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 these quirky, delicious veggies 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 You’ll Need
Before we dive into the nitty-gritty, let’s gather our supplies. Here’s a checklist of everything you’ll need to successfully grow kohlrabi in small spaces:
* Kohlrabi Seeds: Choose a variety that matures quickly. ‘Early White Vienna’ and ‘Early Purple Vienna’ are popular choices.
* Containers: Opt for pots that are at least 6-8 inches deep and wide. One plant per pot is ideal, but you can squeeze two into a larger container (12 inches or more).
* Potting Mix: Use a high-quality, well-draining potting mix. Avoid garden soil, as it can compact in containers.
* Fertilizer: A balanced, slow-release fertilizer is perfect. Alternatively, you can use a liquid fertilizer every few weeks.
* Watering Can or Hose: For regular watering.
* Trowel: For planting and transplanting.
* Sunlight: Kohlrabi needs at least 6 hours of sunlight per day.
* Optional:
* Seed starting tray and dome (if starting seeds indoors).
* Plant labels.
* Mulch (straw or wood chips).
Getting Started: Sowing the Seeds
You have two options here: direct sowing or starting seeds indoors. I personally prefer starting seeds indoors because it gives me a head start, especially if I live in an area with a shorter growing season.
Option 1: Starting Seeds Indoors
1. Prepare Your Seed Starting Tray: Fill your seed starting tray with a seed starting mix. This mix is lighter than potting mix and helps the delicate seedlings emerge easily.
2. Sow the Seeds: Make small indentations (about ¼ inch deep) in each cell of the tray. Place 2-3 kohlrabi seeds in each indentation.
3. Cover and Water: Gently cover the seeds with more seed starting mix and water thoroughly using a spray bottle. You want the soil to be moist but not soggy.
4. Provide Warmth and Light: Cover the tray with a humidity dome to create a warm, moist environment. Place the tray in a warm location (around 70°F) and under grow lights or near a sunny window.
5. Monitor and Water: Check the tray daily and water as needed to keep the soil moist. Once the seedlings emerge (usually within 5-7 days), remove the humidity dome.
6. Thin the Seedlings: Once the seedlings have their first true leaves (the second set of leaves), thin them to one strong seedling per cell. Snip off the weaker seedlings at the soil line with scissors.
7. Harden Off the Seedlings: Before transplanting the seedlings outdoors, you need to “harden them off.” This process gradually acclimates them to outdoor conditions. Start by placing the tray outdoors in a sheltered location for an hour or two each day, gradually increasing the time over the course of a week.
Option 2: Direct Sowing
1. Prepare Your Containers: Fill your containers with a high-quality potting mix, leaving about an inch of space at the top.
2. Sow the Seeds: Make small indentations (about ½ inch deep) in the soil. Place 2-3 kohlrabi seeds in each indentation.
3. Cover and Water: Gently cover the seeds with soil and water thoroughly.
4. Thin the Seedlings: Once the seedlings emerge and have their first true leaves, thin them to one strong seedling per container (or two if you’re using a larger container).
Transplanting and Growing
Whether you started your seeds indoors or direct sowed, the next step is to ensure your kohlrabi has the best possible growing conditions.
1. Choose the Right Location: Kohlrabi needs at least 6 hours of sunlight per day. Choose a location that receives plenty of sun. If you’re growing on a balcony or patio, make sure it’s not shaded by buildings or trees.
2. Transplant Seedlings (if applicable): Gently remove the seedlings from the seed starting tray. Dig a small hole in the center of your container and carefully place the seedling in the hole. Backfill with potting mix and gently firm the soil around the base of the plant.
3. Water Regularly: Kohlrabi needs consistent moisture to thrive. Water deeply whenever the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.
4. Fertilize: Feed your kohlrabi plants every 2-3 weeks with a balanced liquid fertilizer. Alternatively, you can incorporate a slow-release fertilizer into the potting mix at planting time.
5. Mulch (Optional): Applying a layer of mulch (such as straw or wood chips) around the base of the plants can help retain moisture, suppress weeds, and regulate soil temperature.
6. Monitor for Pests and Diseases: Keep an eye out for common pests like aphids, cabbage worms, and flea beetles. You can control these pests with insecticidal soap or neem oil. Kohlrabi is also susceptible to diseases like clubroot and downy mildew. Ensure good air circulation and avoid overwatering to prevent these diseases.
Harvesting Your Kohlrabi
This is the most exciting part! Kohlrabi is typically ready to harvest about 50-60 days after planting, depending on the variety.
1. Check for Size: The ideal size for harvesting kohlrabi is about 2-3 inches in diameter. If you let them grow too large, they can become tough and woody.
2. Harvest Carefully: Use a sharp knife to cut the kohlrabi bulb from the stem, just above the soil line.
3. Remove the Leaves: Remove the leaves from the bulb. You can eat the leaves, too! They taste similar to kale or collard greens.
4. Store Properly: Store kohlrabi bulbs in the refrigerator for up to several weeks.
Troubleshooting Tips
Even with the best planning, sometimes things don’t go exactly as expected. Here are a few common problems you might encounter and how to fix them:
* Leggy Seedlings: If your seedlings are tall and spindly, they’re not getting enough light. Move them to a sunnier location or provide supplemental light with grow lights.
* Yellowing Leaves: Yellowing leaves can indicate a nutrient deficiency. Try fertilizing with a balanced fertilizer.
* Pest Infestation: If you notice pests on your plants, treat them with insecticidal soap or neem oil.
* Slow Growth: Slow growth can be caused by a variety of factors, including lack of sunlight, poor soil, or insufficient watering. Make sure your plants are getting enough sun, water, and nutrients.
Kohlrabi Varieties to Consider
Choosing the right variety can make a big difference in your success, especially in small spaces. Here are a few of my favorites:
* Early White Vienna: A classic, fast-maturing variety with a mild flavor.
* Early Purple Vienna: Similar to Early White Vienna, but with a beautiful purple skin.
* Grand Duke: A hybrid variety that is known for its disease resistance and uniform growth.
* Kossak: A giant variety that can grow up to 10 pounds, but it still does well in containers if given enough space.
Enjoying Your Harvest
Now that you’ve successfully grown your own kohlrabi, it’s time to enjoy the fruits (or rather, vegetables) of your labor! Kohlrabi can be eaten raw or cooked.
* Raw: Peel the bulb and slice it thinly. It has a crisp, slightly sweet flavor that’s perfect for salads or snacking.
* Cooked: Kohlrabi can be steamed, roasted, stir-fried, or added to soups and stews. It has a similar texture to turnips or broccoli stems.
* Leaves: Don’t forget about the leaves! They can be cooked like kale or collard greens.
Growing kohlrabi in small spaces is a rewarding experience. With a little planning and effort, you can enjoy fresh, homegrown vegetables even if you don’t have a lot of space. Happy gardening!

Frequently Asked Questions (FAQ)
What is the best time of year to plant kohlrabi in a small space?
The ideal time to plant kohlrabi depends on your local climate. Generally, it’s best to plant kohlrabi in early spring or late summer for a fall harvest. Kohlrabi prefers cooler temperatures, so avoid planting during the hottest months of the year. In warmer climates, you can often grow kohlrabi throughout the winter. Check your local frost dates and plan accordingly. For a spring crop, start seeds indoors 4-6 weeks before the last expected frost. For a fall crop, sow seeds directly into your containers in late summer.
How much sunlight does kohlrabi need when grown in containers?
Kohlrabi thrives in full sun, which means at least 6 hours of direct sunlight per day. If you’re growing kohlrabi on a balcony or patio, choose a location that receives ample sunlight. If you don’t have enough natural sunlight, you can supplement with grow lights. Position the grow lights about 6-12 inches above the plants and provide 14-16 hours of light per day. Rotate your containers regularly to ensure that all sides of the plants receive adequate sunlight.
What type of soil is best for growing kohlrabi in pots?
Kohlrabi prefers well-draining, fertile soil with a pH between 6.0 and 7.5. A good potting mix is essential for container gardening.
