dixie cups. What is needed is something that will support the individual seedlings and feed them until they are ready for transplanting.
Soil or seed starting mix. These range from several readily available commercial ready to use seed starting mixes that have no soil and are sterile to lessen the chance of fungus and diseases, to a number of ingredients that make for a great homemade seed starting mix. We will cover some of these in more depth in another article.
Misters or sprayers. A small squirt bottle sprayer or mister works great to apply very small amounts of water to the seedlings. A small hand pump sprayer can be valuable as well to give a bit more water without having to pump constantly, especially for larger amounts of seed trays.
Soil thermometer. This gives you an accurate indication of what the soil temperature is, regardless of the air temperature.
Introduction to Seed Starting video with Terroir Seeds
We have created a short video showing how we have started seeds for several years now. This is the result of many experiments and really works well for us. By no means is this is the only way to do it, as we know of several different but equally effective ways to get seedlings started at home. This is just what works for us, and the expense didn’t break the bank. We constructed this in stages after experience and experiments taught us what works in our situation. This takes up little space and produces a lot of seedlings for our trial garden. Take a look and please let us know your thoughts, ideas and experiences that we can share with everyone else!

Szechuan Buttons – Secret Ingredient of Celebrity Chefs and Master Bartenders
One of our best selling herbs is the Toothache Plant or Szechuan Buttons. Spilanthes oleracea, also known as Acmella oleracea is a low-growing plant with bronze-purple leaves hosting yellow/red “gumdrop” flowers that bloom repeatedly summer through fall. The medicinal uses of spilanthes have been around for a long time. A mouth rinse of spilanthes extract can be used daily to promote gum health. In vitro testing has shown that the plant’s extract has strong effect against E.coli, pseudomonas, salmonella, klebsiella pneumonae and staphylococcus albus, as well as inhibiting the growth of candida albicans. Improves digestion, eases flatulence, improves the appetite, and helps to overcome nausea and vomiting by its stimulating effect on the salivary glands.
We don’t sell spilanthes soleley for its medicinal properties but also for its “Rock Star” qualities. NPR has a story about using the Szechuan Buttons in high-end restaurants and bars. The Washington Post did one as well. We were very intrigued and had to grow these amazing little plants last summer to see for ourselves, had a nibble of the traditionally used leaves and it makes your mouth tingle. It is like the old pop rocks candy, a very effervescent feeling. The fresh buttons sell for somewhere around $40 for a bag of 30 buttons, but if you grow them yourself it’s around $3.50 for a packet of 30 seeds, and you’ll grow hundreds of buttons! Freezing does not hurt their buzz, so you can have them year round.
We also had to try out the buttons on a cocktail. What follows is a short photo essay of this experience. We would highly recommend growing the plant for its rock star presence but also for the beauty it adds to the garden.
Starting with this –
Szechuan Buttons in the garden
We selected three great specimens.
Szechuan Buttons ready for use
With the ingredients gathered, we were ready to start.
All ingredients are ready
After the drink is made, the magic is ready to be put into play! The Buttons must be pressed into the rim of the glass firmly, as the bud needs to be slightly crushed to release the “Buzz”.
Szechuan Buttons in action
We were surprised at the strength of the tingle and how long it lasted. Any part of our mouths or tongues that touched the rim of the glass had an immediately noticeable tingling or buzzing feeling, along with some numbness of the tongue that lasted at least 20 minutes. The height of the effect easily lasted 10-12 minutes, with a slow tapering off toward the end.
Seeing how easy it is to grow these, you can be the producer of a lot of “Buzz”!

Heirloom beets are one of the earlier crops to be planted, and one of the first to be enjoyed early in the Spring. Here’s a great recipe with an unusual preparation that really brings out the earthy goodness of fresh home-grown beets. The secret is slow roasting at about 300°F for almost an hour. I prefer to do this in our charcoal fired Kamado grill, a Japanese clay covered BBQ which holds the heat amazingly well and gives an incredible rich but lightly smoky flavor. The beets turn out heavenly, and I’m often asked what I did to make them so delicious. Oven roasted is a very good second choice, just make sure to roast them slow and long – it caramelizes the sugars in the beets, making them a surprise all of their own.
The Dijon mustard plays a nice counterpoint to the richness of the beets. For some additional flavors, add some heirloom carrots or overwintered onions to the mix- roast along with the beets! Keep in mind that young beets – less than 2 inches in diameter- are sweet like carrots.
Trim stem and root from beets. Place whole beets in roasting pan; add 1 tablespoon olive oil, salt and pepper. Toss to coat.
Roast at 400° for 45 minutes or until beets are tender. Beets are tender when easily pierced with a fork or toothpick.
While beets are roasting whisk mustard, orange juice, sugar, and vinegar in bowl. Whisk in remaining 3 tablespoons olive oil and rosemary. Set aside.
When beets are cool enough to handle, rub to remove skins; cut into quarters. Add warm beets to bowl and toss with dressing. Let stand 30 minutes while beets absorb dressing.
Now that the days are becoming slightly longer, the holidays are over and life is getting back to whatever consists of normal for you and your family, it’s time to dig into our garden seed catalog and start planning the eternally anticipated Spring garden.
After spending a little time reading – and realizing that you want to plant one of everything – the realization sinks in that this could be some work, and that’s before the real work of actually digging in the garden even begins!
What to plant, how to plant, when to plant, what will grow for me, should I start my heirloom tomatoes from seed or just buy starts, what do I need to do for my soil, and what exactly is succession planting are all questions that crop up and need answers.
All of a sudden, a garden seems pretty intimidating, definitely not for amateurs and something that might be best left to the experts. Well guess what? Everyone was an amateur at some point, starting out with not much knowledge and needing some help. It is easier to start your home garden today than in any other time in history, as there are mountains of information and education out there and it is all pretty easy to find. The Internet is full of good gardening advice in many areas.
What we will look at today are some points to consider about your home garden, we’ll do some initial planning and pass along some tools that will be very helpful in building your toolbox of gardening knowledge and problem solving. Let’s get started!
Now is the perfect time to start planning for what you want to do in your garden next year. Just get the planning started, then work on it as ideas bubble up from your subconscious. This way, you won’t be caught short when time becomes an issue in a couple of months.
To help you get the process rolling, we have the following points to consider, along with some tools to help get you there sooner.
1. Review last year’s garden. How did it do? Did you start enough seeds/seedlings to compensate for losses due to transplanting, weather, critters etc.? Were plants healthy and productive, or were there issues that need some researching, such as pests, insects, disease, weather conditions to plan for or try to mitigate?
We found that the rabbits and deer were a factor we didn’t even consider in planning how much of the White Eagle corn we planted as a test plot for growing our own heirloom seed corn. They took out almost a third of our crop! This is something that we will be planning for (in a couple of ways) in this year’s planting.
2. Plan early for varieties that might need a longer growing season, or take longer to germinate. This isn’t just a beginner’s mistake, many experienced gardeners get caught out on the timing for their garden. We’ll show you how to do the date planning later on in this article. Then it is just a matter of writing down the seed starting dates on a garden calender and sticking to the plan.
If you give yourself at least a week “cushion” on the timing, you won’t be stressed if you can’t get the seeds started or transplanted on the date you’ve chosen, whether due to busy schedules or the weather or some other unforeseen happening.
3. Try one new variety this year that you’ve never had out of your garden. It may be something that you don’t think you’ll like, or it may just be something that you’ve never had fresh just moments before from your own garden.
This was eggplant for me, and I now love it- from my own garden. This year it just might be turnips, as I’ve never had fresh turnips!
4. Make a garden plan. This can greatly help with spacing, intensive planting, succession planting and growing more food in your existing space. Also helps with small space/container growing.
Download and use our Garden Journal for more information and help.
Mother Earth News has a Vegetable Garden Planner that has several short videos showing how to get started. It is free for the first 30 days, and is $25 for a years subscription. There are other free garden plannersif you do a search online.
5. Grow an herb this year. You won’t believe the exquisite flavor that one fresh heirloom herb can bring to your kitchen and meals. If you’ve grown herbs before, or are growing some now- try a new one.
To start, try something that is used extensively in cooking like Basil, Oregano or Thyme. All of these can be dried and used year round, with the added benefit of saving you money buying expensive dried herbs.
6. Plant some pollinator attractants. These can be herbs or flowers and will dramatically help your garden’s production. Just one or two varieties planted throughout the garden can make a huge difference.
7. Plan to save one variety of seed this year. Start with something easy and something that you are interested in. Read our Seed Saving articles to get started, or take a look at these books- “Saving Vegetable Seeds” is a new book that has great illustrations and introductions, while “Seed to Seed” is the established reference for all things seed saving.
8. Plant enough to share with a neighbor/senior center home or food bank. Plant an extra row if possible, a couple of plants extra if space is small. The difference even one gardener can make in another’s life is extraordinary!
Plant a Row for the Hungry is a public service program of the Garden Writers Association and has donated over 14 million pounds of food since 1995 to feed hungry folks in our local neighborhoods and communities across the nation. This is without government assistance, oversight, subsidy or bureaucratic red tape – just people helping people. It was started in Anchorage, Alaska by Jeff Lowenfels to provide food for Bean’s Cafe, a local soup kitchen.
9. Get your kids or grand-kids involved. Have them help plan the garden and plant something just for them. Don’t have kids or grand-kids? Use the neighbors, friends, etc. Start them on growing food and learning where our food comes from and how it gets to the plate. You will be surprised at how interested kids are in the garden once they are there. Combine this with #7 above and help them learn the full cycle of the garden from planting a seed to harvesting a seed.
10. Cook a meal with those kids mentioned above. Plan a simple, easy to make meal. Have them help harvest, clean and prepare the meal.
11. Review our website. If you have questions or need help, please, email or call us. We’re here to help you be more successful in your garden. We make our living on the sale of heirloom seeds, tools, books, etc. but if we can help you be more successful in your garden, everyone wins.
Here’s how we see it: you have a better garden, more fresh veggies and more food. You give some to your neighbor, who notices your garden is much more productive, disease, insect and pest resistant and they ask how you do it. You share what you’ve learned and they have a better garden with more food. They then help create a better, more resilient local food system.
Yes, we may get a few more customers, but that isn’t the point or the focus. Another possibility is that you do plant a row to donate, and make the local food bank, soup kitchen or retirement home’s day with fresh, healthy and tasty food.
All right, then- now that you’ve got plenty of ideas of what to do with your garden this year, how do you get started?
Getting the timeline down is one of the hardest parts, as there is some real confusion on when to start seeds, when to till the soil, when to direct sow these seeds and transplant those to get some great food growing in your garden. There is no fail-proof method, as even experience can be tripped up by an early spring followed up by a sneaky late cold snap that kills your tender seedlings.
Here is a good tool to get some real world, historical weather data from the three closest weather stations to your zip code- the First and Last Frost Dates by Zip Code. Once you are there, add in your Zip code, click Go and this is similar to what you will see:
First and Last Frost Dates by Zip Code
We are using our Zip code of Chino Valley, AZ for this example. Click on the photo to make it bigger.
There is a lot of useful information here, so let’s break it down a bit to make sense of all of this. The three weather stations are included for locations that might not be really close to any one of the stations, so you can make an educated guess on dates. We are closest to the Chino Valley weather station, so that is what we will use.
The first box says this-
Each winter, on average, your risk of frost is from October 5 through May 26.
Almost certainly, however, you will receive frost from October 22 through May 5.
You are almost guaranteed that you will not get frost from June 15 through September 17.
Your frost-free growing season is around 132 days.
This is good information to use in planning your garden and in choosing varieties to plant that will be able to grow in your garden, with your growing season. For instance- if your growing season is 60 days, like our friends in Flagstaff, AZ, then you want to be careful in choosing too many things that need 90 days to produce food, if you don’t have a greenhouse or shelter for protection. This information also gives you a good idea of first and last frost dates, but we can get more selective with the information below this top box.
The next three boxes are the historical data from the closest weather stations to your Zip code. The top line of each box is the chance- in percentage- of a frost happening. So 10% is a really low chance, while 90% is a high chance. The temperatures on the left side represent the different frosts- 32F is considered a light frost, 28F is a moderate frost and 24F is a killing or hard frost. For garden planning, look at the 32F line. I usually choose the 50% column to start, then work from there. In our example 50% chance of a 32F frost in Chino Valley in Spring is May 4. This corresponds with the traditional time to direct sow and transplant of May 7-10 locally. Direct sowing cool season crops can be done up to 4-6 weeks earlier in some locations.
To get the timeline correct on starting seedlings like tomatoes, peppers and eggplant- subtract at least 6-8 weeks to allow the seedlings time to grow and get strong enough for transplanting. The more time seedlings have, the bigger and stronger they will be. They will also take up more space, so allow for that as well. We try to give the tomatoes and peppers a minimum of 8 weeks before transplanting them, as we always seem to have some weird weather event that causes havoc with younger, more tender seedlings. We’ve found that the larger ones blow through a heavy wind or late frost without too much worry.
So here is how the math looks and works-
In our example May 4 is the earliest date to direct sow and transplant tender varieties. We want to subtract 8 weeks from that to determine our seed starting date for transplants such as tomatoes, peppers and eggplant. This takes us to March 9, give or take a week or so. This is where the beauty of planning comes in, as you can “fudge” the dates by a week or so on each end if needed and still be very successful. For example: you are swamped the week you are scheduled to plant seeds for transplants, and get them planted one week late. On the other end, you can very easily just wait one more week if needed (weather, hectic schedule) before transplanting the seedlings into the garden. Getting them started a little earlier and waiting a little longer will only give you bigger, stronger transplants.
This tool also works very well for planning your timeline for direct sowing those early season, cool weather crops that go in earlier than anything else. All of our seed packets have planting instructions on the back, and some will indicate that they can be planted a certain number weeks before the last frost.
One last tool to leave you with is your local Master Gardeners. Click on the link, select your state, then county to see where your local Master Gardeners are located. These are volunteers through the land grant universities in each state. They will have really good, accurate information on your local conditions, pest and disease pressures and general gardening information. They are good folks to get to know. Some are mainly flower gardeners, while others focus more on vegetables, so talk with a few of them.
The Master Gardener manual lists good planting timelines for local conditions for pretty much all of the garden crops, what kind of production can be expected for each crop and how many feet of garden to plant per person. You can also do a search for “Arizona planting guide” or “Arizona garden planting guide” substituting Arizona for your state. The search results will show something like “Arizona Master Gardener Manual”. You can then download or print this to have for your future reference. The local Master Gardener office can also make copies for you if you ask.
There you have it, a lot of information to help you get more out of your garden and some great tools to get the planning and timing under control. It can seem daunting at first, so start small and simple, get a good feel for how it works for you, then expand as needed. Make sure to use the Garden Journal to keep track of what worked well and what didn’t so you don’t get frustrated and repeat your mistakes. As always, we are here to help and advise you on growing a better, bigger garden!

Seed Starting Media for the Home Gardener
The importance of proper seed starting mediaSeed starting media is what is used to, you guessed it, start your seeds in! Why does starting seeds require its own media? Why not just use some good garden soil or well-aged compost? What is the difference anyway? These are valid questions that all too often go unanswered, leading to disappointment, frustration and failure for the home gardener trying to get a jump on the season by starting their own seeds for transplants.

These are all things that are just not possible to control outside, forcing the gardener to wait until conditions are right before sowing the seeds directly into the soil and hoping that the weather cooperates. Thus the entire reason to start your own seeds inside, in a nutshell! You have control- control of the choice of what to plant, what varieties of tomatoes, peppers and such that are not available at the local garden center or nursery, and control of all of the variables that will grow a healthy, sturdy and productive member of the garden.
It all starts with the choice of the right seed starting media or mix. Get it right and you are well on your way to success. Get it wrong and you could have some challenges that slow you down. Luckily, it is not difficult at all! When you visit your local garden center, home improvement store or local market, it might be confusing on which growing media to buy.

Perlite
Perlite– An amorphous volcanic glass expanded to about 13 times its original volume by heating to 1,800F; it is used as a soil additive to help prevent water loss and soil compaction and is white in color. Perlite provides aeration and optimum moisture retention for superior seedling growth. It is sterile and has a pH of approximately 7, or neutral. Used to condition garden soil to improve aeration and drainage.
Vermiculite
Vermiculite– A mica mineral expanded by heating it to 1,400F; used as part of peat-lite mixes. Similar to perlite it is lightweight, highly absorbent, increases aeration and moisture retention, and minimizes fertilizer leaching.
Peat Moss
Peat moss– Organic material used in many soil mixes to grow plants in. It comes from Peat bogs, which are natural deposits of peat moss. Peat Bogs are found in very Northern Countries such as Canada. This is a finite resource.
Peat pots– Pots made from compressed peat moss and paper.
Rock Wool
Rock Wool– A growing media is an inorganic product that is made by melting together at a very high temperature a mixture of basalt, coke and limestone into lava which is blown into a large spinning chamber which pulls the lava into fibers like “cotton candy”. Rock wool fibers hold a lot of water; this medium is usually used in greenhouse production.
Compressed Coconut Coir
Coir– A natural fiber extracted from the husk of coconut and has a large capacity to absorb water and still provide aeration. It is a strongly recommended substitute for sphagnum (Peat) moss because it is free of bacterial and fungal spores, and produces good results without the environmental damage caused by peat mining.
Wetting agent– Material added to water to reduce the surface tension and make the water wetter.
Seed Starting Mix
Many common Seed Starting Potting Mixes will contain peat moss, perlite, a fertilizer and a wetting agent. There are many different brands of Seed Starting Mixes on the market or you can create your own. Take a look at our Seed Starting Department for ideas and tools to help you get the best out of your seed starting efforts.
Here are a couple of hand-made mixes from The New Seed Starters Handbook by Nancy Bubel. Nancy was the author of many books at Rodale and the author of the Storey Publication Grow Super Salad Greens.
Good and Simple Potting Soil
One part finished compost
One part vermiculite
Home-Style Potting Mix
One part finished compost
One part either loose garden soil or potting soil
One part sharp sand, perlite or vermiculite or a mixture of all three.
If you are a beginner it might be easiest to buy a bagged mix or a tray with coir pellets to start with. After a little experience you will find what works best for you.
A personal favorite is using a soil blocker and creating your own custom mix based on Eliot Coleman’s methods. Chapter 14 of The New Organic Grower covers the complete use of soil blocks and blocking mixes. If you start a lot of starts or are a larger grower this method might be worth exploring.
With an understanding of the importance of a good seed starting mix, and the ingredients commonly available, you have the tools needed to have a successful start to your seedlings, a more productive garden and great home grown food. We will be continuing the planning, seed starting and planting series with some seed starting basics, tools and experiences that have helped us have a high success rate.
Large Leaf Sorrel or Lemonade Leaf
French sorrel is known as “lemonade leaf” and has been prized for its nutritional and culinary qualities for centuries. In many climates it will nativize.
Successful Heirloom Seed Starting for the Home Gardener
When it comes to starting their own heirloom seeds, home gardeners seem to be in two distinct camps- those that are really positive about the process and results, and those that aren’t. The folks that aren’t too excited about starting their own seeds usually have a good reason- they’ve had some failures with die-off and had to scramble to buy starts at the local garden center and wound up with something that they didn’t really want. Others haven’t tried their own starts, but feel that it is complicated or difficult. There are some very compelling reasons to start your own seedlings, but there are some challenges to overcome as well. We will look at several items to consider in making the decision of whether or not to do your own starts, along with some tips to get you started successfully.
Why start your own seeds? What advantages/disadvantages are there?
Now that you know the pro’s and con’s of starting your own seeds, how does one go about actually doing it? As with just about anything, there is some planning and preparation involved, but not too much. Remember how we talk about getting started in the garden- start small, start simply, but get started? The same thought process applies here as well. Set yourself up for success, not frustration, headaches and failure. Take the time to do some initial planning and set up and you’ll be off to a great start.
Plan and arrange the seed starting area
Once the area is planned and prepared, the equipment is all that is left and you’re ready to start some seedlings! The equipment can be very basic of pretty involved, but again- start small and simple. It is amazing how well seeds sprout in a soil block that is free or paper pot that is next to free! Sometimes they sprout better than in much more expensive and complex equipment.
Gather the equipment needed
See our Seed Starting Department for books and tools to help you be more successful in starting your seeds.
Introduction to Seed Starting video with Terroir Seeds
We have created a short video showing how we have started seeds for several years now. This is the result of many experiments and really works well for us. By no means is this is the only way to do it, as we know of several different but equally effective ways to get seedlings started at home. This is just what works for us, and the expense didn’t break the bank. We constructed this in stages after experience and experiments taught us what works in our situation. This takes up little space and produces a lot of seedlings for our trial garden. Take a look and please let us know your thoughts, ideas and experiences that we can share with everyone else!
Szechuan Buttons or Toothache Plant – Rock Star of the Garden
Szechuan Buttons – Secret Ingredient of Celebrity Chefs and Master Bartenders
One of our best selling herbs is the Toothache Plant or Szechuan Buttons. Spilanthes oleracea, also known as Acmella oleracea is a low-growing plant with bronze-purple leaves hosting yellow/red “gumdrop” flowers that bloom repeatedly summer through fall. The medicinal uses of spilanthes have been around for a long time. A mouth rinse of spilanthes extract can be used daily to promote gum health. In vitro testing has shown that the plant’s extract has strong effect against E.coli, pseudomonas, salmonella, klebsiella pneumonae and staphylococcus albus, as well as inhibiting the growth of candida albicans. Improves digestion, eases flatulence, improves the appetite, and helps to overcome nausea and vomiting by its stimulating effect on the salivary glands.
We don’t sell spilanthes soleley for its medicinal properties but also for its “Rock Star” qualities. NPR has a story about using the Szechuan Buttons in high-end restaurants and bars. The Washington Post did one as well. We were very intrigued and had to grow these amazing little plants last summer to see for ourselves, had a nibble of the traditionally used leaves and it makes your mouth tingle. It is like the old pop rocks candy, a very effervescent feeling. The fresh buttons sell for somewhere around $40 for a bag of 30 buttons, but if you grow them yourself it’s around $3.50 for a packet of 30 seeds, and you’ll grow hundreds of buttons! Freezing does not hurt their buzz, so you can have them year round.

We also had to try out the buttons on a cocktail. What follows is a short photo essay of this experience. We would highly recommend growing the plant for its rock star presence but also for the beauty it adds to the garden.
Starting with this –
Szechuan Buttons in the garden
We selected three great specimens.
Szechuan Buttons ready for use
With the ingredients gathered, we were ready to start.
All ingredients are ready
After the drink is made, the magic is ready to be put into play! The Buttons must be pressed into the rim of the glass firmly, as the bud needs to be slightly crushed to release the “Buzz”.
Szechuan Buttons in action
We were surprised at the strength of the tingle and how long it lasted. Any part of our mouths or tongues that touched the rim of the glass had an immediately noticeable tingling or buzzing feeling, along with some numbness of the tongue that lasted at least 20 minutes. The height of the effect easily lasted 10-12 minutes, with a slow tapering off toward the end.
Seeing how easy it is to grow these, you can be the producer of a lot of “Buzz”!
Dijon Roasted Heirloom Beets
Heirloom beets are one of the earlier crops to be planted, and one of the first to be enjoyed early in the Spring. Here’s a great recipe with an unusual preparation that really brings out the earthy goodness of fresh home-grown beets. The secret is slow roasting at about 300°F for almost an hour. I prefer to do this in our charcoal fired Kamado grill, a Japanese clay covered BBQ which holds the heat amazingly well and gives an incredible rich but lightly smoky flavor. The beets turn out heavenly, and I’m often asked what I did to make them so delicious. Oven roasted is a very good second choice, just make sure to roast them slow and long – it caramelizes the sugars in the beets, making them a surprise all of their own.The Dijon mustard plays a nice counterpoint to the richness of the beets. For some additional flavors, add some heirloom carrots or overwintered onions to the mix- roast along with the beets! Keep in mind that young beets – less than 2 inches in diameter- are sweet like carrots.
Dijon Roasted Heirloom Beets
Makes approximately eight servings.
Planning and Planting Your Spring Garden
Now that the days are becoming slightly longer, the holidays are over and life is getting back to whatever consists of normal for you and your family, it’s time to dig into our garden seed catalog and start planning the eternally anticipated Spring garden.
After spending a little time reading – and realizing that you want to plant one of everything – the realization sinks in that this could be some work, and that’s before the real work of actually digging in the garden even begins!
What to plant, how to plant, when to plant, what will grow for me, should I start my heirloom tomatoes from seed or just buy starts, what do I need to do for my soil, and what exactly is succession planting are all questions that crop up and need answers.
All of a sudden, a garden seems pretty intimidating, definitely not for amateurs and something that might be best left to the experts. Well guess what? Everyone was an amateur at some point, starting out with not much knowledge and needing some help. It is easier to start your home garden today than in any other time in history, as there are mountains of information and education out there and it is all pretty easy to find. The Internet is full of good gardening advice in many areas.
What we will look at today are some points to consider about your home garden, we’ll do some initial planning and pass along some tools that will be very helpful in building your toolbox of gardening knowledge and problem solving. Let’s get started!
Now is the perfect time to start planning for what you want to do in your garden next year. Just get the planning started, then work on it as ideas bubble up from your subconscious. This way, you won’t be caught short when time becomes an issue in a couple of months.
To help you get the process rolling, we have the following points to consider, along with some tools to help get you there sooner.
1. Review last year’s garden. How did it do? Did you start enough seeds/seedlings to compensate for losses due to transplanting, weather, critters etc.? Were plants healthy and productive, or were there issues that need some researching, such as pests, insects, disease, weather conditions to plan for or try to mitigate?
We found that the rabbits and deer were a factor we didn’t even consider in planning how much of the White Eagle corn we planted as a test plot for growing our own heirloom seed corn. They took out almost a third of our crop! This is something that we will be planning for (in a couple of ways) in this year’s planting.
2. Plan early for varieties that might need a longer growing season, or take longer to germinate. This isn’t just a beginner’s mistake, many experienced gardeners get caught out on the timing for their garden. We’ll show you how to do the date planning later on in this article. Then it is just a matter of writing down the seed starting dates on a garden calender and sticking to the plan.
If you give yourself at least a week “cushion” on the timing, you won’t be stressed if you can’t get the seeds started or transplanted on the date you’ve chosen, whether due to busy schedules or the weather or some other unforeseen happening.
3. Try one new variety this year that you’ve never had out of your garden. It may be something that you don’t think you’ll like, or it may just be something that you’ve never had fresh just moments before from your own garden.
This was eggplant for me, and I now love it- from my own garden. This year it just might be turnips, as I’ve never had fresh turnips!
4. Make a garden plan. This can greatly help with spacing, intensive planting, succession planting and growing more food in your existing space. Also helps with small space/container growing.
Download and use our Garden Journal for more information and help.
Mother Earth News has a Vegetable Garden Planner that has several short videos showing how to get started. It is free for the first 30 days, and is $25 for a years subscription. There are other free garden plannersif you do a search online.
5. Grow an herb this year. You won’t believe the exquisite flavor that one fresh heirloom herb can bring to your kitchen and meals. If you’ve grown herbs before, or are growing some now- try a new one.
To start, try something that is used extensively in cooking like Basil, Oregano or Thyme. All of these can be dried and used year round, with the added benefit of saving you money buying expensive dried herbs.
6. Plant some pollinator attractants. These can be herbs or flowers and will dramatically help your garden’s production. Just one or two varieties planted throughout the garden can make a huge difference.
7. Plan to save one variety of seed this year. Start with something easy and something that you are interested in. Read our Seed Saving articles to get started, or take a look at these books- “Saving Vegetable Seeds” is a new book that has great illustrations and introductions, while “Seed to Seed” is the established reference for all things seed saving.
8. Plant enough to share with a neighbor/senior center home or food bank. Plant an extra row if possible, a couple of plants extra if space is small. The difference even one gardener can make in another’s life is extraordinary!
Plant a Row for the Hungry is a public service program of the Garden Writers Association and has donated over 14 million pounds of food since 1995 to feed hungry folks in our local neighborhoods and communities across the nation. This is without government assistance, oversight, subsidy or bureaucratic red tape – just people helping people. It was started in Anchorage, Alaska by Jeff Lowenfels to provide food for Bean’s Cafe, a local soup kitchen.
9. Get your kids or grand-kids involved. Have them help plan the garden and plant something just for them. Don’t have kids or grand-kids? Use the neighbors, friends, etc. Start them on growing food and learning where our food comes from and how it gets to the plate. You will be surprised at how interested kids are in the garden once they are there. Combine this with #7 above and help them learn the full cycle of the garden from planting a seed to harvesting a seed.
10. Cook a meal with those kids mentioned above. Plan a simple, easy to make meal. Have them help harvest, clean and prepare the meal.
11. Review our website. If you have questions or need help, please, email or call us. We’re here to help you be more successful in your garden. We make our living on the sale of heirloom seeds, tools, books, etc. but if we can help you be more successful in your garden, everyone wins.
Here’s how we see it: you have a better garden, more fresh veggies and more food. You give some to your neighbor, who notices your garden is much more productive, disease, insect and pest resistant and they ask how you do it. You share what you’ve learned and they have a better garden with more food. They then help create a better, more resilient local food system.
Yes, we may get a few more customers, but that isn’t the point or the focus. Another possibility is that you do plant a row to donate, and make the local food bank, soup kitchen or retirement home’s day with fresh, healthy and tasty food.
All right, then- now that you’ve got plenty of ideas of what to do with your garden this year, how do you get started?
Getting the timeline down is one of the hardest parts, as there is some real confusion on when to start seeds, when to till the soil, when to direct sow these seeds and transplant those to get some great food growing in your garden. There is no fail-proof method, as even experience can be tripped up by an early spring followed up by a sneaky late cold snap that kills your tender seedlings.
Here is a good tool to get some real world, historical weather data from the three closest weather stations to your zip code- the First and Last Frost Dates by Zip Code. Once you are there, add in your Zip code, click Go and this is similar to what you will see:
First and Last Frost Dates by Zip Code
We are using our Zip code of Chino Valley, AZ for this example. Click on the photo to make it bigger.
There is a lot of useful information here, so let’s break it down a bit to make sense of all of this. The three weather stations are included for locations that might not be really close to any one of the stations, so you can make an educated guess on dates. We are closest to the Chino Valley weather station, so that is what we will use.
The first box says this-
This is good information to use in planning your garden and in choosing varieties to plant that will be able to grow in your garden, with your growing season. For instance- if your growing season is 60 days, like our friends in Flagstaff, AZ, then you want to be careful in choosing too many things that need 90 days to produce food, if you don’t have a greenhouse or shelter for protection. This information also gives you a good idea of first and last frost dates, but we can get more selective with the information below this top box.
The next three boxes are the historical data from the closest weather stations to your Zip code. The top line of each box is the chance- in percentage- of a frost happening. So 10% is a really low chance, while 90% is a high chance. The temperatures on the left side represent the different frosts- 32F is considered a light frost, 28F is a moderate frost and 24F is a killing or hard frost. For garden planning, look at the 32F line. I usually choose the 50% column to start, then work from there. In our example 50% chance of a 32F frost in Chino Valley in Spring is May 4. This corresponds with the traditional time to direct sow and transplant of May 7-10 locally. Direct sowing cool season crops can be done up to 4-6 weeks earlier in some locations.
To get the timeline correct on starting seedlings like tomatoes, peppers and eggplant- subtract at least 6-8 weeks to allow the seedlings time to grow and get strong enough for transplanting. The more time seedlings have, the bigger and stronger they will be. They will also take up more space, so allow for that as well. We try to give the tomatoes and peppers a minimum of 8 weeks before transplanting them, as we always seem to have some weird weather event that causes havoc with younger, more tender seedlings. We’ve found that the larger ones blow through a heavy wind or late frost without too much worry.
So here is how the math looks and works-
In our example May 4 is the earliest date to direct sow and transplant tender varieties. We want to subtract 8 weeks from that to determine our seed starting date for transplants such as tomatoes, peppers and eggplant. This takes us to March 9, give or take a week or so. This is where the beauty of planning comes in, as you can “fudge” the dates by a week or so on each end if needed and still be very successful. For example: you are swamped the week you are scheduled to plant seeds for transplants, and get them planted one week late. On the other end, you can very easily just wait one more week if needed (weather, hectic schedule) before transplanting the seedlings into the garden. Getting them started a little earlier and waiting a little longer will only give you bigger, stronger transplants.
This tool also works very well for planning your timeline for direct sowing those early season, cool weather crops that go in earlier than anything else. All of our seed packets have planting instructions on the back, and some will indicate that they can be planted a certain number weeks before the last frost.
One last tool to leave you with is your local Master Gardeners. Click on the link, select your state, then county to see where your local Master Gardeners are located. These are volunteers through the land grant universities in each state. They will have really good, accurate information on your local conditions, pest and disease pressures and general gardening information. They are good folks to get to know. Some are mainly flower gardeners, while others focus more on vegetables, so talk with a few of them.
The Master Gardener manual lists good planting timelines for local conditions for pretty much all of the garden crops, what kind of production can be expected for each crop and how many feet of garden to plant per person. You can also do a search for “Arizona planting guide” or “Arizona garden planting guide” substituting Arizona for your state. The search results will show something like “Arizona Master Gardener Manual”. You can then download or print this to have for your future reference. The local Master Gardener office can also make copies for you if you ask.
There you have it, a lot of information to help you get more out of your garden and some great tools to get the planning and timing under control. It can seem daunting at first, so start small and simple, get a good feel for how it works for you, then expand as needed. Make sure to use the Garden Journal to keep track of what worked well and what didn’t so you don’t get frustrated and repeat your mistakes. As always, we are here to help and advise you on growing a better, bigger garden!
