Growing Kohlrabi in Small Spaces: A Beginner’s Guide
Hey there, fellow gardening enthusiasts! So, you’re itching to grow some kohlrabi but think you don’t have the space? Think again! I’m here to tell you that you absolutely can cultivate this quirky and delicious vegetable, even if you’re working with a tiny balcony, patio, or just a small corner of your yard. Kohlrabi is surprisingly well-suited for container gardening, and I’m going to walk you through everything you need to know to get started.
What is Kohlrabi Anyway?
Before we dive in, let’s quickly cover what kohlrabi actually is. Often called a “German turnip,” kohlrabi isn’t a root vegetable like a turnip. It’s actually a member of the cabbage family, and the part we eat is the swollen stem that grows above ground. It tastes like a cross between a turnip and a cabbage, with a slightly sweet and mild flavor. You can eat it raw, cooked, or even pickled!
Why Grow Kohlrabi in Containers?
There are several reasons why growing kohlrabi in containers is a fantastic idea:
* Space-Saving: Obviously, containers allow you to grow kohlrabi even if you have limited space.
* Control: You have complete control over the soil quality, watering, and sunlight exposure.
* Mobility: You can easily move your containers to follow the sun or protect them from harsh weather.
* Pest Control: Containers can help reduce the risk of soilborne pests and diseases.
* Early Harvest: Container-grown kohlrabi often matures faster than those grown in the ground.
Choosing the Right Variety
Not all kohlrabi varieties are created equal when it comes to container gardening. Look for varieties that are known for their compact size and early maturity. Here are a few of my favorites:
* ‘Early White Vienna’: A classic, reliable variety that produces pale green bulbs.
* ‘Early Purple Vienna’: Similar to ‘Early White Vienna’ but with a beautiful purple hue.
* ‘Kossak’: A giant variety that can get quite large, but still performs well in larger containers.
* ‘Kolibri’: A vibrant purple variety that is known for its excellent flavor and disease resistance.
* ‘Superschmelz’: Another giant variety, but it stays tender even when it gets quite large.
Materials You’ll Need
Alright, let’s gather our supplies! Here’s what you’ll need to get your kohlrabi container garden up and running:
* Containers: Choose containers that are at least 12 inches in diameter and 12 inches deep. This will give the kohlrabi roots plenty of room to grow. Make sure the containers have drainage holes!
* Potting Mix: Use a high-quality potting mix that is well-draining and rich in organic matter. Avoid using garden soil, as it can compact in containers and hinder drainage.
* Kohlrabi Seeds or Seedlings: You can start kohlrabi from seed or purchase seedlings from a local nursery.
* Watering Can or Hose: For watering your plants.
* Fertilizer: A balanced, water-soluble fertilizer or slow-release fertilizer.
* Trowel or Small Shovel: For planting.
* Optional: Mulch (such as straw or wood chips) to help retain moisture and suppress weeds.
Step-by-Step Planting Guide
Okay, let’s get our hands dirty! Here’s how to plant your kohlrabi in containers:
1. Prepare the Containers: Fill your containers with potting mix, leaving about an inch or two of space at the top. Gently pat down the soil.
2. Sowing Seeds (if starting from seed): Sow seeds about ½ inch deep and 1 inch apart. You can sow multiple seeds per container and then thin them out later to the strongest seedling.
3. Transplanting Seedlings (if using seedlings): Gently remove the seedlings from their nursery pots. Loosen the roots slightly. Dig a hole in the potting mix that is large enough to accommodate the root ball. Place the seedling in the hole and backfill with potting mix. Space seedlings about 6-8 inches apart in the container.
4. Water Thoroughly: After planting, water the containers thoroughly until water drains out of the drainage holes. This will help settle the soil and ensure that the roots are well-hydrated.
5. Add Mulch (Optional): Apply a layer of mulch around the base of the plants to help retain moisture and suppress weeds.
6. Place in a Sunny Location: Kohlrabi needs at least 6 hours of sunlight per day. Place your containers in a location that receives plenty of sunshine.
Caring for Your Kohlrabi Plants
Now that your kohlrabi is planted, it’s time to provide the care it needs to thrive.
1. Watering: Kohlrabi needs consistent moisture to grow well. Water regularly, especially during hot, dry weather. Check the soil moisture by sticking your finger into the soil. If the top inch of soil feels dry, it’s time to water. Avoid overwatering, as this can lead to root rot.
2. Fertilizing: Kohlrabi is a heavy feeder, so it needs regular fertilization. Apply a balanced, water-soluble fertilizer every 2-3 weeks, following the instructions on the fertilizer package. Alternatively, you can use a slow-release fertilizer at planting time.
3. Thinning (if starting from seed): Once the seedlings have developed a few true leaves, thin them out to the strongest seedling per container or space them 6-8 inches apart.
4. Weeding: Keep the containers free of weeds, as they can compete with the kohlrabi for nutrients and water.
5. Pest and Disease Control: Kohlrabi is generally resistant to pests and diseases, but it can be susceptible to aphids, cabbage worms, and flea beetles. Inspect your plants regularly for signs of pests or diseases. If you find any, treat them promptly with an appropriate insecticide or fungicide. I prefer using organic options whenever possible, like neem oil or insecticidal soap.
6. Sunlight: Ensure your kohlrabi plants are getting at least 6 hours of direct sunlight daily. If you live in a particularly hot climate, some afternoon shade might be beneficial to prevent the bulbs from bolting (going to seed prematurely).
Harvesting Your Kohlrabi
The moment you’ve been waiting for! Kohlrabi is typically ready to harvest about 50-60 days after planting.
1. Check for Size: Harvest the kohlrabi when the bulbs are about 2-3 inches in diameter. If you let them get too large, they can become tough and woody.
2. Harvesting: To harvest, simply cut the bulb from the stem with a sharp knife. Leave about an inch of stem attached to the bulb.
3. Enjoy: You can eat the kohlrabi raw, cooked, or pickled. The leaves are also edible and can be used like collard greens.
Troubleshooting Common Problems
Even with the best care, you might encounter a few challenges along the way. Here are some common problems and how to address them:
* Bolting (Premature Flowering): Bolting can occur if the plants are stressed by heat, drought, or poor soil. To prevent bolting, provide consistent moisture, fertilize regularly, and protect the plants from extreme heat.
* Cracking Bulbs: Cracking can be caused by inconsistent watering. Make sure to water regularly and avoid letting the soil dry out completely.
* Pest Infestations: As mentioned earlier, aphids, cabbage worms, and flea beetles can sometimes attack kohlrabi. Inspect your plants regularly and treat any infestations promptly.
* Slow Growth: Slow growth can be caused by a lack of nutrients, insufficient sunlight, or poor soil drainage. Make sure to fertilize regularly, provide plenty of sunlight, and use a well-draining potting mix.
Tips for Success
Here are a few extra tips to help you succeed with your kohlrabi container garden:
* Succession Planting: Plant kohlrabi every few weeks to ensure a continuous harvest throughout the growing season.
* Companion Planting: Plant kohlrabi with companion plants such as dill, chamomile, and mint to help deter pests and attract beneficial insects.
* Choose the Right Container Size: Ensure your container is large enough to accommodate the mature size of the kohlrabi variety you’re growing.
* Monitor Soil Moisture: Regularly check the soil moisture and water accordingly.
* Don’t Overcrowd: Give your kohlrabi plants enough space to grow and thrive.

Frequently Asked Questions (FAQ)
What is the best container size for growing kohlrabi?
A container that is at least 12 inches deep and 12 inches in diameter is generally recommended for growing kohlrabi. This provides enough space for the roots to develop properly. If you’re planning to grow multiple kohlrabi plants in the same container, choose a larger container accordingly, allowing at least 6-8 inches of space between plants. Remember, adequate space is crucial for healthy bulb development. Smaller containers can restrict root growth, leading to smaller bulbs and potentially stressed plants.
How much sunlight does kohlrabi need?
Kohlrabi thrives in full sun, which means it needs at least 6-8 hours of direct sunlight per day. If you’re growing kohlrabi indoors or in a partially shaded area, you may need to supplement with artificial lighting, such as grow lights. Insufficient sunlight can result in leggy growth and reduced bulb size. Observe your plants closely and adjust their position as needed to ensure they’re getting enough light. A sunny windowsill or a balcony with southern exposure are ideal locations.
What type of soil is best for growing kohlrabi in containers?
A well-draining potting mix is essential for growing kohlrabi in containers. Avoid using garden soil, as it can become compacted and waterlogged in containers. Look for a potting mix that is specifically formulated for vegetables or containers. You can also amend your potting mix with compost or other organic matter to improve its fertility and drainage. The ideal soil pH for kohlrabi is between 6.0 and 7.5.
How often should I water kohlrabi in containers?
Kohlrabi needs consistent moisture to thrive, but it’s important to avoid overwatering, which can lead to root rot. Water your kohlrabi plants when the top inch of soil feels dry to the touch. Water deeply, until water drains out of the bottom of the container. During hot, dry weather, you may need to water more frequently. Check the soil moisture regularly and adjust your watering schedule accordingly. Mulching around the base of the plants can help retain moisture and reduce the need for frequent watering.
What are some common pests and diseases that affect kohlrabi?
Common pests that can affect kohlrabi include aphids, cabbage worms, and flea beetles. You can control these pests by handpicking them off the plants, using insecticidal soap, or applying Bacillus thuringiensis (Bt). Common diseases that can affect kohlrabi include clubroot and downy mildew. To prevent these diseases, choose disease-resistant varieties, practice crop rotation, and avoid overwatering. Ensure good air circulation around the plants to minimize the risk of fungal diseases.
When is the best time to harvest kohlrabi?
Kohlrabi is typically ready to harvest when the bulb is about 2-3 inches in diameter. The exact timing will depend on the variety and growing conditions. Harvest kohlrabi when it’s young and tender, as it can become tough and woody if left to grow too large. To harvest, simply cut the bulb from the stem just above the soil line. You can also harvest the leaves, which are edible and can be used in salads or cooked like spinach.
Can I grow kohlrabi indoors?
Yes, you can grow kohlrabi indoors, but it requires a lot of light. You’ll need to provide at least 6-8 hours of direct sunlight per day or supplement with grow lights. Choose a compact variety that is well-suited for container growing. Make sure to provide adequate ventilation and monitor for pests and diseases. Indoor growing can be a great option for extending the growing season or for those who live in climates with harsh winters.
How can I prevent kohlrabi bulbs from cracking?
Cracking in kohlrabi bulbs is often caused by inconsistent watering. To prevent cracking, ensure that your plants receive consistent moisture, especially during periods of rapid growth. Avoid letting the soil dry out completely and then overwatering. Mulching around the base of the plants can help retain moisture and prevent fluctuations in soil moisture levels.
What are some creative ways to use kohlrabi in cooking?
Kohlrabi is a versatile vegetable that can be used in a variety of dishes. It can be eaten raw, grated into salads, or sliced and served with dips. It can also be cooked, steamed, roasted, or stir-fried. Kohlrabi has a mild, slightly sweet flavor that pairs well with other vegetables, herbs, and spices. Try adding it to soups, stews, or gratins. The leaves can also be used in salads or cooked like spinach. Experiment with different recipes and find your favorite ways to enjoy this delicious vegetable.
Can I save seeds from my kohlrabi plants?
Saving seeds from kohlrabi is possible, but it requires allowing the plant to bolt (flower and produce seeds). Kohlrabi is a biennial, meaning it takes two years to complete its life cycle. In the first year, it produces the bulb that we eat. In the second year, it will bolt and produce seeds. However, kohlrabi is cross-pollinated, so if you’re growing multiple varieties, the seeds may not be true to type. To ensure true-to-type seeds, you’ll need to isolate the plants or hand-pollinate them. Seed saving can be a rewarding way to preserve your favorite varieties and save money on seeds in the future.
