Growing Kohlrabi in Pots: A Complete Guide

Kohlrabi, that quirky bulbous vegetable, is surprisingly easy to grow, even in a pot! Here’s how I successfully grew mine, and how you can too.

I. Planning and Preparation

• Choose the right pot: Kohlrabi needs at least 12 inches of depth and a similar width. A larger pot is even better, allowing for more robust growth. I used a 15-inch diameter pot, and it worked perfectly. Make sure it has drainage holes to prevent root rot.
• Select your potting mix: Don’t use garden soil directly from your yard. Instead, opt for a high-quality potting mix that’s well-draining and rich in organic matter. I prefer a mix that contains peat moss, perlite, and compost. This ensures good aeration and nutrient retention.
• Source your seeds or seedlings: You can start from seeds or buy seedlings. Starting from seeds gives you more control, but seedlings offer a head start. I chose to start from seeds, as I enjoyed the process of nurturing them from the beginning.
• Choose the right location: Kohlrabi needs at least six hours of sunlight daily. Find a sunny spot on your patio, balcony, or even a sunny windowsill (if using a smaller pot). Protect your plants from strong winds.

II. Sowing Seeds (If Starting from Seed)

1. Prepare the potting mix: Fill your pot with the potting mix, leaving about an inch of space from the top. Gently water the mix until it’s evenly moist but not soggy.
2. Sow the seeds: Kohlrabi seeds are small. Plant them about ½ inch deep and 1-2 inches apart. I found that spacing them slightly further apart gave the plants more room to grow.
3. Cover and water: Lightly cover the seeds with more potting mix. Water gently again, using a watering can with a fine rose to avoid disturbing the seeds.
4. Maintain moisture: Keep the soil consistently moist but not waterlogged. Check the moisture level daily, especially during hot weather. Allow the top inch of soil to dry slightly between waterings.
5. Provide warmth: Kohlrabi seeds germinate best in temperatures between 65-75°F (18-24°C). If it’s cooler, consider using a heat mat to speed up germination.
6. Thinning: Once seedlings have two true leaves, thin them out, leaving the strongest plants about 6-8 inches apart. This gives each plant enough space to develop its bulb.

III. Transplanting Seedlings (If Starting from Seedlings)

1. Prepare the pot: Fill your pot with the potting mix, leaving about an inch of space from the top. Water thoroughly.
2. Dig holes: Make holes in the potting mix, large enough to accommodate the root balls of your seedlings. Space them 6-8 inches apart.
3. Carefully remove seedlings: Gently remove the seedlings from their containers, being careful not to damage the roots. If the roots are root-bound, gently loosen them.
4. Plant the seedlings: Place the seedlings in the holes, ensuring the top of the root ball is level with the surface of the potting mix. Fill in the holes with more potting mix, gently firming it around the base of each plant.
5. Water thoroughly: Water the newly planted seedlings thoroughly to settle the soil and help them establish themselves.

IV. Ongoing Care

1. Watering: Keep the soil consistently moist, but avoid overwatering. Water deeply and less frequently rather than shallowly and often. The frequency will depend on the weather and the size of your pot.
2. Fertilizing: Kohlrabi is a heavy feeder. Start fertilizing about 2-3 weeks after transplanting or when the seedlings have several true leaves. Use a balanced liquid fertilizer, diluted to half strength, every 2-3 weeks. Follow the instructions on the fertilizer packaging.
3. Weeding: Regularly remove any weeds that may compete with your kohlrabi for nutrients and water. This is especially important in smaller pots.
4. Pest and disease control: Monitor your plants regularly for pests and diseases. Common pests include aphids and flea beetles. Treat any infestations promptly using appropriate organic pest control methods.
5. Support (optional): For larger varieties of kohlrabi, you may need to provide some support to prevent the bulbs from touching the ground and rotting. You can use small stakes or a cage to support the plants.

V. Harvesting

1. Harvest time: Kohlrabi is ready for harvest when the bulbs are firm and about 2-3 inches in diameter. This usually takes 6-8 weeks from planting, depending on the variety and growing conditions. Don’t let the bulbs get too large, as they can become woody and tough.
2. Harvesting technique: Use a sharp knife to cut the bulbs off at the base of the stem. Be careful not to damage the surrounding plants.
3. Storage: Store harvested kohlrabi in the refrigerator for up to a week. You can also peel and chop it and freeze it for later use.

VI. Troubleshooting

• Yellowing leaves: This could indicate overwatering, underwatering, nutrient deficiency, or pest infestation. Check the soil moisture, adjust watering accordingly, and inspect for pests.
• Small bulbs: This could be due to overcrowding, insufficient sunlight, or nutrient deficiency. Ensure proper spacing, provide adequate sunlight, and fertilize regularly.
• Cracked bulbs: This often happens due to inconsistent watering. Aim for consistent moisture levels.

Frequently Asked Questions

What type of pot is best for kohlrabi pot gardening?

While any pot will work, larger pots (at least 12 inches in diameter and depth) are ideal for kohlrabi, which has a relatively large root system. Choose pots with drainage holes to prevent root rot. Terracotta pots are a good option because they allow for better air circulation, but plastic pots are also suitable.

What kind of soil is best for growing kohlrabi in pots?

Kohlrabi thrives in well-draining soil that is rich in organic matter. A good potting mix specifically designed for vegetables is a great starting point. You can also amend your soil with compost or other organic materials to improve its drainage and nutrient content. Avoid heavy clay soils, which can retain too much water and lead to root problems.

How often should I water my kohlrabi plants in pots?

Watering frequency depends on several factors, including the size of your pot, the type of soil, and the weather conditions. Generally, aim to keep the soil consistently moist but not soggy. Check the soil moisture regularly by sticking your finger a couple of inches into the soil. Water thoroughly when the top inch or two feels dry. During hot, dry weather, you may need to water more frequently.

How much sunlight do kohlrabi plants need?

Kohlrabi needs at least six hours of direct sunlight per day to thrive. Choose a location that receives ample sunlight, whether it’s a sunny spot on your balcony, patio, or even a south-facing windowsill. Insufficient sunlight can lead to poor growth and reduced yields.

When can I harvest my kohlrabi?

The harvest time for kohlrabi depends on the variety you’ve planted, but generally, you can harvest the bulbs when they reach about 2-3 inches in diameter. The bulbs should feel firm and solid. Harvesting too early will result in small, underdeveloped bulbs, while harvesting too late can lead to tough, woody bulbs.

What are some common problems encountered when growing kohlrabi in pots, and how can I solve them?

Some common issues include root rot (caused by overwatering), pest infestations (such as aphids or cabbage worms), and nutrient deficiencies. To prevent root rot, ensure good drainage and avoid overwatering. For pest control, consider using organic methods such as insecticidal soap or neem oil. Nutrient deficiencies can be addressed by using a balanced fertilizer specifically formulated for vegetables.

Can I grow kohlrabi in pots year-round?

Whether you can grow kohlrabi year-round depends on your climate. In warmer climates, you may be able to grow kohlrabi outdoors year-round. In colder climates, you’ll likely need to grow kohlrabi indoors during the winter months, using grow lights to supplement sunlight. Consider using a greenhouse or a cold frame to extend the growing season.

What are the benefits of growing kohlrabi in pots compared to growing it in the ground?

Growing kohlrabi in pots offers several advantages, including better control over the growing environment (soil, water, and nutrients), easier pest and disease management, and the ability to grow kohlrabi even in limited spaces. It’s also easier to move the pots to protect the plants from harsh weather conditions.
