What Vegetables Grow All Winter?
While many types of vegetables can be cultivated in winter, root vegetables and leafy greens are the true standouts of the season. These include root crops like beets, carrots, radishes, and turnips, as well as leafy greens like spinach, kale, collards, and Swiss chard.
Both root vegetables and leafy greens have a natural resistance to cold. Root vegetables’ edible parts grow underground, offering them insulation from the colder air above. Leafy greens, on the other hand, have evolved to withstand frost. Some can even survive under a blanket of snow and continue to grow when temperatures rise again.
The concept of container gardening during winter might seem unconventional, but it comes with some advantages that can revolutionize your gardening journey. Please be sure to read my complete guide to winter container gardening so that you are prepared.
Embracing container gardening opens up a world of possibilities, breaking down the barriers of seasons and space. It’s your ticket to year-round fresh, home-grown vegetables, and the joy of gardening, no matter the weather outside.
15 Best Winter Vegetables To Grow In Pots
Beets
Often prized for their deep, vibrant hue, beets bring a welcome pop of color to the winter garden. They’re not only visually appealing but also packed with health benefits, making them a worthy addition to your container garden.
Beets thrive in deep containers (10-12 inches) with loose, well-draining potting mix. Plant the seeds directly into the pot 1 to 2 inches apart and ½ inch deep, and make sure they get 4-6 hours of sunlight daily.
Beets require consistent watering but avoid overwatering to prevent root rot. In winter, growth is slower, so patience is needed. They’re ready to harvest when the tops are visible at the soil surface. The best time to plant beets for a winter harvest is in late summer or early fall, depending on your local climate.
Carrots
Carrots are a versatile root vegetable that’s as fun to grow as it is to eat. Their satisfying crunch and sweet flavor make them a favorite in many dishes, and they’re rich in essential nutrients too.
For growing carrots, selecting the right variety for your pot depth is crucial. Shorter varieties like ‘Paris Market’ or ‘Short ‘n Sweet’ are suitable for shallower pots, while longer types like ‘Autumn King’ need deeper containers.
Carrots appreciate a fine, stone-free, sandy soil that allows their roots to grow long and straight. If your soil is heavy or clay-like, opt for shorter varieties that are better adapted to these conditions.
Carrots can be slower to grow in winter, but the colder weather can enhance their sweetness. Check if they’re ready to harvest by brushing away a little soil from the top of the root. If it looks big enough, gently pull it out, or use a fork to ease it out if it resists.
Carrots can be sown in late summer for a winter harvest. However, be aware that germination can be slower in colder temperatures, so it’s worth covering the pots with cloths or lids until the seedlings appear.
Celery
Celery may be a bit more challenging to grow than some other vegetables, but with a little care, you can enjoy its fresh, crisp stalks right from your container garden.
For celery, choose a deep pot—around 10-12 inches deep—to accommodate its long roots. Celery prefers rich, fertile soil with excellent drainage, so consider adding some compost or well-rotted manure to your potting mix for best results.
Plant celery seeds about ¼ inch deep. Celery seeds are tiny, so it’s okay if you can’t space them out perfectly. Once the plants are about 2 inches tall, thin them out to about 6 inches apart.
Celery loves water, so make sure to keep the soil consistently moist. Mulching around your plants can help retain moisture. Celery also needs a good amount of sunlight, so aim for 6 hours per day if possible.
Plant your celery in late summer for a winter harvest. It can handle frost, but if temperatures dip below freezing, you might want to bring your pots inside or provide some form of cover.
Lettuce
Lettuce is a fast-growing, cool-weather crop that’s perfect for container gardening. With its array of colors and textures, it not only provides fresh salads throughout the colder months but also offers aesthetic appeal to your balcony or patio garden.
There are many types of lettuce suitable for container gardening, including leaf lettuce (like ‘Oakleaf’ or ‘Salad Bowl’), butterhead (like ‘Buttercrunch’), and romaine (like ‘Little Caesar’). These varieties tend to mature quickly and are perfect for successive planting.
One of the benefits of lettuce is that you can start harvesting leaves when they’re young. This “cut-and-come-again” method ensures you have fresh lettuce over an extended period. Plant new seeds every 2-3 weeks for a continuous supply.
While lettuce does like sunlight, it doesn’t require as much as some other vegetables. Aim for 4-6 hours of sunlight daily. Keep the soil consistently moist, as lettuce thrives in damp (but not soggy) conditions.
Tomatoes
Tomatoes are perhaps one of the most beloved garden staples, boasting a rich taste that far surpasses store-bought varieties. When grown in pots, these vibrant fruits can be nurtured even when ground space is limited, and with specific varieties, they can be encouraged throughout the cooler months.
For cooler months and container gardening, opt for smaller, faster-maturing tomato container varieties like ‘Tumbling Tom’, ‘Tiny Tim’, or ‘Balcony’. These are designed for compact growth and quicker harvests.
If you’re attempting to grow tomatoes in cooler months, be vigilant about frost. Cover them or bring them inside if frost is predicted.
Broccoli
Broccoli is a cool-season crop that can be quite satisfying to grow. Its bright green heads bring a pop of color to the winter garden, and it’s a nutritious addition to your kitchen as well.
When growing broccoli in containers, consider choosing compact varieties like ‘De Cicco’ or ‘Calabrese’, which are more suited to pot culture. For standard varieties, choose pots that are at least 18 inches deep and equally as wide to give broccoli’s large root system enough room.
Broccoli requires full sunlight, with at least 6 hours daily. Consistent watering is essential; keep the soil evenly moist, but avoid waterlogged conditions. The restricted space of a pot means moisture levels need more attention.
In containers, it’s crucial to monitor for pests like aphids or caterpillars. Check the undersides of leaves and act quickly if you notice any infestation.
Bunching Onions (Green Onions or Scallions)
Bunching onions are a versatile vegetable, offering a mild flavor that can be used in a variety of dishes. Growing them in containers can be a rewarding endeavor, providing fresh produce in a compact space.
For container gardening, varieties like ‘White Lisbon’ or ‘Ishikura’ are excellent choices due to their compact nature and adaptability to pot growth.
Start sowing your bunching onion seeds in containers from late summer to early fall. This allows them to establish a good root system before the temperatures drop significantly. Depending on your region, this usually means planting 8-10 weeks before the first expected frost.
Bunching onions are hardy and can handle light frosts. However, during severe frosts or prolonged cold periods, consider using protective measures such as cloth covers or relocating your containers.
Cabbage
Cabbage is a cool-season crop that’s well-suited for winter cultivation, especially in containers. It’s a hearty vegetable, able to withstand frosty conditions, making it ideal for those looking to extend their gardening season.
For a winter harvest, sow cabbage seeds or transplant young cabbage plants into containers during late summer to early fall. This timing allows them to grow robustly before the colder winter temperatures set in. In general, aim to plant them 6-8 weeks before the first expected frost.
Choose a spot for your cabbage containers that receives ample sunlight, ideally 6-8 hours daily. As winter approaches, the amount of daylight decreases, so maximizing exposure is crucial.
In the event of a severe frost or snow, consider relocating your containers to a more protected area. Even though cabbage is frost-tolerant, a thick layer of mulch can be added on top of the soil to insulate the plant further during very cold periods.
Cabbages are renowned for their cold resilience. Mild frosts can enhance their flavor, making the leaves sweeter.
Potatoes
Potatoes, typically considered a staple in many diets, can be grown in containers for a winter harvest. While they generally prefer cooler weather over the scorching heat of summer, winter cultivation requires some special considerations.
To get a winter harvest, plant your seed potatoes in containers during the late summer to early fall. This gives them enough time to develop before the harshest winter conditions. If you’re aiming for smaller, “new” potatoes, you can harvest earlier; for fully mature potatoes, you’ll need to wait a bit longer.
Place your potato containers in an area that gets a minimum of 6 hours of sunlight daily. Even during winter, potatoes need adequate sunlight to grow. Due to their susceptibility to frost, especially when young, you’ll need to be vigilant. If frost is forecasted, consider moving your containers to a garage or shed overnight or covering them with frost cloth.
While mature potato plants can handle light frost, the tubers beneath the soil are vulnerable if the soil freezes. If the soil in your containers does freeze, the potatoes can become damaged or rot. It’s vital during extreme cold snaps to protect your containers, either by moving them indoors or insulating them.
Peas
Peas are a delightful vegetable, often heralded as one of the first harbingers of spring. Their sweet flavor and crunchy texture make them a favorite among gardeners. While traditionally planted in early spring, they can also be grown in winter in milder climates or with appropriate protection.
To enjoy a winter harvest or early spring yield, plant pea seeds in containers during the late summer or early fall. This provides them enough time to germinate and grow before the coldest weather hits. Aim to sow seeds 8-10 weeks before the expected first frost.
Peas are reasonably frost-tolerant. They can survive light frosts, and cold snaps can even improve their flavor by turning starches into sugars. However, prolonged exposure to heavy frosts can damage the plant, especially younger seedlings.
Cauliflower
Cauliflower, with its unique texture and subtle flavor, is a popular vegetable in many dishes. While it does require a bit more attention than some other crops, the reward of harvesting your own cauliflower head is well worth the effort.
Start by sowing cauliflower seeds indoors during late summer. Once the seedlings are strong enough (typically having 2-3 true leaves), transplant them to containers in early to mid-fall. This gives them ample time to grow before the colder temperatures set in.
When the cauliflower head starts to form and is visible but still small (about 2-3 inches in diameter), it’s time to blanch. This involves covering the head with its own leaves to protect it from the sun, which helps maintain its white color. Use rubber bands or soft twine to tie the leaves over the head.
While cauliflower plants can tolerate light frost, heavy frost can damage the plant, especially the developing head. If freezing temperatures are expected, consider moving the container to a sheltered location or use frost cloth for protection.
Brussels Sprouts
Brussels sprouts, resembling mini cabbages growing on a stalk, are a nutrient-rich vegetable that has become increasingly popular due to their distinctive taste and versatility in dishes. When grown in the cold, they often develop a sweeter flavor, making winter cultivation especially rewarding.
Start by sowing Brussels sprouts seeds indoors during late summer. Once the seedlings have grown strong and sturdy, typically with several sets of true leaves, transplant them to containers in early to mid-fall. This ensures they have a robust growth period before the deep winter cold sets in.
Brussels sprouts are exceptionally frost-tolerant and can even benefit from a light frost, which can enhance their flavor. However, in regions with severe frosts or snow, consider providing some protection using frost cloths or relocating containers to a more sheltered spot.
Given their height, Brussels sprouts plants can become top-heavy, especially when loaded with sprouts. Using stakes or small supports can help keep the plant upright and prevent it from toppling over.
Spinach
Spinach, known for its nutrient-dense leaves, is a favorite among gardeners for its rapid growth and adaptability to colder temperatures. Its tender leaves can be enjoyed in salads, smoothies, and cooked dishes, providing a continuous harvest during the winter months.
Spinach seeds can be sown directly into containers from late summer to early fall. Due to its fast growth rate, it can also be sown intermittently for successive harvests throughout the winter.
Ensure your containers are positioned where they can receive at least 4-6 hours of sunlight daily. While spinach can tolerate some shade, especially in cooler weather, it thrives best with adequate sunlight.
One of the best things about spinach is its “cut-and-come-again” nature. Once the leaves reach a desirable size, you can harvest the outer leaves, allowing the inner ones to continue growing. This ensures a continuous supply throughout the winter.
Fava Beans
Fava beans or broad beans are not only a hearty vegetable but also a boon to the soil, as they help in fixing nitrogen. These beans offer a dual benefit: nutritious beans and improvement of soil health. Growing broad beans in containers during the winter can lead to a productive early spring harvest.
For winter cultivation, sow fava bean seeds in pots during early to mid-fall. This gives them a good start before the colder weather sets in and leads to an early spring harvest.
Fava beans show impressive resilience against light frosts, but for those colder snaps, consider offering added protection.
Aim for consistently moist soil. While they’re drought-tolerant to some degree, fava beans will thrive best when watered just before the soil dries out completely.
Plump, filled-out pods are a sign that they’re ready for harvest. While younger pods can be eaten pod and, mature ones are typically shelled to savor the beans inside.
Peppers
Growing peppers in pots during winter is a great way to keep your green thumb active. Choose dwarf or compact pepper varieties, as they are best suited for pot cultivation. A pot that’s at least 12 inches in diameter with good drainage is ideal, and either terra cotta, plastic, or ceramic will work well.
Use a well-draining potting mix and fertilize your pepper plants every two weeks with a balanced, water-soluble fertilizer. Peppers need plenty of sunlight, at least 6-8 hours a day, so place them in a sunny spot or use grow lights. Keep the temperature between 65°F and 75°F (18°C – 24°C) for optimal growth.
Water the plants to keep the soil consistently moist, avoiding overwatering to prevent root rot. Indoors, you’ll need to aid pollination by gently shaking the plants to distribute pollen. Keep an eye out for pests like aphids and spider mites, using organic insecticidal soaps or neem oil if necessary.
Harvest your peppers when they’re firm and have reached full color; regular harvesting encourages more fruit production. Home-grown peppers are a great addition to winter dishes, offering fresh flavor and a touch of summer warmth.
Tips for Winter Edible Gardening in Pots
Maximize Your Light Exposure: Winter days are shorter, so place your pots in areas that receive the most sunlight. If natural light is scarce, consider using grow lights to supplement.
Insulate Your Pots: Protect your plants from extreme cold. Wrap pots in bubble wrap or burlap, or place them against a warm wall to shelter them from frost.
Choose the Right Soil: Use high-quality potting mix that provides good drainage. This is crucial to prevent root rot in the colder, wetter months.
Monitor Watering Needs: Plants need less water in winter due to slower growth and evaporation rates. Check the soil moisture regularly and water only when necessary.
Utilize Vertical Space: If you’re limited in space, consider vertical gardening. Use trellises, hanging baskets, or stackable planters.
Protect from Frost: Be ready to cover your plants or move them indoors during frosty nights. Use cloches, frost blankets, or simply bring them inside.
Keep Pests at Bay: Indoor gardening can still attract pests. Check your plants regularly and use organic methods to control any infestations.
