10 Cold-Hardy Crops for Year-Round Harvest. Winter Vegetable Garden

When winter descends upon our gardens, it doesn't mean that we have to bid farewell to homegrown produce. With the right approach and a little ingenuity, you can enjoy a bountiful harvest even during the coldest months. In this comprehensive guide, we'll explore the top vegetables to grow in winter, along with essential tips and techniques to ensure a successful winter garden.

Before we delve into the specific vegetables ideal for winter, let's lay the groundwork for successful winter gardening. The key is to understand your climate and choose appropriate season extenders. These structures, such as cold frames, mini hoop tunnels, greenhouses, and polytunnels, create a protective environment for your crops.

When it comes to winter gardening, it's essential to select vegetables that can withstand the cold temperatures. The first step is understanding your region's climate and the specific challenges it poses. Climates vary, and what works in one area may not be suitable for another. Here's how you can get started:

1. Winter Vegetable Selection

Learning about winter gardening begins with the right choice of crops. If you're new to winter vegetable gardening, consider starting with a few cold-tolerant vegetables. In milder climates, a simple fabric row cover on PVC or metal hoops might suffice to protect your crops. For those in colder zones, more substantial protection in the form of cold frames or mini hoop houses is necessary.

2. Timing is Crucial

The growth of most vegetables slows down as daylight hours decrease. In areas where the day length falls below ten hours a day, which typically occurs in early November, it's crucial to ensure your winter vegetables have reached a harvestable size before this happens. Once they do, they can remain snug and protected in their season extenders, awaiting your harvest.

Now that you have a better understanding of the basics, let's delve into the top 8 vegetables that thrive in winter conditions:

1. Kale

No winter garden is complete without kale. As temperatures drop, the flavor of kale actually improves. Varieties like 'Winterbor' and 'Red Russian' are excellent choices. 'Winterbor' boasts deeply curled blue-green leaves, while 'Red Russian' features vivid purple stems and gray-green leaves, perfect for making kale chips.

2. Lettuce

Lettuce is a winter gardening superstar. Varieties like 'Winter Density,' 'Red Salad Bowl,' and 'Winter Marvel' are known for their cold-hardiness. Salanova® lettuce varieties have also been gaining popularity for their performance in unheated polytunnels.

3. Carrots

Winter carrots, often called "candy carrots," become exceptionally sweet after a few hard freezes. Varieties like 'Napoli,' 'Mokum,' or 'Bolero' are perfect for winter harvesting. Sow the seeds from late July through early August and provide insulation with mulch and row covers for an abundant supply.

4. Asian Greens

Asian greens like pac choi, tatsoi, mizuna, and mustard greens are fast-growing and perfect for winter structures like cold frames and polytunnels. Direct seed in early September or start the seedlings indoors before transplanting them to your garden beds.

5. Scallions

'Evergreen Hardy White' scallions are hardy and produce tender white stalks with long green tops. Direct sow the seed in September for a winter-long harvest with protection.

6. Mache

Also known as corn salad or lamb's lettuce, mache forms clusters of leaves that are harvested whole for salads. Varieties like 'Vit' are ideal for winter gardens and can self-sow easily.

7. Spinach

Spinach thrives in cool, shorter days and can be sown in cold frames and polytunnels. Varieties like 'Giant Winter,' 'Tyee,' 'Melody,' and 'Winter Bloomsdale' are excellent choices for winter harvesting.

8. Arugula

Arugula is a quick-growing green perfect for winter harvesting. Garden and wild varieties offer a range of flavors and textures. Seed arugula every few weeks starting in early September for a continuous supply of this peppery green.

9. Brussels Sprouts

Brussels sprouts are cold-hardy and thrive in winter weather. These mini cabbages are known for their sweet, nutty flavor. Plant them in late spring or early summer, and they'll be ready for harvest in winter. Be sure to provide support for the tall stalks.

10. Parsnips

Parsnips are a root vegetable that becomes sweeter after exposure to frost. They can be left in the ground throughout the winter and harvested as needed. Their unique sweet and earthy flavor makes them a delightful addition to winter meals.

One of the great things about winter vegetable gardening is that most vegetable gardens can accommodate these crops. Some, like Brussels sprouts, may take up more space and time, but the investment is well worth it. When selecting a spot for your winter vegetable garden, choose an open site with free-draining soil. Ensure that the soil is thoroughly cultivated before sowing or planting and enriched with organic material for the best results.

If you're short on ground space, containers can support a few plants. For those fortunate enough to have a greenhouse or polytunnel, you can use them to over-winter some crops and start others early. However, it's important to note that heating greenhouses for year-round harvests is rarely efficient.

It's crucial to understand that as the days grow shorter, most vegetables' growth slows down. In regions with less than ten hours of daylight, this typically occurs around early November. To ensure a bountiful harvest, your winter vegetables need to reach a harvestable size by that time. For colder zones, consider insulating structures like cold frames.

Mini hoop tunnels are one of the most effective tools for growing food in winter. To learn more about this technique, check out our online course "How to Build and Use Mini Hoop Tunnels in the Vegetable Garden."

When to seed or plant your winter crops depends on the specific crop. Most winter vegetables are either direct-seeded or transplanted from mid-summer to early autumn, with timing varying by the crop. Refer to our book, "The Year-Round Vegetable Gardener," for more details on timing winter crops.

Begin your winter gardening journey with the arrival of seed catalogs. Pay attention to the descriptions and opt for varieties with increased cold tolerance. For example, choose the hardiest kale varieties for your winter garden, such as 'Winterbor' and 'Redbor.'
