Growing Kohlrabi: A Guide to Cultivating Delicious and Nutritious Brassicas
If you're looking for a new addition to your home garden, kohlrabi is a great choice. This unusual-looking vegetable, which is part of the brassica family, has a mild, sweet flavor and is packed with vitamins and minerals. Despite its exotic appearance, growing kohlrabi is actually quite easy - even for beginners. In this guide, we'll walk you through everything you need to know to successfully cultivate this tasty and nutritious plant.
What is Kohlrabi?
Kohlrabi (Brassica oleracea) is a member of the brassica family, which also includes popular vegetables like broccoli, cauliflower, and kale. The name "kohlrabi" comes from the German words for "cabbage turnip," which gives you an idea of what this vegetable looks like. Kohlrabi has a round, bulbous stem that sits just above the soil line, with leaves that grow from the top. The stem can be green, white, or purple, depending on the variety. Inside, it's crisp and white, with a texture similar to an apple or jicama.
Why Grow Kohlrabi?
There are plenty of reasons to add kohlrabi to your garden. For starters, it's a relatively low-maintenance vegetable that's easy to grow in most climates. Kohlrabi is also highly nutritious, packed with fiber, vitamin C, and other important nutrients. Additionally, kohlrabi is incredibly versatile in the kitchen. You can eat it raw or cooked, and it pairs well with a variety of flavors and cuisines.
How to Plant Kohlrabi
To get started with kohlrabi, you'll need to choose a planting location that gets at least six hours of sunlight per day. Kohlrabi prefers well-draining soil that's rich in organic matter, so consider amending your soil with compost or aged manure before planting.
You can plant kohlrabi seeds directly in the ground or start them indoors and transplant them later. If starting seeds indoors, sow them about four weeks before your last expected frost date. When planting outside, sow seeds ¼ to ½ inch deep, spacing them about six inches apart.
Keep the soil around your kohlrabi plants moist but not waterlogged. You may also want to mulch around the base of the plant to help retain moisture and suppress weeds.
Caring for Kohlrabi
Once your kohlrabi plants are established, they require relatively little care. However, there are a few things to keep in mind to ensure healthy growth and a good harvest.
First, make sure your plants have enough space to grow. Kohlrabi needs about six inches of space between plants, so thin them out if they get too crowded.
Second, keep an eye out for pests and diseases. Kohlrabi is susceptible to some of the same issues as other brassicas, including cabbage worms and clubroot. Inspect your plants regularly and take action if you notice any signs of trouble.
Finally, pay attention to the weather. Kohlrabi prefers cool and moist conditions, so make sure to water your plants during dry spells and provide shade during heat waves.
Harvesting and Using Kohlrabi
Depending on the variety, kohlrabi takes anywhere from 40 to 70 days to mature. Once the stem reaches two to three inches in diameter, it's ready to harvest. Use a sharp knife to cut the stem off at ground level.
Kohlrabi is delicious both raw and cooked. Try slicing it thinly and adding it to salads or slaws, or roast it with olive oil and herbs for a tasty side dish. You can also use kohlrabi greens in place of kale or collards in soups or sautés.
Whether you're a seasoned gardener or just starting out, growing kohlrabi is a fun and rewarding experience. With a little bit of planning and care, you can enjoy a bountiful harvest of this delicious and nutritious brassica. Happy planting!
