Growing Kohlrabi in Your Own Garden: Here’s How!

I love kohlrabi! That crunchy, slightly sweet taste is simply unbeatable, and the best part is that it’s super easy to grow in your own garden. I’ll show you how to bring in a bountiful kohlrabi harvest with a few simple steps and a little patience.

What You Need for Kohlrabi Cultivation:

Kohlrabi seeds (it’s best to choose a variety suitable for your region)
Seed starting mix (or coconut coir pellets)
Seed starting pots or trays
Garden soil (preferably enriched with compost)
Garden tools (spade, rake, trowel)
Watering can or garden hose
Possibly: Slug protection (slug pellets or a slug fence)
Possibly: Fleece or netting to protect against cabbage white butterflies

The Preparation: The Foundation for a Successful Harvest

Before we start with the actual cultivation, good preparation is the be-all and end-all. This starts with choosing the right location.

The location: Kohlrabi loves the sun! Choose a sunny spot in your garden where the kohlrabi gets at least six hours of sun per day. Partial shade is also possible, but the harvest might be slightly smaller.
The soil: The soil should be loose, rich in humus, and well-draining. Kohlrabi does not like waterlogging. I recommend enriching the soil with compost before planting. This ensures a good supply of nutrients and improves the soil structure.
Crop rotation: Kohlrabi belongs to the cruciferous family. Therefore, you should not plant it after other cruciferous plants (e.g., cabbage, radishes, horseradish) to avoid diseases and pests. A good preceding crop are legumes (e.g., peas, beans), as they enrich the soil with nitrogen.

Starting Seeds: Small Plants, Big Success

I always start my kohlrabi plants myself. This has the advantage that I can determine the plant’s strength myself and they are optimally prepared for transplanting.

Sowing: Fill the seed starting pots or trays with seed starting mix. Press the soil down lightly and sow the kohlrabi seeds about 1 cm deep. Cover the seeds with soil and water them gently.
Location: Place the seed starting pots in a bright and warm place. A temperature of 18-20 degrees Celsius is ideal.
Moisture: Keep the soil evenly moist, but not too wet. Avoid waterlogging, as the seeds can otherwise rot.
Germination: Germination usually takes 5-10 days. As soon as the first seedlings are visible, you can lower the temperature slightly (to about 15-18 degrees Celsius).
Pricking out: When the seedlings have developed their first true leaves (after the cotyledons), it’s time to prick them out. This means you carefully take the small plants out of the seed starting pots and transplant them into larger pots. Be careful not to damage the roots.

Planting Out: Off to the Garden Bed!

Once the kohlrabi plants are strong enough (about 10-15 cm high) and there is no more danger of frost (usually from mid-May), they can be planted out in the garden bed.

Preparing the bed: Loosen the soil in the bed thoroughly and remove weeds. Work in compost or organic fertilizer to enrich the soil with nutrients.
Planting distance: The planting distance should be about 25-30 cm between plants and 30-40 cm between rows. This gives the kohlrabi bulbs enough space to grow.
Planting: Use a trowel to make small holes in the bed. Carefully place the kohlrabi plants in the holes and fill them with soil. Press the soil down lightly and water the plants thoroughly.
Protection: To protect the young plants from slugs and cabbage whites, you can sprinkle slug pellets or stretch a fleece or net over the bed.

The Care: So the Kohlrabi Thrives Magnificently

After planting out, it is important to care for the kohlrabi regularly so that it can grow and thrive optimally.

Watering: Kohlrabi needs regular water, especially in dry periods. Make sure the soil is always slightly moist, but avoid waterlogging.
Fertilizing: Fertilize the kohlrabi regularly with organic fertilizer or compost. This ensures a good supply of nutrients and promotes the growth of the bulbs.
Weeding: Keep the bed clean of weeds. Weeds deprive the kohlrabi of nutrients and water.
Pests and diseases: Watch out for pests like slugs, cabbage whites, and flea beetles. Combat them with suitable means if necessary. Kohlrabi can also be affected by diseases like clubroot. Ensure good crop rotation and use resistant varieties.

The Harvest: The Reward for Your Efforts

Depending on the variety and weather, the kohlrabi is ready for harvest about 8-12 weeks after sowing.

Harvest time: The ideal harvest time is when the bulbs have a diameter of about 8-10 cm. Then they are particularly tender and juicy.
Harvesting: Carefully pull the kohlrabi out of the ground or cut it off with a knife. Remove the leaves and roots.
Storage: Kohlrabi can be stored in the refrigerator for about a week. It is best to wrap it in a damp cloth. You can also freeze kohlrabi. For this, you should peel it beforehand and cut it into pieces.

Additional Tips for a Bountiful Harvest

Early varieties: If you want to harvest kohlrabi early in the year, you can choose early varieties and start them in a greenhouse or cold frame.
Succession planting: To ensure a continuous harvest, you can re-sow kohlrabi every few weeks.
Companion planting: Kohlrabi gets along well with other vegetables like lettuce, radishes, spinach, and dill.
Soil improvement: If your soil is very sandy or clayey, you can improve it with compost, humus, or bentonite.

Common Problems and Solutions

Clubroot: This disease affects the roots and leads to growths. As a preventive measure, you should maintain good crop rotation and use resistant varieties.
Slugs: Slugs can eat the young plants bare. Protect your plants with slug pellets or a slug fence.
Cabbage whites: The caterpillars of the cabbage white butterfly eat the leaves of the kohlrabi. Protect your plants with a fleece or net.
Flea beetles: Flea beetles are small beetles that eat holes in the leaves. Keep the soil moist and combat the flea beetles with insecticides if necessary.

Kohlrabi Varieties: A Small Selection

There are many different kohlrabi varieties that differ in color, size, and taste. Here is a small selection:

‘Blue Delicacy’: A blue variety with a slightly sweet taste.

‘Delikatess White’: A classic, white variety with a mild taste.

Frequently Asked Questions (FAQ)

What is the best time of year to plant kohlrabi?

Kohlrabi is a cool-season crop, meaning it thrives in cooler temperatures. The best time to plant kohlrabi depends on your climate. In areas with mild winters, you can plant kohlrabi in the fall for a winter harvest. In colder climates, plant kohlrabi in the early spring, about 4-6 weeks before the last expected frost. You can also start seeds indoors 6-8 weeks before the last frost and transplant them outdoors once the soil has warmed up. For a continuous harvest, consider succession planting, sowing seeds every 2-3 weeks. This will ensure a steady supply of fresh kohlrabi throughout the growing season.

How much sunlight does kohlrabi need?

Kohlrabi requires at least 6 hours of direct sunlight per day to thrive. Choose a planting location that receives ample sunlight throughout the day. If you live in a particularly hot climate, providing some afternoon shade can help prevent the kohlrabi bulbs from becoming tough and bitter. Insufficient sunlight can lead to leggy growth and smaller, less flavorful bulbs.

What kind of soil is best for growing kohlrabi?

Kohlrabi prefers well-drained, fertile soil that is rich in organic matter. The ideal soil pH is between 6.0 and 7.5. Before planting, amend the soil with compost or well-rotted manure to improve drainage and fertility. Avoid planting kohlrabi in heavy clay soil, as this can lead to waterlogging and root rot. If you have clay soil, consider adding sand or other amendments to improve drainage. A soil test can help you determine the pH and nutrient levels of your soil, allowing you to make necessary adjustments before planting.

How often should I water kohlrabi?

Kohlrabi needs consistent moisture to grow properly. Water deeply and regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged. Mulching around the plants can help retain moisture and suppress weeds. Overwatering can lead to root rot, while underwatering can cause the bulbs to become tough and woody. Check the soil moisture regularly and adjust your watering schedule accordingly.

What are some common pests and diseases that affect kohlrabi?

Kohlrabi can be susceptible to several pests and diseases, including aphids, cabbage worms, flea beetles, and clubroot. To prevent pest infestations, consider using row covers or introducing beneficial insects like ladybugs. Regularly inspect your plants for signs of pests and diseases, and take action promptly. Clubroot is a soilborne disease that can cause swollen and distorted roots. To prevent clubroot, practice crop rotation and avoid planting kohlrabi in the same location year after year. Choose disease-resistant varieties whenever possible.

How do I know when kohlrabi is ready to harvest?

Kohlrabi is typically ready to harvest when the bulbs are about 2-3 inches in diameter. The exact size will depend on the variety. The bulbs should be firm and smooth. Avoid letting the bulbs grow too large, as they can become tough and woody. To harvest, simply cut the bulb from the stem just above the soil line. The leaves are also edible and can be cooked like spinach or kale.

Can I grow kohlrabi in containers?

Yes, kohlrabi can be successfully grown in containers. Choose a container that is at least 12 inches deep and wide to allow the roots to develop properly. Use a high-quality potting mix that is well-draining. Be sure to provide adequate sunlight and water. Container-grown kohlrabi may require more frequent watering and fertilization than kohlrabi grown in the ground.

How do I store kohlrabi after harvesting?

After harvesting, remove the leaves and store the kohlrabi bulbs in the refrigerator. They can be stored for several weeks if kept properly. The leaves can also be stored in the refrigerator, but they will not last as long as the bulbs. To extend the shelf life of the bulbs, wrap them in a damp paper towel and store them in a plastic bag.

What are some ways to use kohlrabi in cooking?

Kohlrabi is a versatile vegetable that can be used in a variety of dishes. It can be eaten raw, cooked, pickled, or fermented. Raw kohlrabi can be grated into salads or used as a crudité with dips. Cooked kohlrabi can be steamed, roasted, sautéed, or added to soups and stews. The leaves can be cooked like spinach or kale. Kohlrabi can also be pickled or fermented to create a tangy and flavorful condiment.

Is kohlrabi a healthy vegetable?

Yes, kohlrabi is a very healthy vegetable. It is low in calories and high in fiber, vitamins, and minerals. Kohlrabi is a good source of vitamin C, potassium, and vitamin B6. It also contains antioxidants that can help protect against cell damage. Adding kohlrabi to your diet can help improve your overall health and well-being.
