Shade Your Garden for Better Vegetables

Peppers and Tomatoes Love a Little Shade

Shade for a garden is a polarizing subject – it seems like we’ve either got too much or too little. Today we’re focusing on gardens that need some shelter – the ones with perpetual sun-scaldon tomatoes and peppers or cilantro that bolts almost immediately after sprouting.

Shading a garden often seems overwhelming, especially if you live in the very sunny zones of the US, Canada, Australia, or in other bright parts of the world, but it shouldn’t be complicated or expensive. Today we focus on simple and easy methods for giving your garden some relief – exactly where and when it is needed.

Vegetables like tomatoes, peppers – both sweet and hot, eggplant, lettuce, spinach, along with herbs like cilantro, all benefit from a little shade, especially in the sunny, hotter afternoons of mid to late spring through late summer or even early fall.

Full sun in the early to late morning gives plants plenty of energy through photosynthesis without excess heat stress, allowing them to grow and produce to their full potential. Providing afternoon shelter relieves a lot of the heat buildup, lowering the amount of moisture lost through leaves and the need for extra water to keep the plant healthy. This allows the plant to spend its energy on growing delicious fruits and vegetables, not in transporting water from the soil just trying to stay alive. We talk more about this specifically for peppers in Grow Better Peppers with Shade.

Defining Shade

Now that you know why shade is beneficial for a sunny garden, what – exactly – is shade? Let’s look at the different types of shade through commonly used terms.

Deep Shade – there is no direct sunlight at all and only a small amount of reflected light, such as from the wall of a light-colored house, garage or fences. This would be under the canopy of several large, fully mature trees.

Light Shade– gets only one to two hours of direct sunlight a day, but has quite a bit of reflected light from nearby walls and fences. Most likely underneath large trees, but has either morning or afternoon sun reaching the ground.

Partial Shade– sees direct sunlight for two to six hours per day with dappled shade the rest of the day. This would be from less mature trees, a fewer number of trees close together or those without an extensive leaf structure.

Full Sun – receives at least six hours of sunlight per day but more likely eight to ten hours. This could be shorter or younger trees, wider spaced plantings, or species with smaller leaves and less shade structure, such as elms as compared to oaks.

Use this information as you plan on what varieties to plant where.

Morning vs Afternoon Shade

When do your plants need some shelter? Typically during the hottest parts of the day – afternoons – during the hottest parts of the year – May or June through August or September. The exceptions are the areas routinely above 110Â°F like Phoenix, Tucson, Las Vegas, and Palm Springs – they grow better with mid to late morning shading lasting all afternoon. For the rest of us, if our plants start seeing some shadows by about 1 pm, they are comfortable and produce nicely.

What this means is that permanent overhead shade structures are usually not needed. They can be a nice addition if part of the structure is over a picnic table or BBQ area next to your garden, but the garden doesn’t always need that much cover for that long.

The upside to temporary shade for part of the day is it can be removed for cool weather crops needing as much sun as possible to capture the warmth on the soil to grow earlier or later in the season.

East vs West Shade

Where is the best place for your shade? Most plants need some afternoon protection, meaning the shadows should come from the west side of your plants, or that you plant on the east side of the protection. Confused? Don’t be – think of it this way. As the sun moves to the west, it casts shadows to the east and that’s where you want your plants to be – in the shadows!

In the photo above, the Achocha is growing on the west wall of this courtyard and has afternoon protection – this photo was taken about 11 am, with full morning sun. After about 1 pm, the shadows arrive and the area cools down, even though it reaches 100Â°F or more each afternoon during the summer. When we first tried growing it on the east wall, it received morning protection but was baked in the afternoon’s direct sun, struggling to grow and not producing any fruits. The fruit production exploded and it was much happier once we moved it!

Southern Shade

Beyond east/west shade, you might consider giving your garden protection to the south. Shading a section of your garden along the south fence with each row having its own screening on the west side gives more sensitive plants extra protection from the sun.

Wind moderation is another advantage of shading, as each successive row slows down the prevailing breeze, making the growing conditions more favorable. Plant hardier plants upwind and less wind tolerant ones downwind.

Commercial shade structure

Adding Shade to Your Garden

Giving your plants some much-needed sun shelter can be easier than you might think. Here are some examples to get you thinking about your garden and how it is set up.

Permanent structures

This is what everyone seems to think about first when talking about shading a garden. The commercial type shade structure, supported by big square steel poles with the whole garden shaded is one approach.

Another is simply planting in containers on the east side of your house or garage. This is exactly how our container garden is set up, starting right next to the east wall and stretching out for about 10 feet. It gets full morning sun and starts seeing shade in the early afternoon, and by the hottest part of the day it’s in light shade – no direct sun and only reflected light. We’ve grown cilantro in the container closest to the house almost all summer without it bolting.

Yet another is a chain-link fence with privacy strips woven into it, either 6 or 8 feet tall. Some houses already have these as a border fence and all you need to do is add the privacy weave. A tall wooden fence gives you built-in shading.

Temporary structures

These are the most common types of non-living sun screen, easily put up and taken down as needed. One example is shade cloth zip-tied to the south fence of a garden, providing both shade and wind filtering. The amount of shade depends on the height of the fence.

Another is the T-post and shade cloth approach. 8-foot tall T-posts are pounded in on the west edge of the row or bed at 4 to 6-foot intervals, then shade cloth is zip-tied to them. This gives about a 7-foot tall shade wall, as the T-posts are driven in about a foot deep, giving a good shade and windbreak for vegetables. Removal is easy when fall approaches and the sun is needed all day.

Another example is a hoop house made from semi-rigid 20-foot long cattle panels arched over a bed or couple of rows and covered in shade cloth or clear plastic as needed. The plastic makes the hoop house into a large cold frame early in the season for lettuce, spinach, Swiss chard, and other cold-season greens, then is switched for shade cloth when tomatoes, peppers, and eggplant are transplanted in early spring. The plastic is re-installed in the fall for another season of cold-season crops before winter.

Living structures

These can be either temporary – as in a wall of Russian sunflowers on the south fence, or more permanent – like a large trellis or hoop house made from cattle fencing panels as above and planted with a vining, leafy vegetable that crawls up and shades the entire area. The trellis is permanently installed, while the vines are replanted. A planting of okra along a fence, as the photo above shows.

Now it’s your turn

3 Ways to Grow Great Onions from Seed

Why Grow Onions from Seed?

Many gardeners begin growing their onions from transplants or bulbs bought at their local garden center. They are convenient, easy to grow and a great way to learn about growing delicious onions in your garden, but they have some drawbacks. Like tomatoes and peppers, the selection is limited to what the grower chooses and freshness isn’t always a given.

Growing onions from seed opens up a world of diversity in shapes, sizes, flavors, and colors to grow. Starting from seed typically rewards you with bigger and better quality onions, with larger harvests being a bonus from the abundance of seed in a packet.

Onions grown from seed almost always perform better than those grown from sets. They are less prone to disease, store better, and bulb up faster, especially if you have some knowledge and tips to do it right. Growing onions isn’t quite like growing other vegetables, so here’s how you can grow better this season!

Types of Onions – Long Day vs Short Day vs Intermediate Day

Long vs Short Day Onion Zones

Which onion varieties are best for you depends on where your garden is located. There are three different types of onions and picking the right type is key to growing a great crop.

Short-day onions need 10 – 12 hours of daylight to form bulbs. They’re perfect for gardeners in the southern US where summer days are not as long throughout the growing season. Growing short-day onions in the north results in tiny bulbs that go to flower early because the bulbs stop growing once the days lengthen.

Long-day onions need at least 14 hours of daylight to form bulbs. They’re best for gardeners in the northern tier of the U.S. and Canada. Just like growing short-day onions in the north, long-day onions won’t form bulbs in the south because the days aren’t long enough to trigger bulb formation and you wind up with small bulbs or bunching onions.

Intermediate Day Onion Zone

Intermediate-day onions form bulbs when the daylight ranges from 12 – 14 hours long. If you live somewhere across the mid-section of the US, day-neutral or intermediate onion varieties are the best fit.

Three Ways to Grow Onions From Seed

There are three distinct ways to grow your onions from seed and the best way for you depends on your particular gardening style, equipment and available time. Onions grow best in loose, fertile soil that drains well.

1- Direct Sowing in the Garden

The simplest method is direct to sow your onion seeds directly into the garden soil. Before sowing, refer to the garden bed preparation section below. Draw a line down the middle of the bed about 1/8 – 1/4 inch deep and sow the onion seeds with about 3-inch spacing to avoid crowding. Lightly cover the seeds and dampen well. Onion seeds will tolerate a light frost.

The pros of this method are its simplicity – sow your onions once, then harvest when ready. No transplanting for you!

The cons are making sure you plant the seeds early enough for the bulbs to develop by mid to late fall. You also have to deal with weather events and being able to possibly protect the seedlings if there is hail or heavy rains. Most northern states don’t have a long enough season to support direct seeding.

The good news is experimenting is inexpensive – a packet of onion seeds will set you back a grand total of anywhere from $3.15 to $3.35, and you get about 500 seeds to work with. You’ll also invest a little bit of your time in learning what works best for your garden.

2- Starting in Trays

Starting your onion seeds in trays requires a small amount of equipment or conditions and some time on your part. You’ll need a tray to catch the excess moisture and either a flat with cells or individual pots such as peat pots, paper pots, or similar filled with a high-quality pre-moistened seed starting mix. If you aren’t sure which mix works well, read our Seed Starting Mix article. You can also use a container about 3 – 4 inches deep and fill it almost to the top instead of pots or flats. Used berry or take-out containers work well with holes poked in the bottom and lid. Start your seeds about 10-12 weeks before transplanting date, which is about 2-4 weeks before your last frost date.

Plant the seeds by placing 2 seeds per cell or pot and covering with about 1/8 inch of soil. If you are using the container method, scatter the seeds on top of well-moistened potting soil then cover with the 1/8 inch of additional soil. Label the containers or flats, place in the catch tray and cover with a humidity dome or lid. Place on a heat mat, heating pad, or warm area where it’s a constant 70-75Â°F. Once the seeds start sprouting – about a week – remove the humidity dome and move to a cooler area, about 60-65Â°F. Give them plenty of supplemental light with a grow light or other fixture for about 12 hours per day. Trim the tops back when they are about 5 inches tall to encourage stronger root and stalk growth.

Onions will tolerate cool spring temperatures but must be acclimated first – a process called hardening off. Start about 6 weeks before your last expected frost date (look yours up here) by giving them exposure to natural sunlight, cooler temperatures, and a less moist soil environment. Begin by placing the tray in a sheltered location outside during the day for an hour or two, increasing a little each day until they are outside from morning until night time. Onion seedlings will tolerate a light frost, so don’t worry if you get a late-season cold snap!

They are now ready for transplanting, and you should be about 2 weeks before your last expected frost date. Before transplanting, refer to the garden bed preparation section below. To transplant, remove the soil blocks or gently dump the tray out, then tease the seedlings out of the potting soil into clumps of no more than 2, placing them 3-4 inches apart next to the furrow. Stage or pre-place all of the transplants before planting them to save time and your back!

Using a dibber or other similar tool, poke a hole into the furrow about 3-4 inches deep and drop each clump in – don’t worry, this isn’t too deep! Gently firm the soil around the transplant and keep the beds well watered and weeded until the onions are well established.

The pros for this approach is you know exactly where your onions are, as you can see the green tops sticking out. You can also select the strongest seedlings to transplant, creating a better chance of a good harvest.

The cons are that seedlings will have some transplant shock and you’ll lose some – grow extra transplants to fill in the gaps. Young, tender greens are snacks for all sorts of critters in early spring, so you may need to provide some protective cover until they are more established.

3- Winter Sowing

This is perhaps the second easiest option as it takes little time on your part and almost no equipment. Winter sowing is basically cold-stratifying your onion seeds to the outside temperatures, then they sprout when conditions are right in the spring. You can plant your seeds this way anytime from early December to mid-February in most locations.

Seed sowing is similar to starting seeds in a container, except you skip the heat mats, grow lights and all of the other equipment. Start with a container that has some holes in the bottom for drainage, fill to within an inch of the top with good quality dry potting soil and sow your onion seeds across the top with a sprinkling motion, giving them about 1/4 to 1/2 inch spacing. Poke 1/4 inch holes in the lid for ventilation and put it on the container after labeling it with the date and type of onion you planted.

Now place the container in a shady, protected spot outside. It doesn’t matter if it freezes or snows – the onion seeds are acclimating to the changing conditions and will remain dormant until the conditions are right. This is why you use dry potting soil!

When the temperatures and day length are right, your onion seeds will start sprouting inside the container. As the weather starts to warm up during the day, check your seed container every couple of days for signs of sprouting. Once you see the tiny bits of green peeking out, then you’ll need to water the potting soil, keeping it slightly moist but not wet. As they grow, open the lid on warm days and close it at night, still keeping it out of direct sun. If you get a hard freeze once the seedlings have germinated, cover the container with a blanket or towel at night to protect them, but remove it next morning.

As soon as you can work your garden soil in early spring, transplant your seedlings just like if you had started them indoors. Before transplanting, refer to the garden bed preparation section below.You don’t need to harden them off because they’ve been outside all winter and are acclimated to the temperatures.

The pros to this method are the plants are used to the natural temperature and light cycles and are primed to germinate at the right time. They usually form larger bulbs more consistently as well.

The cons are remembering to check on the container that might be out of sight outside, especially when the temperatures warm up.

Growing Bed Preparation Before Sowing or Transplanting

Prepare your garden bed for either sowing or transplanting before you need it to save time, back strain and headache. The basics are the same -dig a furrow about 4 inches wide and deep, then fill it with rich, well-aged compost. It’s best to do this in the fall before the ground is too hard, but it can be done in early spring as soon as the ground can be worked.

Onion Growing Tips

Start with fresh seed and seed starting or potting soil mix each year. Onion seed germination decreases after the first year, so why chance it? Fresh mix minimizes the chance of diseases during the long germination and seedling periods.

If starting inside, bottom heat really speeds seed germination up. 70-75Â°F soil temperature can create sprouts in about a week, versus 2 or 3 weeks at cooler temperatures.

Feed only the onion roots – just underneath the onion itself. They have short, shallow roots and can’t reach far, so provide the rich, well-aged compost where they can use it best.

Onions don’t compete with weeds very well because of their slow growth and small root structures. Weeds will significantly reduce your onion harvest, but there are better ways to fight weeds than weeding.Minimize weeding by mulching heavily between seedlings after transplanting.

Water onions efficiently with a drip system or soaker hose placed right next to the plants – remember their short roots. Doing this minimizes the amount of water they need, as well as reducing available water to potential weeds.
