Growing Kohlrabi: A Beginner’s Guide to This Underrated Veggie
Hey there, fellow gardening enthusiasts! I’m so excited to share my experience growing kohlrabi. It’s a vegetable that often gets overlooked, but trust me, it’s incredibly rewarding to grow and delicious to eat. Think of it as a cross between a turnip and a cabbage, with a mild, slightly sweet flavor. Plus, it’s packed with nutrients! So, let’s dive into how you can grow your own kohlrabi at home.
Choosing Your Kohlrabi Variety
Before we get our hands dirty, let’s talk about kohlrabi varieties. There are a few popular choices, and your selection will depend on your climate and personal preference.
* Early White Vienna: This is a classic, fast-maturing variety that’s perfect for early harvests. It produces pale green bulbs.
* Early Purple Vienna: Similar to the White Vienna, but with a beautiful purple hue. It adds a pop of color to your garden!
* Grand Duke: A hybrid variety known for its excellent disease resistance and large, uniform bulbs.
* Gigante: As the name suggests, this variety produces exceptionally large bulbs, but it can take longer to mature.
I personally love growing both Early White and Early Purple Vienna for the variety and the visual appeal.
Getting Started: Planting Kohlrabi
Kohlrabi is a cool-season crop, which means it thrives in cooler temperatures. Timing is key to a successful harvest.
* When to Plant:
* Spring Planting: Start seeds indoors 4-6 weeks before the last expected frost. You can also direct sow seeds outdoors 2-3 weeks before the last frost.
* Fall Planting: Direct sow seeds outdoors 6-8 weeks before the first expected frost.
* Where to Plant: Kohlrabi needs at least 6 hours of sunlight per day. Choose a location in your garden that receives plenty of sun.
* Soil Preparation: Kohlrabi prefers well-drained, fertile soil with a pH between 6.0 and 7.5. Amend your soil with compost or well-rotted manure to improve drainage and fertility.
Step-by-Step Planting Guide
Now, let’s get down to the nitty-gritty of planting.
1. Starting Seeds Indoors (Optional):
* Fill seed trays or small pots with a seed-starting mix.
* Sow seeds about 1/4 inch deep.
* Water gently and keep the soil consistently moist.
* Place the trays in a warm location (around 70°F) or use a heat mat.
* Once the seedlings emerge (usually within 5-7 days), move them to a sunny location or under grow lights.
* Thin the seedlings to one plant per cell or pot.
* Harden off the seedlings by gradually exposing them to outdoor conditions for a week before transplanting.
2. Direct Sowing Seeds Outdoors:
* Prepare the soil by removing any weeds and rocks.
* Create shallow furrows about 1/2 inch deep.
* Sow seeds about 1 inch apart in the furrows.
* Cover the seeds with soil and water gently.
* Once the seedlings emerge, thin them to 4-6 inches apart.
3. Transplanting Seedlings:
* Dig holes that are slightly larger than the root balls of the seedlings.
* Gently remove the seedlings from their containers.
* Place the seedlings in the holes and backfill with soil.
* Space the plants 4-6 inches apart.
* Water thoroughly after transplanting.
Caring for Your Kohlrabi Plants
Once your kohlrabi plants are in the ground, it’s important to provide them with the care they need to thrive.
* Watering: Kohlrabi needs consistent moisture, especially during bulb development. Water deeply whenever the top inch of soil feels dry. Avoid overwatering, as this can lead to rot.
* Fertilizing: Feed your kohlrabi plants with a balanced fertilizer every 2-3 weeks. I like to use a liquid fertilizer diluted to half strength.
* Weeding: Keep the area around your kohlrabi plants free of weeds. Weeds compete with the plants for nutrients and water.
* Mulching: Apply a layer of mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature. Straw, wood chips, or shredded leaves work well.
* Pest Control: Kohlrabi can be susceptible to pests like cabbage worms, aphids, and flea beetles.
* Cabbage Worms: Handpick them off the plants or use Bacillus thuringiensis (Bt), a natural insecticide.
* Aphids: Spray the plants with a strong stream of water or use insecticidal soap.
* Flea Beetles: Cover the plants with row covers or use diatomaceous earth.
Harvesting Your Kohlrabi
The best part of growing kohlrabi is, of course, the harvest!
* When to Harvest: Kohlrabi is typically ready to harvest 50-60 days after planting. The bulbs should be about 2-3 inches in diameter. Don’t let them get too large, as they can become tough and woody.
* How to Harvest: Use a sharp knife to cut the bulb from the stem just above the soil line.
* Storing Kohlrabi: Remove the leaves and store the bulbs in the refrigerator for up to several weeks. The leaves are also edible and can be cooked like spinach or kale.
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:
* Bolting (Premature Flowering): Bolting can occur if the plants are exposed to extreme temperature fluctuations or stress. To prevent bolting, choose bolt-resistant varieties, provide consistent watering, and protect the plants from extreme heat or cold.
* Cracking Bulbs: Cracking can be caused by inconsistent watering or rapid growth. Ensure consistent watering and avoid over-fertilizing.
* Pest Damage: As mentioned earlier, kohlrabi can be susceptible to pests. Regularly inspect your plants for signs of infestation and take appropriate action.
Delicious Ways to Enjoy Your Kohlrabi
Now that you’ve harvested your kohlrabi, it’s time to enjoy the fruits (or rather, vegetables) of your labor! Kohlrabi is incredibly versatile and can be eaten raw or cooked.
* Raw: Peel the bulb and slice it thinly. It’s delicious in salads, slaws, or as a crunchy snack.
* Roasted: Toss kohlrabi cubes with olive oil, salt, and pepper, and roast them in the oven until tender and slightly caramelized.
* Steamed: Steam kohlrabi until tender and serve it with butter or your favorite sauce.
* Mashed: Mash cooked kohlrabi with potatoes or other root vegetables for a creamy and flavorful side dish.
* Stir-fried: Add kohlrabi to stir-fries for a crunchy and nutritious addition.
* Kohlrabi Fries: Cut kohlrabi into fry shapes, toss with oil and spices, and bake until crispy.
I personally love grating kohlrabi into salads for a refreshing crunch. I also enjoy roasting it with other root vegetables for a hearty and flavorful side dish. Don’t forget the leaves! They’re great sautéed with garlic and olive oil.
Tips for a Bountiful Harvest
Here are a few extra tips to help you maximize your kohlrabi harvest:
* Succession Planting: Plant kohlrabi seeds every 2-3 weeks to ensure a continuous harvest throughout the growing season.
* Choose the Right Variety: Select varieties that are well-suited to your climate and growing conditions.
* Provide Adequate Sunlight: Kohlrabi needs at least 6 hours of sunlight per day.
* Maintain Consistent Moisture: Water deeply and regularly, especially during bulb development.
* Fertilize Regularly: Feed your plants with a balanced fertilizer every 2-3 weeks.
* Protect from Pests: Regularly inspect your plants for pests and take appropriate action.
* Harvest at the Right Time: Harvest the bulbs when they are 2-3 inches in diameter to ensure the best flavor and texture.
Growing kohlrabi is a fun and rewarding experience. With a little bit of planning and care, you can enjoy a bountiful harvest of this delicious and nutritious vegetable. So, get out there and start planting! Happy gardening!
