What is Kohlrabi?

Have you ever heard of kohlrabi? It's a member of the Brassica family, which includes other vegetables such as broccoli, cauliflower, and kale. Kohlrabi has a unique appearance with a globe-shaped stem that grows just above the ground, similar to cabbage. The plant also features large leaves that give it an overall bushy look.

Why should you grow Kohlrabi?

If you're in search of a low-maintenance vegetable to add to your garden, kohlrabi might just be the perfect option for you. Not only is it relatively easy to grow, but it's also packed with flavor and nutrition. Additionally, adding homegrown kohlrabi to your meals could save you money at the grocery store.

What are the benefits of growing your kohlrabi at home?

Growing your own kohlrabi allows you to have control over the growing process, ensuring that you're using organic methods and avoiding harmful chemicals. Plus, you'll have access to fresh, healthy produce right outside your door.

Kohlrabi Planting

Choosing the Soil

The soil that you plant your kohlrabi in can make all the difference in its growth and quality. Ideally, you want to use well-drained, fertile soil that has a neutral pH (around 7). If your soil is too acidic or alkaline, you can amend it with lime or sulfur, respectively. Be sure to avoid planting kohlrabi in compacted or rocky soil.

Planting Time

Kohlrabi is a cool-weather crop that grows best in spring or fall. Depending on your location, you can start planting kohlrabi as early as late winter or as late as mid-autumn. Try to avoid planting kohlrabi during the summer months when temperatures are too high for it to thrive.

Seed Germination

When planting kohlrabi from seed, it's important to keep the soil consistently moist until germination occurs. This typically takes around five to ten days, depending on soil temperature and moisture levels. Once the seeds have sprouted, thin them out so that each plant is about six inches apart.

Kohlrabi Care

Watering Kohlrabi

Maintaining proper moisture levels is essential to kohlrabi growth. The plant requires about one inch of water per week, but be sure not to overwater or underwater it. You'll know if your kohlrabi needs more water if its leaves start to wilt or yellow.

Fertilizing Kohlrabi

To promote strong growth and yield, you'll want to fertilize your kohlrabi with a balanced fertilizer that has equal amounts of nitrogen, phosphorus, and potassium. You can use a slow-release fertilizer applied at the base of the plant, or mix in some compost before planting.

Pest Management

Like many plants, kohlrabi is susceptible to certain pests. Common pests to look out for include cabbage worms, aphids, flea beetles, and root maggots. You can manage these pests naturally by using insecticidal soap or neem oil.

Disease Prevention

Diseases that commonly affect kohlrabi include clubroot, blackleg, and powdery mildew. To prevent these diseases, be sure to rotate your crops and keep the area around your plants clean and free of debris.

Harvesting Kohlrabi

How to Tell When Kohlrabi is Ready for Harvest

Kohlrabi typically takes about 55 days from planting until maturity. You'll know it's ready for harvest when the stem reaches around two to three inches in diameter. To test if it's ready, gently dig around the base of the plant and inspect the bulb.

Steps to Properly Harvest Kohlrabi

When harvesting kohlrabi, use a sharp knife or pruning shears to cut the stem just above ground level. Be sure not to damage any nearby roots or stems. Once you've harvested your kohlrabi, store it in the fridge or use it right away.

Final Thoughts on Growing Kohlrabi
