 How To Grow Kohlrabi?

Kohlrabi is an easy-to-grow vegetable that thrives in cool seasons. It has a mild, sweet flavor similar to cabbage and broccoli stems.

Growing kohlrabi home ensures fresh, crisp salads, stir-fries, and roasting harvests. This guide covers everything from planting to harvesting, providing essential details for beginners and experienced gardeners alike.

Best Growing Conditions

Kohlrabi grows best in cool temperatures between 45-75°F, making it an excellent choice for both spring and fall gardening. It requires well-draining, fertile soil with a pH of 6.0-7.5 to ensure proper nutrient absorption.

If your soil is too acidic, adding lime can help balance the pH, while compost and organic matter enhance fertility. Full sun exposure of at least six hours per day is ideal for healthy growth, though partial shade can be tolerated in hotter climates.

Proper spacing is essential, so plant kohlrabi 6-8 inches apart to allow room for bulbs to develop without crowding, which can lead to stunted growth.

How To Plant Kohlrabi

• When to Plant:

1. Spring: Plant seeds 3-4 weeks before the last frost. This allows the seedlings to be established before the temperature rises.

2. Fall: Sow seeds 8-10 weeks before the first frost. This ensures a harvest before the winter freeze.

• Starting from Seeds:

1. Direct sow in the garden or start indoors 4-6 weeks before transplanting. If starting indoors, use seed trays with a high-quality potting mix to promote strong seedling growth.

2. Sow seeds ¼ inch deep and 2 inches apart. Once seedlings emerge, thin them to maintain proper spacing.

• Transplanting:

Once seedlings sprout and grow to a few inches tall, thin them to ensure proper spacing. Transplant carefully to avoid disturbing the roots, as this can slow down their development.

Caring For Kohlrabi Plants

• Watering: Keep the soil consistently moist but not soggy. Water regularly, especially during dry periods, to prevent cracking or splitting of the bulbs. Using a drip irrigation system or soaker hose can help maintain even moisture levels.
• Fertilizing: Use a balanced fertilizer (10-10-10) every few weeks to encourage healthy growth. Organic options like compost tea or fish emulsion can also be beneficial. Avoid excessive nitrogen, as this can lead to lush foliage but small bulbs.
• Mulching: Helps retain moisture and suppress weeds. Apply a layer of mulch around the plants to keep the soil cool and reduce competition from weeds.
• Pest & Disease Control:
  • Watch for cabbage worms, aphids, and flea beetles. These pests can damage leaves and hinder growth.
  • Use row covers or neem oil as organic solutions to keep pests at bay. Introducing beneficial insects like ladybugs can also help control pest populations naturally.

Harvesting Kohlrabi

• When to Harvest:
  • Kohlrabi is ready in 45-60 days when bulbs reach 2-3 inches wide. Harvesting at the right size ensures a tender, sweet flavor. Larger bulbs can become woody and tough, making them less palatable.
• How to Harvest:
  • Cut the stem just above the soil level. Use a sharp knife or garden shears to avoid damaging the plant.
  • The leaves are edible and can be used like kale or spinach. Harvest them while young for the best texture and flavor.

How To Use Kohlrabi

• Raw: Sliced in salads or slaws. Kohlrabi adds a crisp, refreshing crunch when eaten raw. Try shredding it with carrots and apples for a delicious slaw.
• Cooked: Roasted, stir-fried, or added to soups. Roasting brings out its natural sweetness, while stir-frying pairs well with garlic and ginger.
• Pickled: A crunchy, tangy snack. Pickling is a great way to preserve kohlrabi and enhance its flavor with vinegar and spices.

Common Problems & Solutions

• Bolting: Prevent by keeping plants cool in hot weather. Once kohlrabi bolts (sends up a flowering stalk), the bulb stops growing and becomes tough. Providing shade or mulching can help regulate soil temperature.
• Small Bulbs: Ensure proper spacing and fertilizing. Overcrowding leads to small, underdeveloped bulbs. Make sure to thin seedlings and provide adequate nutrients.
• Pests: Use floating row covers or companion planting. Planting kohlrabi near aromatic herbs like rosemary or thyme can help repel pests naturally.
