What Trap Crops Are and How They Work

Trap cropping – also called intercropping – is an older pest control approach used by commercial growers that is not widely known or used in home gardens, but it should! Essentially, a trap crop acts as a decoy or sacrificial plant for invading pest insects and luring them away from your vegetables. Once the destructive insects attack the trap crop, you can deal with them there instead of on your valuable food crops. Techniques include removal or spraying with a soap-based solution or natural recipe, all the way up to using insecticides on the trap crop.

Using trap crops isn’t a “one-size-fits-all” approach, as each crop attracts a specific set of pests. However, it fits perfectly into a home garden, no matter how big or small. Almost everyone can take advantage of trap crops, from traditional in-ground rows to raised beds to container gardens.

Trap cropping is one part of an integrated, organic management approach to gardening. Instead of just managing pests, this approach includes attracting beneficial insects that prey on the destructive ones while helping to pollinate your garden better. Other parts of organic management include planting cover crops and companion planting.

How to Use Trap Crops

There are two main ways to use trap crops: to test for specific pest insects and then to attract those pests to better control and minimize or prevent their damage to your desired food crop.

When testing for specific pests, the most accurate results are obtained by using a border planting approach surrounding the garden. This way, pest insects have to pass through the desirable trap crop to reach your food plants, making it easier to monitor the pests and make better choices about identifying and controlling them.

Destructive pest insects are most attracted to plants in the reproductive stage of growth – flowering, fruiting, or setting seeds. This is why most trap crops are planted before your desired food crop – anywhere from a few days to a couple of weeks earlier, depending on how long the trap crop needs to start flowering.  

After the insects attack your trap crop, you can be ruthless in controlling them – from spraying aggressive bug solutions and removing leaves up to removing the entire infested plant. Depending on the type of planting, this creates the first line of defense or an added layer of protection for your main vegetable, herb, or flower crop with no chemicals or sprays needed.

Definitions

Just as there are different ways to grow a garden – traditional rows, raised beds, containers, hoop houses, and greenhouses – there are different ways to plant trap crops that increase their effectiveness and benefits.

Border planting –  Just as it sounds, planting one or more pest-attracting crops outside of the garden or area where the desired crop is grown. This can be completely surrounding the garden or between the garden and where the pests come from – for example, between the garden and an open field.

Intercropping – Planting the trap crop in alternating rows or areas within the garden or desired crop. For example, planting a row of lovage on either side of your tomato row will attract tomato hornworms before they get to the tomatoes.

Mixed intercropping – Trap crops are planted among the desired crops with no distinction. This looks exactly like companion planting but for the opposite reason – you attract pest insects to the trap crop instead of bringing in beneficials. An example is planting red giant mustard among your cabbages to attract the cabbage caterpillar.

Trap Crops Chart

Now that you understand more about trap crops, how they work, and the different types of planting, it’s time to see exactly which crops can be used and what type of pests they help control.

Initially, you may be surprised to see so many familiar, common garden crops listed. However, remember your gardening experience – how many of these crops seemed to attract the exact pests listed here?

This is simply a different perspective or approach to deciding what to plant in your garden, when, and for what reason.

Remember, your main crops – vegetables, herbs, or flowers – are usually entirely different species than your trap crops, but not always. In long-season climates, an early group of cherry tomatoes is transplanted to attract common tomato pests, protecting the main planting 2 – 3 weeks later.

Concerns and Strategy

To get the most benefits from trap crops, you must be diligent in inspecting them for pest insects and take immediate, decisive action. This often means picking the bugs off, removing leaves, branches, or the entire plant in some cases. Appropriate action can also mean treating the pest insects by spraying, from a mild soapy solution or Garlic Juice Concentrate to our Home Garden Bug Solution.

Improper management of the trap crop can create “pest nurseries” –  just the opposite of what you are trying to do!

You must be ruthless in taking action with the trap crop – remember, it is a sacrificial target to protect your valuable crops.

It can be difficult to manage multiple pests simultaneously, as planting multiple trap crops can be larger than your garden. It’s best to use trap cropping to manage your biggest pest insect infestation, then use companion planting to attract beneficial insects to work on the other pests.

As mentioned above, trap cropping isn’t a silver bullet, a one-size-fits-all solution, but it can be a valuable tool in an integrated organic management approach. A diverse mixture of plants makes it far less likely that the destructive pest insects will settle on your main crops, and when they arrive, they will be followed by beneficial insects that feed on them.

A comprehensive organic pest control plan includes –

  • Diverse planting to confuse pests and prevent them from concentrating in one area.
  • Including multiple flower species – flower mixes are great – that attract beneficial insects.
  • Strategically placed trap crops targeting pests that you know are in the garden.
  • Crop rotations that follow cover crops that improve the soil while avoiding over-wintering soil-borne pests.

How To Get Started

The easiest yet most effective way to get started using trap crops in your garden uses these steps:

  • Identify the worst pest insect that attacks your garden, causing the most damage.
  • Choose which crop is most infested by that pest.
  • Using the chart above, find the trap crop for that pest and which planting method is best.
  • Determine when to plant your trap crop – how early before your main crop so it is flowering or setting fruit to attract the pest insects.
  • Plant one trap crop to experiment and learn with.

The level of your success depends on several factors, but you should see significant improvement in the population of pests, the amount of damage, and the health and amount of harvest in the first season you start using trap cropping.

Keep a notebook with your experiment’s details and results, successes and challenges, weather, and other related factors. After a couple of seasons, you should begin to form a clear picture of which direction is best for you and your garden in your particular climate.

This isn’t a quick-fix approach; it’s about understanding your garden better, more of a Systems Approach than a silver bullet. However, if you commit to an organic pest control approach, you will see a steady decrease in destructive pests and a comparable increase in beneficial insects. You will also see fewer damaged vegetables and increased harvests of healthy food from your home garden.

Citrus Flavors From 8 Easy to Grow Herbs

Fresh, bright and invigorating, the scent and flavor of citrus is most enjoyable for many gardeners, especially where citrus trees are not a possibility. Several different herbs and flowers have a pleasing citrusy scent or flavor – either lemon, lime or orange – either as the main fragrance or as a delicate note that brightens the scent.

Popular for teas, sachets, aromatherapy, and recipes, they bring a bright, cheerful flavor to dishes like pasta, fish, and chicken.

If you are looking to add a lovely citrusy aroma to your garden, here are eight herbs to consider!

Lemon Balm

A plant growing in the dirt on a sunny day.
Lemon Balm leaves

A proud member of the mint family, lemon balm (Melissa officinalis) is native to Europe and the Mediterranean and, if allowed, will spread into unwanted areas of your garden. It’s easy enough to contain in a planter or large container, or simply give it an area that it can fill in and be happy. Hardy to USDA Zone 5, it grows to about 2′ tall with abundant crinkled leaves and tiny white or pale blue flowers that attract a surprising amount of pollinators, given how petite the flowers are.

Rubbing the leaves brings out the lemon scent, and walking by the plant on a warm day repels biting insects. The scent is crisp, clean, and forward – you immediately get the heady fresh lemon-rind aroma that is very refreshing. Grow in part shade with moist soil or sunnier spots in cooler areas.

Harvest the leaves like basil with several cuttings during the season, and dry them to preserve that summer flavor into the winter, or chop the leaves and freeze in ice cubes for a lemony punch in iced teas or other drinks.

Lime Balm

A plant growing in the dirt on a sunny day.
Lime Balm leaves and flower

As you might expect, lime balm (Melissa officinalis ‘Lime’) is closely related to lemon balm, except with a flavor tilted towards the lime spectrum. Some gardeners experience it as a lemon-lime, while others comment on it being exceptionally limey, so soil and climate can make a difference in the scent and flavor.

Grow as you would lemon balm to raise the spirit and lift the heart!

Lemon Bee Balm

A plant growing in the dirt on a sunny day.
Lemon Bee Balm flowers

Completely different than the above two balms, lemon bee balm (Monarda citriodora) is both the perfect name and description of this highly fragrant plant. Being downwind of a thick stand will make you think you’ve come across a hidden lemon grove, then multitudes of hummingbirds and butterflies draw your eye to hundreds of minuscule compound flowers, stacked one on top of the other, marching up the stem. As you draw closer, the bees appear, covering the flowers in an intricate dance from flower to flower.

Both the leaves and flowers are used; making refreshing, calming lemon-scented teas and potpourri. The stalks make excellent additions to flower arrangements, both fresh and dried.

This annual native is fairly cold hardy, rarely killed by winter cold, surviving by underground rhizomes. They can spread in moderate climates, so use planters or pots to keep them contained, or give them an area of their own.

Lemongrass

A plant growing in the dirt on a sunny day.
Lemongrass plant

A favorite in Asian cooking, lemongrass (Cymbopogon citratus) looks similar to bunchgrass but with a pleasantly strong lemon scent and flavor. It has the same volatile oils as lemon rind, with the same fresh, clean, citrus flavor and scent. Easy to grow in pots and containers for cooler climates, lemongrass loves the heat thanks to its tropical origins.

Harvest by cutting a stalk at the outside of the clump near the base, leaving the rest to continue growing. Lemongrass is best used fresh, as it loses some of its lemony pungency when dried or frozen. This is why many gardeners will grow a pot of lemongrass for fresh use, moving it outside in the spring and summer, then bringing it inside for the fall and winter.

We love to ferment fresh lemongrass with chiles and garlic to make a delicious paste for Asian cooking.

Insect repellent booster –

Plant lemongrass and lemon balm together to double their individual insect-repellent powers!

Just standing in arms reach should be enough to fend off the worst of the biting bugs – consider planting a large pot to place near your summer barbeques.

They’re effective against mosquitos, gnats, and wasps, and you can break off a couple of leaves to rub on your skin or clothing to take the protection with you.

Lemon Basil

Lemon Basil leaves and seed pods

All of the flavor that makes basil such a beloved herb with a lemony punch gives lemon basil (Ocimum americanum) an exciting flavor to explore in the kitchen. Lemon and basil go well together, and this combines the best of both.

Heat-loving and repellant to biting insects, it makes a wonderfully different pesto and adds a boost of flavor to soups and stocks. As with other basil varieties, the flavor is at its peak when fresh-picked, but drying will retain some of the citrus aromas. Once it starts flowering, let some of the stalks go to seed to use as a spice and flavoring in salads, on sandwiches, and in summer iced tea.

This is another great candidate for growing in pots or containers that can be brought inside in cold weather to brighten up a winter dish.

Orange Scented Thyme

Orange Scented Thyme leaves and blossoms

A cousin to English Thyme with all of the complex flavors that makes it a garden favorite, yet orange scented thyme (Thymus fragrantissimus) packs a refreshing orange-mint fragrance in every leaf. The orange flavor follows the familiar thyme, adding complexity and interest to summer dishes. Use it in almost any recipe calling for traditional thyme where an orange undertone would be appreciated.

Harvest the sprigs before flower set for the highest essential oil content, allowing them to air dry for storage. Use both fresh and dried leaves to make a traditional thyme tea with a twist to soothe sore throats.

Nutmeg Flower/Black Cumin

Nutmeg Flower/Black Cumin

Rightfully called “The cure for everything but death”, nutmeg flower (Nigella sativa) shows off with blankets of gorgeous tiny blue-tinted flowers that produce the seeds that made them famous. The seeds are used as a spice for flavorings and medicinally for ailments. Also called Four Spice for its lemon-carrot scent followed by strawberry-pepper taste, it has flavored curries, breads, and cakes since ancient times.

Nutmeg flower prefers well-drained soil in full sun, and can often be found growing wild in rocky ground, fallow fields and scrubland. Because of its hardiness, it’s easy to grow and is often recommended for beginning gardeners, children, and low maintenance gardens.

French Sorrel

French Sorrel leaves

Known to many Europeans as the lemonade leaf, French sorrel (Rumex scutatus) is prized by chefs and is indispensable in French cuisine. The sour-citrus taste has been prized throughout the world for thousands of years as a wake-up call for taste buds dulled by bland winter foods.

Very hardy and early growing, sorrel was often one of the first fresh greens people ate each spring in the days before refrigeration. It is still a popular ingredient in spring tonics, and ancient Greeks and Romans used the herb to promote digestion.

Each one of these herbs is easy to grow in a container or pot, so no matter where you live the bright, refreshing flavors of citrus can be yours with little work and lots of rewards!

Soil Elixir Jump-Starts Your Garden’s Soil

One of the most anticipated times of year for gardeners is Spring, with the attendant planting season. Everything is new and fresh, a chance to start over and improve on last year’s garden. A big subject for gardeners is what to do with the soil to prepare it for planting. If you have been reading our articles over the past several years, you know we advocate building the health and vitality of the soil in a natural, biologically safe manner. Soil becomes healthier, more productive, and disease, weed, and pest resistant. It results in an upward spiral where the garden gets better year after year.

Here is a unique recipe for a spring garden elixir that is easy to mix, completely non-toxic, and hugely beneficial for jump-starting your garden’s soil and getting it ready for planting. It comes courtesy of Crop Services International, which has over 35 years of experience helping growers accomplish their goals. They provide a Non-Toxic/Biological/Sustainable approach to growing food, from a full-scale commercial farm to the home gardener. We have read “The Non-Toxic Farming Handbook,” which they wrote to educate ourselves on improving our knowledge and approach.

This recipe is based on a 20′ x 50′ garden or 1000 sq. ft. Adjust for your garden size.

Before You Start

This recipe and applications assume an average garden soil that is basically good but could use some help.

It works in fertile soils by subtracting the lime or gypsum application, adding compost before spraying the elixir.

It helps very poor soils, but won’t give as much effect.

Preparing your garden beds for the elixir will require a couple of things.

First, evenly spread a 50 lb bag of high calcium lime (for acidic soils) or gypsum (for alkaline soils) across your beds. Your local garden center should have this. If using lime, it should be high calcium lime with as low magnesium as possible. 5% or less is great, up to 10% is acceptable, but nothing over 10%. The higher magnesium percentage releases excess nitrogen into your soil, greatly decreasing its fertility. It also overloads both the chemical and biological processes of your soil. Do not buy Dolomite lime, as it has too much magnesium.

Then, follow with 100 lbs of rich, aged compost, spread evenly across your beds, about 2 full-sized wheelbarrows. This can be purchased or from your own compost pile. Again, the best is made by you, and it is easy – “Compost – Nourishing Your Garden Soil” has all the details.

After doing both of these, make and apply the elixir.

Notes on Ingredients

  • When purchasing the fish fertilizer, if you can find one with kelp or seaweed, even better. If you want the absolute best fish emulsion possible, brew your own! Read our “Best Homemade Fish Emulsion” for the recipe and instructions.
  • Blackstrap molasses is best for its increased mineral content. Unsulphured is preferred but not absolutely necessary. One of the best sources of inexpensive molasses is a feed store that supplies horses, which can be bought by the gallon for much less than at a supermarket.
  • Do not buy diet cola, as the Aspartame/NutriSweet used as the sweetener acts as a chelating agent, meaning it ties up the minerals and nutrients in the soil, making them unavailable to the plants. (It also does the same thing in your body!) The cola has Phosphorus to add to the mix along with sugars.
  • The beer adds B vitamins – no, not vitamin Beer!
  • The Borax powder adds Boron, one of the most important elements in the biochemical sequence of plant growth.
  • Cranberry juice is full of vitamins and minerals, acts as an antibacterial agent, and has an acidic pH. Depending on how the juice is processed, it can also contain significant amino acids.

Spring Garden Soil Elixir

This recipe is based on a 20′ x 50′ garden or 1000 sq. ft. Adjust for your garden size.

Author: Stephen Scott
Ingredients
  • 20-24 oz liquid fish fertilizer Home-made is best
  • 1/2 cup molasses Black strap has more nutrients
  • 16 oz bottle of cola – NOT DIET!
  • 24 oz beer 2 - 12 oz cans, any beer works
  • 1/2 cup Borax powder
  • 1 qt cranberry juice – make sure to get 100% cranberry juice, not a dilution
Instructions
  1. Mix well with a stirrer and thin with enough water to enable mixture to be sprayed with a tank type or hose-end sprayer.
  2. Apply the mix evenly over lime or gypsum and compost base with sprayer. If needed, go back over with second application to use up all of the batch, just make sure to apply evenly.

  3. Broad-fork or lightly rototill garden soil. If using a rototiller, don’t go more than 2 inches deep at the maximum. Most of the biological growth happens at the 2-3 inch mark and the soil is turned over an inch or so beyond what the tines reach. Tilling deeper only destroys microbial life in the soil, setting you back in your efforts to create and build biologically active soil.

Recipe Notes

It must be noted that the sprayer cannot have been used to spray any chemical treatments like herbicides, pesticides, etc. as this will put those chemicals onto your soil, killing the microbial life in the soil and feeding the chemicals to the plants, where you wind up eating them!

Seed Planting Elixir

Once you have applied the elixir and broad-forked or lightly tilled the soil, prepare your garden planning and seedlings. We have another planting elixir to use just after planting the seeds and transplanting the seedlings into the garden that we’ll share with you: In a gallon milk jug, mix 1/2 cup of fish emulsion, 1 tsp sugar (preferably raw or brown), and 1/2 cup of cola. Fill the jug with water and shake well. Apply the mixture over the seeds and transplants. Each gallon will treat approximately a 50-foot row.

This is a great start towards sustainable, biological agriculture in your own garden. Remember, though, it is just a start, a good step in the right direction. To continue to make progress in knowledge and soil health, you need to find out where you are starting from. Do more reading, ask questions, and get a complete soil analysis, not just the widely offered NPK and pH soil tests. Spend the money to find out exactly where your garden soil is, and then you can make sound decisions on where you want and need to go. Then you won’t be guessing and shooting in the dark, trying to do what is right but not really knowing if you are making positive progress.

The More You Know – the Better You Grow

Eggplant gets its name from a small white Oriental variety that is rarely grown in the United States. We are used to seeing the large, shiny purple elongated globes, so the original name is somewhat of a mystery to most gardeners. It is known by other names around the world, including aubergine in Europe, brinjal in India, eggfruit, tomato-fruited eggplant, gilos, guinea squash, mad apple, and nasubi.

Fresh-picked, home-grown eggplant is mildly sweet and delicious, taking up other ingredients into itself when cooked. The all-too-familiar bitter, off-putting flavors come from fruits picked slightly unripe, trucked to a store that are almost a week old before appearing on the shelves. Grow your own and taste the differences!

History

A member of the Solanaceae or nightshade family, its cousins are tomatoes, peppers, and potatoes. Southeast Asia – likely India, China, Thailand, or Burma – is considered to be the center of origin where it still grows wild; a spiny, bitter, orange, pea-sized fruit that has been cultivated and refined for over 1,500 years.

The earliest uses seem to be medicinal as some of the earliest written Ayurvedic texts dating to around 100 BC describe the health benefits of using eggplant. The Chinese spent much time domesticating and breeding for desirable traits, as Wang Bao’s writing in 59 BC details the transplanting of seedlings at the Spring equinox. Later Chinese documentation shows the specific changes that growers brought to the fruit, from small, round, green fruit to the recognizable large, long-necked, purple-skinned fruits we know today.

Trade spread the seeds into Europe, where Spanish explorers brought them to the New World and by the early 1800s, both white and purple varieties were common in American gardens.

Eggplant Seeds

Site Needs

Eggplant is heat-loving, growing happiest in gardens with five months or more of warm to hot weather. Choose a sunny location where the sun can warm up the soil early. Raised beds and large black containers work wonders in colder climates to warm the soil sooner than in-ground gardens. Cool temperatures below 60°F reduce fruit production. In hot weather climates, afternoon shade can prevent leaf and fruit scalding, as fruit production decreases above 95°F.

Three to four plants will supply a steady stream of fresh delicately sweet fruit for a family, with extra for friends, neighbors, and co-workers.

Soil Needs

Like its tomato cousins, eggplant is a heavy feeder needing a rich, fertile soil to grow well and produce the best fruits. Adding well-aged compost into the bed the fall before planting provides nutrients all season. Fall cover crops improve the soil structure and fertility, as well as feeding the beneficial soil organisms doing the heavy work of transporting specific nutrients to the plant roots.

A plant growing in the dirt on a sunny day.
Eggplant Blossom

Planting

Soak the seeds overnight and plant in warm soil – ideally 80° to 85°F, but no less than 70°F – to greatly improve the germination rates. In warm soil, sprouts will appear in 7 to 12 days but can be delayed to three weeks or more in soil less than 70°F.

For almost all of North American gardeners, starting seeds indoors and transplanting them out after the soil warms up is the most successful method. Sow seeds indoors 6 to 8 weeks before your last expected frost date. Plant the seeds no deeper than twice their size in loose, moist soil then reduce the soil moisture to barely damp after the seedlings appear to reduce damping off and fungal issues. Transplant seedlings as needed into larger pots or containers to give the roots room to grow. Some gardeners will delay transplanting until a couple of weeks past last frost date to ensure bigger plants and earlier harvests, as well as avoiding early flea beetles.

Harden the young plants off by setting them outside on warmer days and bring them in the late afternoon,  helping them become more robust and ready for transplanting into the garden. Transplant after the soil is warming up and not dropping below 60°F at night. Measure the soil temperature first thing in the morning to see what the minimum is.

Give the plants enough room to grow with good air circulation – eggplant doesn’t thrive in an intensively planted setting. 2 to 3 feet between plants is a good distance, allowing the sun to reduce molds and mildew while ripening the fruits faster and more evenly. Adding a bit of well-aged compost into the transplant hole helps feed the plants.

A plant growing in the dirt on a sunny day.
Young Eggplant

Growing

Eggplant has a shallow root system, so avoid cultivating too closely and pull or clip weeds carefully to not disturb their roots. Better yet, use a 2 to 3-inch layer of mulch for weed suppression that also insulates the roots and soil from excessive moisture loss while keeping them cool in hot weather.

Bigger yields come from starting the plants early and transplanting big, robust, healthy starts into warm soil in a sunny area. Keep them warm with moist roots and pest-free, otherwise, they can be set back and have a difficult time recovering. Producing lots of fruit requires lots of nutrition, so feeding a diluted liquid fish emulsion, milk & molasses snack, or other organic liquid fertilizer once a month will keep the plants in tip-top condition and health.

Companion Planting

Companion planting is an excellent weed and pest control technique. An early season crop of lettuce, French parsley, or spinach followed by herbs like French tarragon, thyme, or Mexican marigolds. Beans and peas provide needed nitrogen and shade in hotter climates. In cooler climates, make sure the beans or peas don’t shade out the sun-loving eggplant.

One word of warning on companion planting beans and Mexican marigold – they are antagonistic, so don’t plant both with eggplant, choose one or the other!

Other nearby companion plants to consider are beneficial insect flower mixes to bring in ladybugs, lacewings, and others to keep aphids under control.

Mature Rosa Bianca Eggplant

Pests and Diseases

Colorado potato beetles can be a threat, but growing a companion crop of bush beans will help repel them. Inspect the undersides of leaves for the tell-tale yellow egg masses and pick them and any adult bugs off immediately.

Tomato worms can appear, so pick them off as you would on tomato plants. Knock aphids and red spiders off with a blast of water from the garden hose.

Flea beetles are the largest threat and can riddle young plants with tiny holes seemingly overnight. Small round holes in the leaves and tiny insects that jump like fleas are signs of flea beetles. In extreme infestations, the plants can lose their leaves and die. Young transplants are most susceptible and early detection is the key to preventing extensive damage.

From our personal experience, you can have very riddled leaves on your eggplant and still produce fruits. Do not give up hope, try to rid the plant of the beetles and give a little extra nutrition.

Trap crops of mustard planted near the area are helpful, as is interplanting with Daikon radishes to repel the flea beetles. If there is a sudden infestation, floating row covers and yellow sticky traps will help control the adult population.

Eggplant Shapes

Harvest

Fully mature fruit has a shiny, smooth skin and firm texture. If the skin is dull, has any wrinkles, or is not firm to the touch – it is over-ripe or old and will be bitter.

When harvesting, cut the stems with a sharp knife or shears, don’t twist or pull them off as that damages both the fruit and plant. Handle carefully as they are delicate and bruise easily.

Harvest can start once the fruit is about one third mature size and still be tasty. This is a saving grace in the fall when frost threatens, just pick the young ones and have one last feast of baby eggplant!

Flavor is at its absolute peak just after harvest, but they can usually be stored a day or two in a cool place before starting to turn bitter.

Fresh Mint Taste All Year

Lime and mint are not usually thought of together (if at all) in combination with pickles, but they should be! The lime-mint flavors work together with the cucumbers to make something much more than the sum of their parts – bright, refreshing, and absolutely addictively delicious.

Even after a year in the freezer the mint tastes fresh-picked.

Similar to our much-beloved Cilantro Freezer Pickles, this is a very simple and fast recipe that doesn’t need canning or heat and will handle any amount of surplus cucumbers – from a few up to way too many!

Each recipe makes about 4 pints, so you can expand accordingly.

Quick, easy, and addictively delicious, the lime and mint work with the cucumber to create something amazing. 

Course: Appetizer
Keyword: freezer pickles
Ingredients
  • 2 1/2 lbs pickling cucumbers thinly sliced
  • 3 tbs pickling salt Kosher salt works and tastes great
  • 1/2 cup mild onion thinly sliced
  • 1 small sweet pepper chopped
  • 1 lime zest grated
  • 2 cloves garlic minced
  • 1/4 cup fresh mint leaves minced
  • 1 1/2 cups sugar organic cane sugar gives a more rounded flavor
  • 1 1/2 cups white vinegar red wine or cider gives different flavors
Instructions
  1. Wash and thinly slice cucumbers – do not peel, then thinly slice onions.

    Toss cucumbers and onions in a large bowl with salt, mixing well to evenly distribute the salt. Let stand at room temperature for 2 – 3 hours, then drain excess liquid but do not rinse.

    Combine remaining ingredients in a separate bowl, mix well and pour over vegetables, stirring well to mix. Refrigerate for 8 – 10 hours or overnight. 

    Pack the vegetables and brine in freezer-proof rigid containers and freeze. Make sure to leave about 1 inch of headspace to allow for expansion so the jars don’t break.

    When packing the vegetables, make sure the brine completely covers them to prevent freezer burn and ensure the best flavors.

    Freeze for a minimum of 2 weeks to allow the flavors to mature and mingle.

    To serve, thaw overnight in the refrigerator and enjoy! 

Recipe Notes

We use a Cuisinart or similar kitchen appliance to slice the vegetables – reducing our prep time to a few minutes. 

Make the pickles according to the recipe, then experiment and use different ingredients to suit your tastes or the occasion. Try sweet onions, more pepper, lime, or mint for a more intense flavor. Different sugars have a different effect on the final flavor – try palm sugar, turbinado, or even a little brown sugar to the mix. Same with the vinegar – find which one you like best!

The salt draws out the natural juices, creating a brine to preserve the flavors.

After sitting, drain off the brine but do not rinse.

Combine the sweet pepper slices and remaining ingredients into a separate bowl, mix well, then pour over the brined vegetables and refrigerate overnight.

The next day, pack the vegetables into a freezer-proof container or bag. We like to use pint canning jars – just the perfect size for a family picnic or BBQ. If the gathering is larger, we take two.

When packing the jars or containers, just make sure to leave enough room for expansion so they don’t break or split the containers. Cover the vegetables with the pickling solution for the best flavor and to prevent freezer burn of exposed vegetables.

Freeze for at least 2 weeks for the flavors to mingle and mature before serving. Thaw in the refrigerator overnight and serve cold.
