Growing Kohlrabi in Pots: A Beginner’s Guide
Hey there, fellow gardening enthusiasts! Ever thought about growing kohlrabi but felt limited by space? Well, I’m here to tell you that you absolutely can cultivate this quirky and delicious vegetable in pots! It’s easier than you might think, and I’m going to walk you through every step of the process. Get ready to enjoy fresh, homegrown kohlrabi, even if you only have a balcony or small patio.
Choosing the Right Variety and Pot
Before we get our hands dirty, let’s talk about the essentials. Not all kohlrabi varieties are created equal when it comes to container gardening. And the pot itself plays a crucial role in your success.
* Variety Selection: Opt for smaller, faster-maturing varieties. ‘Early White Vienna’ and ‘Early Purple Vienna’ are excellent choices. They tend to be more compact and reach maturity quicker, making them perfect for pots. Avoid larger, slower-growing varieties that need more space.
* Pot Size: Kohlrabi needs room for its roots to develop. A pot that’s at least 12 inches in diameter and 12 inches deep is ideal for a single plant. If you’re planning to grow multiple kohlrabi plants in one container, choose a larger pot accordingly. Remember, crowded plants won’t thrive.
* Drainage: This is non-negotiable! Your pot *must* have drainage holes. Kohlrabi hates sitting in soggy soil, which can lead to root rot. If your pot doesn’t have drainage holes, you’ll need to drill some.
* Material: The material of the pot is less critical, but consider terracotta or plastic. Terracotta pots are porous, which helps with drainage and aeration, but they can dry out faster. Plastic pots retain moisture better, but you need to be extra careful not to overwater.
Preparing the Soil
Kohlrabi needs nutrient-rich, well-draining soil to flourish. Don’t just grab any old dirt from your backyard!
* The Perfect Mix: I recommend using a high-quality potting mix specifically formulated for vegetables. You can also create your own mix by combining equal parts of:
* Compost: Provides essential nutrients and improves soil structure.
* Peat moss or coco coir: Helps retain moisture.
* Perlite or vermiculite: Improves drainage and aeration.
* Adding Nutrients: Kohlrabi are heavy feeders, so it’s a good idea to amend your soil with a slow-release fertilizer. Look for a balanced fertilizer with an NPK ratio (nitrogen, phosphorus, potassium) of around 10-10-10 or 14-14-14. Follow the instructions on the fertilizer package for application rates.
* pH Level: Kohlrabi prefers a slightly acidic to neutral soil pH of around 6.0 to 7.0. You can test your soil pH with a soil testing kit, which you can find at most garden centers. If your soil is too alkaline, you can amend it with sulfur. If it’s too acidic, you can add lime.
Planting Your Kohlrabi
Now for the fun part! Let’s get those kohlrabi seeds or seedlings into their new home.
* Starting from Seed: You can start kohlrabi seeds indoors 4-6 weeks before the last expected frost. Sow the seeds about 1/4 inch deep in seed-starting trays or small pots filled with seed-starting mix. Keep the soil moist and warm (around 70-75°F). Once the seedlings have a few true leaves, you can transplant them into your larger pots.
* Transplanting Seedlings: If you’re using seedlings from a nursery, gently remove them from their containers and loosen the roots slightly. Dig a hole in the center of your pot that’s large enough to accommodate the root ball. Place the seedling in the hole, making sure the top of the root ball is level with the soil surface. Fill in the hole with soil and gently firm it around the base of the plant.
* Spacing: If you’re planting multiple kohlrabi plants in one pot, space them at least 6-8 inches apart. This will give them enough room to grow without crowding each other.
* Watering: After planting, water the kohlrabi thoroughly. The soil should be moist but not soggy.
Caring for Your Kohlrabi
Once your kohlrabi is planted, it’s time to provide the care it needs to thrive.
* Sunlight: Kohlrabi needs at least 6 hours of sunlight per day. Place your pots in a sunny location where they’ll receive plenty of direct sunlight. If you don’t have a sunny spot, you can supplement with grow lights.
* Watering: Water your kohlrabi regularly, especially during hot, dry weather. The soil should be consistently moist but not waterlogged. Check the soil moisture by sticking your finger about an inch into the soil. If it feels dry, it’s time to water.
* Fertilizing: Kohlrabi are heavy feeders, so you’ll need to fertilize them regularly. Use a liquid fertilizer diluted to half strength every 2-3 weeks. Look for a balanced fertilizer or one that’s slightly higher in phosphorus and potassium.
* Weeding: Keep your pots free of weeds. Weeds compete with kohlrabi for nutrients and water. Hand-pull any weeds that appear.
* Pest Control: Kohlrabi can be susceptible to pests like aphids, cabbage worms, and flea beetles. Inspect your plants regularly for signs of pests. If you find any, you can treat them with insecticidal soap or neem oil. These are both organic options that are safe for use on edible plants.
* Bolting: Bolting is when a plant prematurely flowers and goes to seed. This can happen if kohlrabi is exposed to extreme temperatures or stress. To prevent bolting, keep the soil consistently moist, provide adequate shade during hot weather, and harvest your kohlrabi when it’s the right size.
Harvesting Your Kohlrabi
The moment you’ve been waiting for! Harvesting your homegrown kohlrabi.
* Timing: Kohlrabi is typically ready to harvest 6-8 weeks after planting. The bulb should be about 2-3 inches in diameter. Don’t let it get too large, as it can become tough and woody.
* How to Harvest: To harvest kohlrabi, simply cut the bulb from the stem with a sharp knife. Leave about an inch of stem attached to the bulb.
* Storage: Kohlrabi can be stored in the refrigerator for several weeks. Remove the leaves before storing, as they can draw moisture from the bulb.
Troubleshooting Common Problems
Even with the best care, you might encounter some problems while growing kohlrabi. Here are a few common issues and how to address them:
* Yellowing Leaves: This can be caused by overwatering, underwatering, nutrient deficiencies, or pests. Check the soil moisture and adjust your watering accordingly. Fertilize your plants regularly. Inspect them for pests and treat them as needed.
* Splitting Bulbs: This is usually caused by inconsistent watering. Keep the soil consistently moist, especially during dry spells.
* Tough or Woody Bulbs: This can happen if you let the kohlrabi get too large before harvesting. Harvest them when they’re 2-3 inches in diameter.
* Lack of Bulb Formation: This can be caused by insufficient sunlight, poor soil, or overcrowding. Make sure your plants are getting at least 6 hours of sunlight per day. Use a high-quality potting mix and fertilize them regularly. Space your plants adequately.
