Caring for Kohlrabi Plants

Watering

Kohlrabi plants require regular watering to keep the soil consistently moist. The plants should be watered deeply, allowing the water to soak into the root zone. However, it is important to avoid over-watering, as this can lead to root rot. Watering should be done in the morning to allow any excess moisture to evaporate throughout the day.

Fertilizing

Kohlrabi plants benefit from a balanced fertilizer application before planting and throughout the growing season. A general purpose vegetable fertilizer with equal amounts of nitrogen, phosphorus, and potassium can be applied according to the manufacturer’s instructions. Fertilizer should be applied evenly around the plants, avoiding direct contact with the foliage to prevent burn.

Weeding

Regular weeding is important to keep the area around kohlrabi plants free from competition. Weeds can rob the plants of nutrients and water, reducing their overall health and productivity. Hand pulling weeds or using a hoe to remove them is an effective method of weed control. Applying a layer of mulch around the plants can also help suppress weed growth.

Pest Control

Kohlrabi plants may be susceptible to common garden pests such as aphids, cabbage worms, and flea beetles. Regularly inspect the plants for signs of pest damage, such as chewed leaves or discoloration. Insecticidal sprays or organic pest control methods can be used to manage infestations. Additionally, attracting beneficial insects like ladybugs and lacewings can help control pest populations.

Disease Prevention

Proper sanitation and disease prevention practices can help keep kohlrabi plants healthy. Avoid planting kohlrabi in areas where other brassica crops have been grown recently, as this can increase the risk of disease. Provide adequate spacing between plants to promote good air circulation, which can help prevent diseases like powdery mildew. Removing and destroying any diseased plant material can also help prevent the spread of diseases.

Harvesting

Kohlrabi plants are typically ready for harvest 55-65 days after planting. The bulbs should be harvested when they reach 2-3 inches in diameter. Using a sharp knife, cut the bulb from the stem at ground level. The leaves can also be harvested and used in cooking, similar to collard greens or kale. Harvesting the bulbs regularly will encourage new growth.

Storing

Kohlrabi bulbs can be stored in the refrigerator for up to 2 weeks. Remove the leaves from the bulbs and place them in a plastic bag or container with air holes. Store them in the vegetable crisper drawer to maintain freshness. The leaves can be stored separately in a plastic bag, but should be used within a few days.

Conclusion

Caring for kohlrabi plants involves providing adequate water, fertilization, and pest and disease control. With proper care, kohlrabi plants can produce a delicious and nutritious harvest of crunchy bulbs and flavorful leaves.

Harvesting and Storing Kohlrabi

Kohlrabi can be harvested when the bulb has reached a diameter of 2-3 inches. To harvest, use a sharp knife and cut the stem of the kohlrabi just above the soil level. Be careful not to damage the root system or neighboring plants.

Harvesting Tips

• Avoid letting the kohlrabi bulbs become too large as they may become woody and lose their flavor.
• Harvest kohlrabi promptly as they can become tough and fibrous if left in the ground for too long.
• Harvest the larger bulbs first, leaving the smaller ones to continue growing.
• Inspect harvested bulbs for any signs of damage or disease. Discard any damaged bulbs.

Storing Kohlrabi

Kohlrabi can be stored in a cool and moist environment to extend its shelf life. Here are some tips for storing kohlrabi:

• Remove any excess leaves attached to the bulb, leaving about an inch of stem.
• Place the bulbs in a plastic bag and store them in the refrigerator’s crisper drawer. Ensure that the bag is sealed tightly to retain moisture.
• Kohlrabi can be stored for up to two weeks in the refrigerator.
• For longer-term storage, kohlrabi can be blanched and frozen. Simply peel and slice the bulbs, blanch them in boiling water for 2-3 minutes, then plunge them into ice water to stop the cooking process. Drain and pack the blanched kohlrabi into freezer bags, removing as much air as possible before sealing. Frozen kohlrabi can be stored for up to six months.

By following these harvesting and storage tips, you can enjoy fresh and flavorful kohlrabi throughout the season!

Common Pests and Diseases of Kohlrabi

Kohlrabi, like any other vegetable, can be susceptible to pests and diseases. Being aware of these common problems can help gardeners identify and treat them early, ensuring a healthy and productive crop.

Pests

• Aphids: These small, soft-bodied insects can be found on the undersides of leaves and can cause stunted growth and distorted leaves. Regularly inspecting the plants and spraying them with a strong stream of water or applying an insecticidal soap can help control aphids.
• Cabbage Worms: These green caterpillars can chew holes in the leaves of kohlrabi plants. Handpicking them off the plants or using Bacillus thuringiensis (BT) can help control cabbage worms.
• Flea Beetles: These small, black beetles can chew small holes in the leaves and cause stunted growth. Protecting the plants with floating row covers or applying insecticides labeled for flea beetle control can help manage this pest.
• Slugs and Snails: These slimy creatures can chew holes in the leaves and damage the edible bulb of kohlrabi. Removing debris, mulching with sharp materials like crushed eggshells or diatomaceous earth, and handpicking can help control slugs and snails.

Diseases

• Clubroot: This soil-borne disease causes the roots of kohlrabi plants to become swollen and deformed. Rotating crops, improving soil drainage, and using resistant varieties can help prevent clubroot.
• Downy Mildew: A fungal disease that causes yellow or brown patches on the leaves and a fuzzy growth on the undersides. Ensuring adequate air circulation, avoiding overhead watering, and using fungicides can help manage downy mildew.
• Blackleg: This bacterial disease causes blackened stems near the soil line and stunted growth. Planting disease-free seedlings and practicing crop rotation can help prevent blackleg.
• Powdery Mildew: A fungal disease that forms a white, powdery coating on the leaves. Providing adequate spacing between plants, avoiding overhead watering, and using fungicides can help control powdery mildew.

By being vigilant and taking steps to prevent and manage these common pests and diseases, gardeners can ensure a successful harvest of kohlrabi.
