Growing kohlrabi can be a rewarding experience for both beginner and experienced gardeners. This guide provides step-by-step instructions to help you cultivate healthy and delicious kohlrabi plants in your garden.
Choosing the Right Location and Soil Preparation
Select a sunny spot in your garden that receives at least 6 hours of direct sunlight daily. Kohlrabi prefers well-drained, fertile soil with a pH between 6.0 and 7.5. Before planting, enrich the soil with compost or organic matter to improve fertility and drainage.
Planting Kohlrabi Seeds
Start by sowing kohlrabi seeds indoors 4-6 weeks before the last expected frost date or directly in the garden once the soil temperature reaches at least 45°F (7°C). Sow seeds ½ inch deep and space them about 2 inches apart. Thin seedlings later to 4-6 inches apart to give each plant room to grow.
Watering and Care
Keep the soil consistently moist but not waterlogged. Water deeply once or twice a week, especially during dry spells. Mulching around the plants helps retain moisture and suppress weeds. Fertilize with a balanced fertilizer every few weeks to promote healthy growth.
Thinning and Harvesting
When seedlings are about 2 inches tall, thin them to 4-6 inches apart to prevent overcrowding. Kohlrabi is ready to harvest approximately 50-60 days after planting when the bulbs reach about 3-4 inches in diameter. Use a sharp knife to cut the bulbs at soil level.
Tips for Successful Cultivation
- Plant in succession every 2-3 weeks for a continuous harvest.
- Protect plants from pests like aphids and cabbage worms.
- Maintain consistent watering and fertilization.
- Rotate crops annually to prevent soil-borne diseases.
