Growing Kohlrabi at Home: A Beginner’s Guide
Kohlrabi, sometimes called a German turnip, is a unique and delicious vegetable that’s surprisingly easy to grow at home. Don’t let its alien-like appearance intimidate you! It’s a member of the cabbage family and tastes like a mild, sweet turnip or broccoli stem. I’ve found it incredibly rewarding to grow my own, and I’m excited to share my tips and tricks with you.
Choosing Your Kohlrabi Variety
Before we dive into the nitty-gritty, let’s talk about kohlrabi varieties. This is important because different varieties mature at different rates and have slightly different flavors. Here are a few popular choices:
* Early White Vienna: This is a classic, fast-maturing variety that’s perfect for beginners. It produces pale green bulbs with a mild flavor.
* Early Purple Vienna: Similar to the White Vienna, but with a beautiful purple skin. The flesh is still white and the flavor is comparable.
* Grand Duke: A hybrid variety known for its disease resistance and large, uniform bulbs.
* Kossak: This is a giant variety that can grow to be quite large without becoming woody or tough. If you want bragging rights, this is the one to try!
* White Delicacy: As the name suggests, this variety is known for its delicate flavor and tender texture.
I personally prefer the Early White Vienna because it’s reliable and matures quickly, allowing me to get multiple harvests in a single season.
When to Plant Kohlrabi
Timing is crucial for successful kohlrabi growing. Kohlrabi thrives in cool weather, so you’ll want to plant it either in early spring or late summer for a fall harvest.
* 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, but be prepared to protect them from unexpected cold snaps.
* Fall Planting: Direct sow seeds outdoors 6-8 weeks before the first expected frost. This will give your kohlrabi enough time to mature before the weather gets too cold.
I usually start my spring kohlrabi indoors to get a head start, and then direct sow my fall crop. This gives me a continuous supply of fresh kohlrabi throughout the growing season.
Preparing the Soil
Kohlrabi needs well-drained, fertile soil to thrive. Before planting, amend your soil with plenty of compost or well-rotted manure. This will improve drainage, add nutrients, and help retain moisture.
* Soil pH: Kohlrabi prefers a soil pH between 6.0 and 7.5. You can test your soil pH with a simple soil testing kit from your local garden center. If your soil is too acidic, you can add lime to raise the pH.
* Sunlight: Kohlrabi needs at least 6 hours of sunlight per day. Choose a location in your garden that receives plenty of sun.
* Drainage: Make sure your soil drains well. Kohlrabi doesn’t like to sit in soggy soil, which can lead to root rot.
I always add a generous amount of compost to my kohlrabi bed before planting. It makes a huge difference in the size and quality of the bulbs.
Planting Kohlrabi: Step-by-Step
Now for the fun part – planting! Whether you’re starting from seeds or transplants, here’s how to get your kohlrabi off to a good start:
1. Starting Seeds Indoors (Optional): Fill seed trays or small pots with seed-starting mix. Sow seeds about ¼ inch deep and water gently. Keep the soil moist but not soggy. Place the trays in a warm, sunny location or under grow lights. Once the seedlings have developed a few true leaves, you can transplant them outdoors.
2. Direct Sowing Seeds Outdoors: Sow seeds about ½ inch deep and 1-2 inches apart in rows that are 12-18 inches apart. Gently water the soil and keep it moist until the seeds germinate.
3. Transplanting Seedlings: Harden off your seedlings by gradually exposing them to outdoor conditions for a week before transplanting. Dig holes that are slightly larger than the root balls of the seedlings. Space the seedlings 6-8 inches apart in rows that are 12-18 inches apart. Gently remove the seedlings from their pots and place them in the holes. Backfill with soil and water thoroughly.
4. Mulching: Apply a layer of mulch around your kohlrabi plants. This will help retain moisture, suppress weeds, and keep the soil cool. I like to use straw or shredded leaves as mulch.
Caring for Your Kohlrabi Plants
Once your kohlrabi plants are in the ground, it’s important to provide them with proper care to ensure a bountiful harvest.
* Watering: Kohlrabi needs consistent moisture to grow properly. Water deeply and regularly, especially during dry spells. Aim for about 1 inch of water per week.
* Fertilizing: Kohlrabi is a heavy feeder, so it benefits from regular fertilization. You can use a balanced fertilizer or side-dress with compost or well-rotted manure. I like to use a liquid seaweed fertilizer every few weeks.
* Weeding: Keep your kohlrabi bed free of weeds. Weeds compete with kohlrabi for nutrients and water, so it’s important to remove them regularly.
* Pest Control: Kohlrabi can be susceptible to pests such as cabbage worms, aphids, and flea beetles. Inspect your plants regularly for signs of pests and take action if necessary. You can use insecticidal soap, neem oil, or row covers to protect your plants. I prefer using row covers because they’re a natural and effective way to keep pests away.
* Thinning: If you direct sowed your kohlrabi seeds, you’ll need to thin the seedlings once they’re a few inches tall. Thin them to 6-8 inches apart to give them enough room to grow.
Harvesting Kohlrabi
The best part of growing kohlrabi is, of course, harvesting and eating it! Kohlrabi is typically ready to harvest 6-8 weeks after planting.
* When to Harvest: Harvest kohlrabi when the bulbs are about 2-3 inches in diameter. If you let them grow too large, they can become woody and tough.
* How to Harvest: Use a sharp knife to cut the bulb from the stem just above the soil line. You can also pull the entire plant out of the ground.
* Storing Kohlrabi: Remove the leaves from the bulbs and store them separately in the refrigerator. The bulbs will keep for several weeks in the refrigerator. The leaves can be used like collard greens or kale.
I love to eat kohlrabi raw, sliced thinly in salads or as a snack with hummus. It’s also delicious roasted, stir-fried, or added to soups and stews.
Troubleshooting Common Kohlrabi 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: Bolting is when kohlrabi plants prematurely flower and go to seed. This can happen if the weather gets too hot or if the plants are stressed. To prevent bolting, choose bolt-resistant varieties, plant at the right time of year, and provide consistent moisture.
* Root Rot: Root rot is a fungal disease that can occur in poorly drained soil. To prevent root rot, make sure your soil drains well and avoid overwatering.
* Pest Infestations: As mentioned earlier, kohlrabi can be susceptible to pests. Inspect your plants regularly and take action if necessary.
Enjoying Your Homegrown Kohlrabi
Growing kohlrabi at home is a rewarding experience that allows you to enjoy fresh, delicious vegetables right from your own garden. With a little bit of planning and care, you can have a bountiful harvest of kohlrabi to enjoy in a variety of dishes.
