How to Grow Kohlrabi in a Backyard Farm System

by

Growing kohlrabi in your backyard can be a rewarding experience, providing you with a nutritious and versatile vegetable. With the right techniques, even beginner gardeners can successfully cultivate this cool-season crop.

Understanding Kohlrabi

Kohlrabi, also known as German turnip, is a member of the cabbage family. It features a bulbous stem that can be green, purple, or white, with leafy greens on top. Its mild flavor makes it suitable for salads, stir-fries, and even roasting.

Preparing Your Garden

Choose a sunny location in your backyard that receives at least 6 hours of direct sunlight daily. Ensure the soil is well-draining and rich in organic matter. You can improve soil fertility by mixing in compost or aged manure before planting.

Planting Kohlrabi

Sow seeds directly into the soil about ½ inch deep, spacing them 4-6 inches apart. Thin seedlings to 8-10 inches apart once they are a few inches tall. You can also start seeds indoors 4-6 weeks before the last frost date for an earlier harvest.

Caring for Your Kohlrabi

Regular watering is essential, especially during dry spells. Keep the soil consistently moist but not waterlogged. Mulching around the plants helps retain moisture and suppress weeds.

Fertilizing Tips

Apply a balanced fertilizer once the plants are established. Use a nitrogen-rich fertilizer to promote leafy growth and a potassium-rich one as the bulbs develop. Follow the instructions on the fertilizer package for best results.

Harvesting Kohlrabi

Kohlrabi is ready to harvest when the bulbs reach about 2-3 inches in diameter. Use a sharp knife to cut the bulb at the base, leaving some of the stem attached. The greens can be harvested and used in salads or cooked dishes.

Tips for Success

  • Plant in early spring or late summer for best growth.
  • Keep the soil evenly moist to prevent woody textures.
  • Thin seedlings to avoid overcrowding.
  • Monitor for pests like aphids and cabbage worms.

With proper care and attention, you can enjoy fresh, homegrown kohlrabi throughout the growing season. Happy gardening!
