Introduction to shade vegetable gardening: Shade vegetable gardens are planted and grown in areas with little or no direct sunlight. Shade, due to trees or buildings, is an almost inevitable part of gardening. There are several vegetables that grow in shade.
A step by step guide to shade vegetable gardening ideas
Trees and buildings in and around your yard can make it difficult to select a garden location. The shadows cast by objects change throughout the day and the season as the sun shifts. Luckily, there are several edible plants that can thrive in partial shade, dappled shade, or in as little as 3-6 hours of sunlight a day. We will be discussing today mostly about vegetables that grow in full shade, vegetables that grow in partial shade, deep shade vegetables, shade vegetables list, and edible plants that grow in full shade.
Partially shaded places can give a perfect microclimate for vegetables that prefer to avoid the strong midday sunshine of summer. There are plenty of vegetables that grow in shade, dappled sunlight, or with as little as 3 to 6 hours of sunlight per day:
Understanding sun exposure for vegetable garden
There are some basic sunlight conditions that are mainly used to describe the amount of sun during the prime-growing season;
Full sun areas receive direct sunshine for about 6 or more hours per day between the hours of 10 am and 6 pm. Plants requiring full sun do better with 8 or more hours per day. More than 6 hours of direct sun per day at midsummer.
Partial shade or partial sun both refer to areas that obtain 3 to 6 hours of sun each day. Partial sun areas receive 3 to 6 hours of direct sunlight but are shaded for the rest of the day. Partially shaded spaces are moderately shaded during part of the day or dappled sunlight all day. Dappled sunlight is where the light is filtered through the leaves of plants.
Full shade areas could receive no direct sun or reflected light during the day. An area with deep shade is not a good place for growing vegetable plants. All plants require some light to grow.
Maximize the potential of shade vegetable gardening
Even shady gardens will receive at least a couple of hours of sunshine a day. The secret to coping with shade is to create the most of these windows of direct sunlight.
In most climates seedlings need as much light as possible in order to start off strongly, so prioritize the sunniest parts of the garden for seedlings. Plants grown in pots and module trays within cold frames, or start seedlings off in a seedbed then transplant them to another part of the garden. If you are starting vegetable plant seeds early in the season, using full-spectrum grow-lights indoors.
Make the most of obtainable light by reflecting it into shadier parts of the garden. Paint walls and fences white and other reflective surfaces that are shiny metal or foil to bounce light back into these darker areas. It is important to remember that shadier corners will be slower to warm up in the spring, use cold frames, cloches and horticultural fleece to warm up the soil earlier. They can be used to extend the growing season later on in the fall.

Growing your vegetables in the shade
Vegetable plants that are grown in shade houses are most likely to be succulent and free of the bitter taste. To effectively grow vegetable plants in a shade house, look for areas that receive sunlight above ground level. Areas that are shaded in the morning but sunny by afternoon are great for climbing vegetables like beans, peas, and cucumbers.
Use good soil – If you are going to challenge your shade-tolerant plants to grow in partial shade, provide them with good-quality soil with plenty of nutritious compost. If tree roots are a problem, consider using a raised bed or growing vegetable plants in containers.
Moisture requirements – The watering needs of the shade garden will be different than a garden in full sun. However, if your shade garden is near trees, you can need to water more frequently since your plants will be competing with trees for moisture. Water the plants when the soil feels dry and mulch to conserve moisture.
Selecting plants for shade vegetable gardening
Choosing vegetable plants to grow in shady sites is not much different than selecting them for the full sun because the major concerns still apply. Some important considerations include landscape size, desirable and undesirable characteristics, pest resistance, hardiness, and cultural and maintenance requirements. Some vegetable plants require full sun (at least 8 hours of direct sun a day) and some prefer full sun but will tolerate some shade. Still, others are genetically engineered to require shade. Their leaves can be thicker and darker and will sunburn or scald if exposed to direct sun, especially in midsummer and mid-winter.
Some of the vegetable plants in shade
Beetroot, carrots, chard, kale, kohl rabi, leaf salads, lettuce, peas, runner beans, and spinach are relatively tolerant of light shade. Sowing plant seeds in modules in bright conditions and transplanting will get them off to an early start with an established root system.
Vegetable plants grown for their leaves and roots are the best choices for shady gardens. Salad greens that are lettuce, spinach, cabbage, and celery can be grown in shaded gardens. Roots crops such as beets, leeks, potatoes, and turnips could be grown in shady gardens.
Vegetables plants that will grow in light to partial shade are arugula, beets, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, celery, chard, Chinese cabbage, corn salad, endive, escarole, garlic, horseradish, kale, kohlrabi, leaf lettuce, leeks, mustard, parsnips, peas, potatoes, radishes, rutabagas, salsify scallion, sorrel, spinach, turnips, and watercress.
Vegetables that thrive in partial shade
Arugula, endive, watercress – These greens welcome shade as they tend to bolt and bitter in too much sun or heat. These plants require 3-4 hours of sun per day. For salad greens that are almost effortless to grow, prefer arugula. The spicy leaves produce rapidly, even in the shade. Arugula tolerates nearly any type of soil but it requires frequent watering to maintain even moisture levels.
Chard – This plant requires 3-5 hours of sun per day. Though the plants will be smaller than they would be if grown in full sun, they will still make plenty of tender greens when grown in partial shade.
Cabbage and Brussels sprouts – Brussels sprouts are a cold-tolerant plant, and like cool-weather plants, they do well with limited sunlight. Though cabbage is broad-leafed, too much sun will dry it out and encourage smaller heads and bigger open leaves.

Lettuce – Lettuce requires a minimum of 3-4 hour sun exposure. Again, shade is actually useful in this scenario as lettuce tends to bolt when the heat comes on. Partial shade could actually extend the harvesting life of your lettuce by 2 or 3 weeks, if not longer. Lettuce thrives in cool weather and does better in the shade, particularly when temperatures start to rise. Full sun can increase the chances of premature bolting, so selecting a semi-shaded spot is ideal for summer lettuce.
Spinach – Exposure to full sun will often slow spinach growth to a crawl and encourages super-premature bolting. These cool-season vegetable plants grow best in loamy soil with a neutral pH. Water consistently to plants and avoid letting the soil dry out. Spinach requires 3-4 hours of sun per day. Another early bolter, best grown both early and late in the season as spinach doesn’t seem to be able to produce much before bolting in the heat of mid-season.
Kale – Every garden must be growing kale. It is nutritious, tasty, and handles a range of temperatures with ease. While it prefers full sun, it’s capable of leafing out in partial shade. This kale plant requires fertile soil with a loamy consistency.
Green onions (scallions) – Green onions require more than 3 hours of sun per day. These green onions will do well in the partial shade all season long.
Peas – Peas are one of the first spring vegetables to be sown in many gardens, and they grow in full sun or partial shade. Peas plant in soil that’s been amended with compost and water occasionally.
Potatoes – While full sun is recommended for growing potatoes and harvested tubers after a season of growing in partial shade. Grow taters in acidic, sandy soil, and ensure they get regular watering.

Broccoli and Cauliflower – Full sun on broccoli plant can cause rapid flowering (which ruins the taste), while partial sun encourages tighter heads and slower flowering. With cauliflower, limiting sunlight to less than 6 hours daily means tighter heads of cauliflower.
Gardening tips for growing vegetable plants in shade
Here are some useful tips to grow vegetable plants in a shade.
- Use good soil with nutritious compost when growing your vegetable plants in the shade house.
- Since you are growing your vegetable plant in the shade house, watering requirements may be different than growing plants in full sun. Thus, you may not need to water vegetables as often because moisture doesn’t evaporate too quickly in the shade house.
- Choose vegetables adapted to shade; don’t try to grow crops that demand full sun.
- Start plants for shady gardens indoors to speed harvest; germination and early seedling growth can begin under optimal conditions before transplanting to the shady site.
- Expect slower maturation of plants and scale down expectations of size and yield.
- Painting nearby walls or fences white will allow more light to bounce into the shade vegetable garden. Light-colored paving on driveways adjacent to the shaded gardens will reflect more light. Grow vegetable plants in containers so that they can be moved into sunny spots as the season’s change.
- Check shade garden regularly for pests such as slugs and snails which can thrive in shady areas. You must practice good sanitation process to avoid pest problems.
- You can utilize reflective mulches to cast light up onto plants. Reflective mulches can reduce damages that are caused by pests.
Advantages of a shaded vegetable garden
- Vegetable plants grown in semi-shaded conditions commonly require less water and fertilizer. They can tolerate longer periods between watering.
- A shaded microclimate reduces moisture loss, so vegetable plants are less inclined to wilt and suffer heat stress.
- Soil is less likely to dry out as quickly, mainly if you protect it with mulch.
- You can often extend the harvest, as many varieties won’t bolt to seed as quickly with relief from hot sun and shade relief may buy you time.
- By utilizing your shady microclimate zones efficiently to grow food, rather than wasting these spaces, your garden can become more productive. Try sowing in between larger plants, amongst ornamentals or hanging baskets under trees.
Pests and diseases in shady vegetable gardens
Shady and cool areas are welcoming to slugs and snails. Consider using a border of crushed eggshells to deter slugs or give a hospitable living area to attract frogs and toads to your Garden. In any garden, the key to successful pest and disease management is to pay close attention to your vegetable plants and deal with problems right away. This is doubly important in shady vegetable 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 that can decimate your lettuce crop in a flash.
Check your vegetable garden daily for the first signs of pests. Chewed leaves are most likely from slugs or also snails. Also, reflective mulch brightening your vegetable garden will do double duty as a pest deterrent. The reflective surface will confuse many pests, and they will tend to avoid the area.
