What is Kohlrabi?
Kohlrabi, also known as German turnip, is a member of the cabbage family. It has a bulbous stem that can be green, purple, or white, and is known for its mild, sweet flavor. Both the bulb and the leaves are edible and rich in vitamins and minerals.

- White Vienna
- Fast growing varieties for quick harvest
Planting Kohlrabi
Start seeds indoors 4-6 weeks before the last frost date or sow directly into the garden once the soil warms up. Space plants about 4 inches apart in rows that are 12-18 inches apart. Ensure the soil is well-drained and rich in organic matter.
Soil Preparation
Prepare your soil by mixing in compost or aged manure. Kohlrabi prefers a pH between 6.0 and 7.5. Proper soil preparation helps promote healthy growth and tender bulbs.
Caring for Your Kohlrabi
Regular watering is essential, especially during dry spells. Keep the soil consistently moist but not waterlogged. Mulching around the plants can help retain moisture and suppress weeds.
Fertilizing
Apply a balanced fertilizer every few weeks to support healthy growth. Avoid excessive nitrogen, which can lead to lush leaves but poor bulb development.
Harvesting Kohlrabi
Most kohlrabi varieties are ready to harvest 50-60 days after planting. The bulbs should be about 2-4 inches in diameter. Use a sharp knife to cut the bulbs at soil level. Harvest promptly to prevent the bulbs from becoming woody or cracking.
Tips for Success
- Thin seedlings to prevent overcrowding
- Keep the soil evenly moist
- Protect plants from pests like aphids and cabbage worms
- Use row covers for extra protection
With proper care and attention, growing kohlrabi can be a delightful addition to your vegetable garden. Enjoy harvesting and eating this nutritious vegetable fresh from your garden!
