Growing Purple Kohlrabi in a Terrace Garden: A DIY Guide
Hey there, fellow gardening enthusiasts! I’m so excited to share my experience growing vibrant purple kohlrabi right here on my terrace. It’s surprisingly easy, even if you’re a beginner like I was not too long ago. Kohlrabi, with its unique flavor and striking color, is a fantastic addition to any garden, and a terrace is a perfectly viable space to cultivate it. Let’s dive into how you can grow your own beautiful and delicious purple kohlrabi!
What You’ll Need
Before we get started, let’s gather all the necessary supplies. Having everything ready beforehand will make the process smooth and enjoyable.
* Kohlrabi Seeds (Purple Vienna or similar variety): Choose a reputable seed supplier for the best germination rates.
* Seed Starting Tray or Small Pots: These will be used to germinate the seeds indoors.
* Seed Starting Mix: A light and airy mix specifically designed for seedlings.
* Larger Pots or Containers (at least 12 inches in diameter): Kohlrabi needs space to grow, so choose appropriately sized containers.
* Potting Soil: A well-draining potting mix rich in organic matter.
* Slow-Release Fertilizer: This will provide essential nutrients throughout the growing season.
* Watering Can or Hose: For regular watering.
* Trowel or Small Shovel: For transplanting seedlings.
* Gardening Gloves: To protect your hands.
* Optional: Row Covers or Netting: To protect against pests like cabbage moths.
Starting Your Kohlrabi Seeds Indoors
Starting your kohlrabi seeds indoors gives them a head start, especially if you live in an area with a shorter growing season. I’ve found this method to be incredibly effective.
1. Prepare Your Seed Starting Tray: Fill your seed starting tray or small pots with seed starting mix. Gently pat it down to remove any air pockets.
2. Sow the Seeds: Sow 2-3 kohlrabi seeds per cell or pot, about ¼ inch deep.
3. Water Gently: Water the soil gently using a watering can or spray bottle. Avoid overwatering, as this can lead to damping-off disease.
4. Provide Warmth and Light: Place the tray or pots in a warm location (around 65-75°F) with plenty of light. A sunny windowsill or a grow light works well.
5. Keep the Soil Moist: Keep the soil consistently moist, but not soggy. Check the moisture level daily and water as needed.
6. Thin the Seedlings: Once the seedlings emerge and have a couple of true leaves (the second set of leaves), thin them to one strong seedling per cell or pot. Snip off the weaker seedlings at the soil line with scissors.
Transplanting Your Kohlrabi Seedlings
Once your seedlings are strong enough, it’s time to transplant them into their permanent containers on your terrace.
1. Harden Off the Seedlings: Before transplanting, you need to “harden off” the seedlings. This means gradually exposing them to outdoor conditions over a period of 7-10 days. Start by placing them outside for an hour or two each day, gradually increasing the time they spend outdoors. This will help them adjust to the sun, wind, and temperature changes.
2. Prepare Your Containers: Fill your larger pots or containers with potting soil. Make sure the containers have drainage holes to prevent waterlogging.
3. Transplant the Seedlings: Gently remove the seedlings from their cells or pots. Be careful not to damage the roots. Dig a hole in the potting soil large enough to accommodate the root ball. Place the seedling in the hole and gently backfill with soil.
4. Water Thoroughly: Water the transplanted seedlings thoroughly.
5. Add Slow-Release Fertilizer: Sprinkle a slow-release fertilizer around the base of the plants, following the instructions on the fertilizer package.
6. Mulch (Optional): Add a layer of mulch around the plants to help retain moisture and suppress weeds.
Caring for Your Kohlrabi Plants
Now that your kohlrabi plants are in their permanent homes, it’s important to provide them with the care they need to thrive.
1. Watering: Kohlrabi needs consistent moisture to grow well. Water deeply whenever the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.
2. Sunlight: Kohlrabi needs at least 6 hours of sunlight per day. Choose a sunny spot on your terrace for your containers.
3. Fertilizing: In addition to the slow-release fertilizer you added at transplanting, you can also feed your kohlrabi plants with a liquid fertilizer every 2-3 weeks. Choose a fertilizer that is high in potassium, which promotes bulb development.
4. Pest Control: Kohlrabi can be susceptible to pests like cabbage moths, aphids, and flea beetles. Inspect your plants regularly for signs of infestation. You can use row covers or netting to protect your plants from cabbage moths. For aphids and flea beetles, you can try spraying them with insecticidal soap or neem oil.
5. Weed Control: Keep the area around your kohlrabi plants free of weeds. Weeds compete with the plants for nutrients and water.
Harvesting Your Kohlrabi
The best part of growing kohlrabi is, of course, harvesting and enjoying your delicious crop!
1. Harvest Time: Kohlrabi is typically ready to harvest 50-60 days after planting. The bulb should be about 2-3 inches in diameter.
2. How to Harvest: To harvest kohlrabi, simply cut the bulb from the stem with a sharp knife.
3. 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:
* Splitting Bulbs: Splitting bulbs can be caused by inconsistent watering. Make sure to water your kohlrabi plants regularly and deeply, especially during dry spells.
* Woody Bulbs: Woody bulbs can be caused by harvesting the kohlrabi too late. Harvest the bulbs when they are 2-3 inches in diameter for the best flavor and texture.
* Pest Infestations: As mentioned earlier, kohlrabi can be susceptible to pests. Inspect your plants regularly and take action to control any infestations.
Enjoying Your Homegrown Kohlrabi
Now that you’ve harvested your beautiful purple kohlrabi, it’s time to enjoy it! Kohlrabi can be eaten raw or cooked. It has a mild, slightly sweet flavor and a crisp texture.
* Raw: You can slice or dice kohlrabi and add it to salads, slaws, or crudités platters.
* Cooked: Kohlrabi can be steamed, roasted, sautéed, or added to soups and stews.
I personally love to roast kohlrabi with a little olive oil, salt, and pepper. It’s a simple and delicious way to enjoy this unique vegetable. The leaves are also edible and can be cooked like spinach or kale.
Choosing the Right Variety
While this guide focuses on purple kohlrabi, specifically the ‘Purple Vienna’ variety, there are other options available. Experimenting with different varieties can be a fun way to discover your favorite. Some popular choices include:
* White Vienna: A classic green variety with a mild flavor.
* Grand Duke: A fast-growing variety that is resistant to bolting (going to seed prematurely).
* Superschmelz: A giant variety that can grow to be quite large, but still retains a good flavor.
Optimizing Your Terrace Garden for Kohlrabi
To maximize your kohlrabi harvest on your terrace, consider these tips:
* Container Size: Ensure your containers are large enough. A minimum of 12 inches in diameter is recommended to allow for proper root development.
* Soil Quality: Use a high-quality potting mix that is well-draining and rich in organic matter. Amend the soil with compost or other organic materials to improve its fertility.
* Sunlight Exposure: Position your kohlrabi plants in a location that receives at least 6 hours of direct sunlight per day.
* Air Circulation: Good air circulation is important to prevent fungal diseases. Space your containers adequately to allow for airflow around the plants.
* Vertical Gardening: If space is limited, consider using vertical gardening techniques to maximize your growing area. You can train kohlrabi plants to grow up trell

To prevent these diseases, choose disease-resistant varieties, practice crop rotation, and avoid overhead watering. Ensure good air circulation around your plants to prevent fungal diseases.
Q: How do I know when my purple kohlrabi is ready to harvest?
A: Purple kohlrabi is typically ready to harvest when the bulb reaches a diameter of 2-3 inches. The exact size will depend on the variety you’re growing. The bulb should feel firm and smooth to the touch. Avoid letting the bulb grow too large, as it can become tough and woody. To harvest, simply cut the bulb from the stem using a sharp knife.
Q: Can I grow purple kohlrabi in the winter on my terrace?
A: Whether you can grow purple kohlrabi in the winter depends on your climate. Kohlrabi is a cool-season crop that can tolerate light frost. If you live in a mild climate with temperatures that don’t drop below freezing for extended periods, you may be able to grow purple kohlrabi throughout the winter. However, if you live in a colder climate, you’ll need to protect your plants from frost by covering them with row covers or bringing them indoors.
Q: What are some good companion plants for purple kohlrabi?
A: Good companion plants for purple kohlrabi include marigolds, nasturtiums, dill, chamomile, and onions. Marigolds and nasturtiums help deter pests, while dill and chamomile attract beneficial insects. Onions can help repel cabbage moths. Avoid planting kohlrabi near other members of the brassica family, such as broccoli, cabbage, and cauliflower, as they can attract the same pests and diseases.
Q: Can I eat the leaves of purple kohlrabi?
A: Yes, the leaves of purple kohlrabi are edible and nutritious. They have a similar flavor to kale or collard greens. You can eat them raw in salads or cooked in stir-fries, soups, or stews. Choose young, tender leaves for the best flavor and texture.
Q: How do I store harvested purple kohlrabi?
A: Store harvested purple kohlrabi in the refrigerator for up to several weeks. Remove the leaves before storing, as they can draw moisture from the bulb. Wrap the bulb in a plastic bag or store it in a container to prevent it from drying out.
Q: My purple kohlrabi is bolting (going to seed). What can I do?
A: Bolting occurs when kohlrabi is exposed to stress, such as high temperatures or inconsistent watering. Once kohlrabi bolts, the bulb becomes tough and bitter. Unfortunately, there’s not much you can do to reverse bolting. To prevent bolting, choose bolt-resistant varieties, provide consistent watering, and protect your plants from extreme temperatures. If your kohlrabi bolts, you can still harvest the leaves and use them in cooking.
