Growing Kohlrabi: An Indoor and Outdoor Guide

Kohlrabi is a fascinating and delicious member of the cabbage family, and growing it yourself, whether indoors or outdoors, is a rewarding experience. This guide will walk you through the process, from seed to harvest, covering both indoor and outdoor cultivation.

Section 1: Planning and Preparation

• Choose your growing method: Decide whether you’ll grow your kohlrabi indoors under grow lights or outdoors in your garden. Indoor growing offers more control over the environment but requires specific equipment. Outdoor growing is simpler but relies on natural conditions.
• Select your variety: Different kohlrabi varieties mature at different rates and have varying sizes and colors. Choose a variety suitable for your climate and growing season. Early maturing varieties are ideal for shorter seasons or indoor growing.
• Source your seeds: Purchase high-quality kohlrabi seeds from a reputable supplier. Look for descriptions of the variety’s characteristics, such as size, color, and days to maturity.
• Prepare your growing medium: For indoor growing, use a well-draining seed-starting mix. For outdoor growing, amend your soil with compost or other organic matter to improve drainage and fertility. Kohlrabi prefers slightly acidic soil (pH 6.0-6.8).
• Choose your containers (for indoor growing): Select containers at least 6 inches deep and wide to accommodate the kohlrabi’s root system. Ensure they have drainage holes to prevent waterlogging.

Section 2: Sowing the Seeds

Indoor Sowing

1. Fill your chosen containers with the seed-starting mix, leaving about half an inch of space from the top.
2. Moisten the soil thoroughly but avoid overwatering. The soil should be damp, not soggy.
3. Sow the seeds about ¼ inch deep and 1-2 inches apart. Gently cover the seeds with soil.
4. Water gently again using a spray bottle to avoid disturbing the seeds.
5. Cover the containers with clear plastic wrap or a humidity dome to maintain moisture and warmth. This helps with germination.
6. Place the containers under grow lights, ensuring they receive at least 12-16 hours of light per day. Maintain a temperature between 65-75°F (18-24°C).
7. Once the seeds germinate (usually within 5-10 days), remove the plastic wrap or humidity dome. Continue to provide adequate light and water.

Outdoor Sowing

1. Prepare the soil by removing weeds and rocks. Loosen the soil to a depth of about 12 inches.
2. Sow the seeds directly into the garden bed after the last frost. The soil temperature should be at least 50°F (10°C).
3. Plant the seeds about ¼ inch deep and 1-2 inches apart in rows spaced 12-18 inches apart.
4. Gently firm the soil around the seeds.
5. Water gently after sowing.
6. Keep the soil consistently moist until germination.

Section 3: Transplanting (for both indoor and outdoor)

1. Once the seedlings have developed 2-3 true leaves (not the seed leaves), they are ready for transplanting. This usually takes about 3-4 weeks.
2. For indoor seedlings: Carefully remove the seedlings from their containers, being mindful not to damage the roots. Transplant them into larger individual containers (at least 6 inches in diameter) filled with fresh potting mix.
3. For outdoor seedlings: Thin out the seedlings to one plant every 6-8 inches, leaving the strongest plants. Alternatively, you can carefully transplant the seedlings to their permanent location in the garden, maintaining the same spacing.
4. Water the transplanted seedlings thoroughly after transplanting.

Section 4: Ongoing Care

Watering

Kohlrabi needs consistent moisture, especially during dry periods. Water deeply and regularly, ensuring the soil remains moist but not waterlogged. Check the soil moisture regularly by sticking your finger a couple of inches into the soil. If it feels dry, it’s time to water.

Fertilizing

Feed your kohlrabi plants with a balanced fertilizer every 2-3 weeks. Use a liquid fertilizer diluted to half strength or a slow-release granular fertilizer according to package directions. Avoid over-fertilizing, as this can lead to poor bulb development.

Pest and Disease Control

Kohlrabi can be susceptible to pests such as aphids, cabbage worms, and flea beetles. Regularly inspect your plants for signs of pests and take appropriate action. Consider using insecticidal soap or neem oil for organic pest control. Good air circulation can help prevent fungal diseases.

Weeding

Keep the area around your kohlrabi plants free of weeds to prevent competition for nutrients and water. Regular weeding is essential for healthy growth.

Section 5: Harvesting

1. Kohlrabi is ready for harvest when the bulbs are firm and have reached the desired size, usually 2-3 inches in diameter. This typically takes 6-8 weeks after transplanting.
2. Harvest the bulbs by cutting them off at the base with a sharp knife. Be careful not to damage the surrounding leaves.
3. Store harvested kohlrabi in the refrigerator for up to a week.

Section 6: Troubleshooting

• Small bulbs: This can be due to overcrowding, insufficient nutrients, or inconsistent watering. Ensure proper spacing, fertilize regularly, and maintain consistent moisture.
• Bolting (premature flowering): This occurs when the plants are exposed to stress, such as extreme heat or drought. Choose a variety suitable for your climate and provide consistent watering and shade if necessary.
• Pest infestations: Regularly inspect your plants for pests and take appropriate action. Use organic pest control methods whenever possible.
• Disease problems: Ensure good air circulation and avoid overwatering to prevent fungal diseases. Remove and destroy any affected plants.

If you’re growing indoors, explore different grow lights and adjust the light cycle to optimize growth. For outdoor cultivation, pay close attention to soil conditions and amend as needed to ensure optimal drainage and nutrient levels. Don’t be afraid to get creative!
