Best Vegetables to Grow in the Shade

Even in shaded conditions, you can bask in great garden harvests if you choose the right crops and make a few easy adjustments.

For successful growing in the shade, remove low-hanging branches from nearby trees, use raised beds and liners to discourage tree roots from wicking water away from crops, and use reflective mulches to give plants more light.

For many gardeners, the optimum conditions most vegetables prefer — eight to 10 hours of full sun — just aren’t possible. Whether it’s from trees or shadows from nearby buildings, shade is commonly a fact of gardening life. Luckily, shade doesn’t have to prohibit gardeners from growing their own food. If you start with the most shade-tolerant crops, take extra care to provide fertile soil and ample water, and consider using a reflective plastic mulch, you can establish a productive shade garden and harvest a respectable variety of veggies.

How Much Shade Is Too Much?

All shade is not equal. Some shady conditions will yield much more produce than others will, while some areas are better left for hostas and moss. Gardeners should be familiar with the different types of shade, but should also keep in mind that measuring how much shade your garden gets isn’t always easy.

For instance, nearby trees may cast dappled shade on your garden for some or all of the day. If the tree canopy is high enough and the branches aren’t too dense, the conditions nearby can be shady but still fairly bright. Trimming any low-hanging branches can help let in more sunlight.

More challenging than dappled shade is partial shade, which can be quite variable, ranging from only a couple of sunny hours and many hours of shade to the opposite. Shade from buildings is more difficult to deal with than shade from trees, as it often plunges the garden into total shade for large parts of the day. As a general rule, if you have a few hours of full sun but dark shade for the rest of the day, you can grow some crops, but the yields won’t be as high as if you had bright or dappled shade during the rest of the day. Maybe your garden has a little of everything: some areas that get a couple of hours of sun, some that get dappled shade and some areas that are in complete shade. In addition, the amounts of shade will change seasonally! It can be difficult to add up the exact amount of sun your crops get in such a scenario. Keep an open mind about what you may be able to grow in your conditions, and use our chart of the best shade-tolerant vegetables as a guide for where to start.

Reflective Mulches and Surfaces

Reflective mulches, including metallic mulches, are a great tool for gardeners growing in shady conditions, and for some crops in some regions, the benefits can be huge. University studies have shown increased yields in crops such as peppers, tomatoes and strawberries.

Reflective mulches — such as the red plastic mulch some tomato growers have become fond of — reflect light up onto the leaves of plants. Mathieu Ngouajio, Associate Professor of Vegetable Crops in Michigan State University’s Department of Horticulture, says that under partial shading, reflective mulches have been shown to provide the following advantages: increased amount of light in the plant canopy, increased air temperature in the plant canopy, increased photosynthesis, reduced incidence of certain insects (particularly aphids and thrips), and increased produce yield and quality. Ngouajio recommends metallized reflective mulches (which look like aluminum foil) because they reflect the entire light spectrum and will have the greatest impact on increasing photosynthesis and, therefore, growth.

Creating other bright, reflective surfaces near your garden will also benefit plants. If you’re growing near a wall, R.J. Ruppenthal, who shares his experiences with his small, Bay Area garden in his book Fresh Food From Small Spaces, recommends painting the wall white or another light color.

“A bright-painted wall that faces the sun for any period of the day, particularly south-facing, will reflect an enormous amount of light and heat,” Ruppenthal says. “This speeds up growth rates quite a bit, and can compensate for some other shade during the day.”

We encourage you to try reflective mulches (aluminum foil should also work nicely) and reflective surfaces in your own shady garden. If you use them, let us know how they work out!

Soil Considerations

If you’re going to push the envelope sun-wise, make sure your soil is well-prepared. Amend your garden soil with plenty of mature compost, and loosen the soil to at least a foot before planting your crops.

The roots of nearby shade trees present a challenge all their own. The roots will wick moisture and nutrients away from your crops, causing them to need more frequent watering and fertilizing, and the roots will eventually invade your well-prepared soil. To overcome this, build raised beds or grow in containers filled with good-quality potting soil. If you’re building a raised bed, try lining the bottom of the bed with discarded carpet to help keep tree roots at bay.

Pests and Diseases in Shady Gardens

In any garden, the key to successful pest and disease management is to pay close attention to your plants and deal with problems right away. This is doubly important in shady gardens, where some disease problems can be exacerbated by the low light levels, and pests such as slugs and snails — which thrive in damp, shady conditions — can decimate your lettuce crop in a flash.

Check your garden daily for the first signs of pests. Chewed leaves are most likely from slugs or snails. Handpick these pests whenever you see them. Also, a reflective mulch brightening your garden will do double duty as a pest deterrent: The reflective surface will confuse many pests, and they’ll tend to avoid the area.

Trial and Error

Shade gardening experts tend to champion a trial-and-error approach to growing without full sun, all offering the same advice: Just try it and see! Some of the vegetables on our chart of Best Shade-Tolerant Vegetables will grow better in your conditions than others will. The quality of shade, your soil type and level of fertility, ambient temperature and how much moisture the plants get all play a role in determining the success of the crops.

Regional conditions also play a part in how well your garden will handle shade. In the South and at high altitudes, some shade can be a good thing during summer to protect plants from the intense sunlight. In cooler, less-sunny areas, such as the Pacific Northwest, growing in shade is a bigger challenge. Orientation can have an effect on the garden, too: North-facing slopes are already cool and shady, but south-facing slopes tend to be hot and dry during the summer. South-facing gardens benefit from a bit of shade to conserve moisture and regulate temperatures slightly.

Have a blast experimenting in your garden. Rather than feeling limited by less-than-perfect conditions, try to see shade as a fun challenge to overcome, and we’re betting you’ll eventually enjoy plenty of delicious, homegrown food!

I have a columnar table showing the plant, the amount and kind of sunlight, and a detailed explanation. Mouselink: Ooops, huh?

Some seriously angry hippies below. Just click the highlighted glue letters above that say "best shade-tolerant vegetables" and there is the list.

@mouselink

You are either blind or just ignorant, there are several links throughout the article that go to detailed tables about vegetable and crops that grow in the shade... obviously someone who just skimmed the article looking for a big bold list.

If you spent half the time reading the article as you did writing your rubbish below, you would have seen that.

Misleading article title, since the story never mentions any specific vegetables to plant. This negative exposure for your magazine will only lead to the resentment that you are being dishonest in order to gain traffic.

If you have a slug problem in the shade try this-I pick about a cup or two of slugs off my plants and and run them in the blender (don't tell my wife!) delute with a couple of cups of water and spray immediately on the foliage.I usually make a quart or so and it works every time.Haven't tried in on veggies and food crops thought....might be a problem! I would think it would be ok if you did it before flowering and fruiting occurred. Learned this trick from Organic Gardening mag back in the 60's. Works great. Not sure whether it kills them or just offends them and they leave! Either way.........

@Radical Mama, I was looking for the same thing! It's there, but listed as a clickable link on the third page right beneath the Trial and Error section of the article.

I have had good luck with red and purple potatoes in the shade. They do not produce in commercial amounts, but I don't need commercial amounts. The flowers are pretty, and if there is not enough water, the tops just die back. Pansies, strawberries, and garlic may do all right as well. Blueberries are a bit fussy some years, but the harvest just gets drawn out to winter. I still have berries when people with better conditions are done.

did i read this wrong or, do they never get around to telling you what grows best in shade? they list growing conditions and passively mention some crops while discussing mechanical methods of encouraging growth, no list though. new title would be appreciated. sometimes i wonder about this mag........

I put aluminum foil around the base of tomatoes I grow in containers--not only do I like to imagine it reflects light, but I think it confuses the groundhogs! :)
