Kohlrabi, also known as German turnip, is a versatile and nutritious vegetable that can be a great addition to your garden. Growing and harvesting it successfully requires some specific tips to ensure a bountiful harvest of fresh, crunchy kohlrabi.
Choosing the Right Variety and Planting Time
Select a kohlrabi variety suited to your climate and growing season. There are both purple and green varieties, each with slightly different flavors. Plant kohlrabi in early spring or late summer, avoiding the hottest months, as extreme heat can cause the plants to bolt or become woody.
Preparing the Soil
Kohlrabi prefers loose, well-draining soil rich in organic matter. Before planting, work compost or aged manure into the soil to provide nutrients. Maintain a soil pH between 6.0 and 7.5 for optimal growth.
Planting Tips
- Space seeds or seedlings about 4 inches apart in rows 12 inches apart.
- Plant seeds ½ inch deep or transplant seedlings when they are 3-4 inches tall.
- Water thoroughly after planting to settle the soil.
Caring for Your Kohlrabi
Consistent watering is key to producing tender, flavorful kohlrabi. Keep the soil evenly moist, but not waterlogged. Mulching around the plants helps retain moisture and suppress weeds. Fertilize with a balanced fertilizer every few weeks to promote healthy growth.
Harvesting Kohlrabi
Kohlrabi is ready to harvest when the bulbs reach about 2 to 3 inches in diameter, usually 45 to 60 days after planting. Use a sharp knife or garden shears to cut the bulb at the base, leaving some stem attached. For the best flavor and texture, harvest before the bulb becomes woody or overly large.
Tips for a Successful Harvest
- Check the size regularly to avoid overgrowth.
- Store harvested kohlrabi in the refrigerator for up to a week.
- Use the greens in salads or sauté them for added flavor.
With proper care and timing, growing and harvesting fresh kohlrabi can be a rewarding experience. Enjoy its crisp texture and mild flavor in a variety of dishes, straight from your garden!
