How To Grow Kohlrabi
Soil Requirements for kohlrabi cultivation
Kohlrabi thrives in well-drained, loamy soil with a pH range of 6.0 to 7.5. Enriching the soil with organic matter, such as compost, helps improve its fertility and drainage. Ideal climate and temperature for growing kohlrabi
Kohlrabi prefers cool temperatures and is ideally grown in spring or fall. It thrives in regions with average temperatures between 50°F and 75°F (10°C and 24°C).

- Plant seeds or transplants in well-prepared soil, spacing them 6-8 inches apart.
- Water gently but consistently, ensuring the soil remains moist.
- Provide adequate sunlight (6-8 hours) for optimal growth.
Watering and fertilizing kohlrabi plants
Kohlrabi plants require regular watering, particularly during dry periods. Maintain consistent soil moisture but avoid overwatering, which can lead to root rot. Apply a balanced fertilizer once a month to promote healthy growth.
Common kohlrabi pests and diseases and their management
Kohlrabi may be susceptible to pests like cabbage worms, flea beetles, and aphids. Implementing organic pest control methods, such as handpicking or using neem oil, can help manage these issues.
Diseases like clubroot and powdery mildew can be prevented by crop rotation and ensuring good air circulation around plants.
Thinning and spacing kohlrabi plants
Thinning overcrowded kohlrabi seedlings promotes better growth. Maintain a spacing of 6-8 inches between plants to allow ample room for bulb development.
Mulching Kohlrabi
Apply a layer of organic mulch around kohlrabi plants to conserve moisture, suppress weeds, and regulate soil temperature.
Pruning and maintaining kohlrabi plants
Remove any yellow or damaged leaves regularly to encourage the growth of healthier leaves and bulbs. Inspect for signs of pests or diseases and take necessary action promptly.
