This guide is packed with tips and tricks I’ve learned over the years, so get ready to become a kohlrabi-growing expert!
Understanding Kohlrabi: The Basics
Before we dive into the nitty-gritty, let’s cover some essential kohlrabi knowledge.
* What is Kohlrabi? Kohlrabi (Brassica oleracea var. gongylodes) is a member of the cabbage family. The edible part is the swollen stem, which grows above ground. It comes in green, purple, and white varieties.
* Why Grow Kohlrabi? It’s delicious raw or cooked! Think salads, slaws, stir-fries, and even roasted dishes. Plus, it’s packed with vitamins and fiber.
* Timing is Key: Kohlrabi thrives in cool weather. Spring and fall are your best bets. Avoid planting in the heat of summer, as it can bolt (go to seed).
* Sunlight Needs: Kohlrabi needs at least 6 hours of sunlight per day.
* Soil Requirements: Well-drained, fertile soil with a pH between 6.0 and 7.5 is ideal.
Getting Started: Planting Kohlrabi
Okay, let’s get our hands dirty! Here’s how I start my kohlrabi plants.
1. Choose Your Variety: I personally love ‘Early White Vienna’ and ‘Purple Vienna’ for their flavor and early maturity. ‘Grand Duke’ is another excellent choice for larger bulbs.
2. Start Seeds Indoors (Optional): Starting seeds indoors gives you a head start, especially if you have a short growing season.
* When to Start: About 4-6 weeks before the last expected frost.
* How to Start: Use seed-starting trays or small pots filled with seed-starting mix. Sow seeds about ¼ inch deep.
* Keep Them Moist: Water gently and keep the soil consistently moist but not soggy.
* Provide Light: Place the trays under grow lights or in a sunny window.
* Harden Off: Before transplanting outdoors, gradually acclimate the seedlings to outdoor conditions over a week or so. This process is called “hardening off.”
3. Direct Sowing (My Preferred Method): Kohlrabi is surprisingly easy to direct sow, which saves time and effort.
* When to Sow: As soon as the soil can be worked in the spring, or about 4-6 weeks before the first expected frost in the fall.
* Prepare the Soil: Loosen the soil and amend it with compost or well-rotted manure. This will provide essential nutrients and improve drainage.
* Sow the Seeds: Plant seeds about ½ inch deep and 1 inch apart in rows.
* Water Gently: Keep the soil consistently moist until the seedlings emerge.
4. Thinning Seedlings: Once the seedlings have a few true leaves, thin them to about 4-6 inches apart. This gives them enough space to grow and prevents overcrowding. Don’t just yank them out! Gently snip them at the soil line to avoid disturbing the roots of the remaining plants.
5. Transplanting Seedlings (If Starting Indoors):
* Prepare the Soil: Just like with direct sowing, loosen the soil and amend it with compost.
* Dig Holes: Dig holes that are slightly larger than the root balls of the seedlings.
* Carefully Remove Seedlings: Gently remove the seedlings from their trays or pots, being careful not to damage the roots.
* Plant Seedlings: Place the seedlings in the holes and backfill with soil.
* Water Thoroughly: Water well after transplanting to help the seedlings settle in.
* Space Them Out: Space the plants 4-6 inches apart in rows that are 12-18 inches apart.
Nurturing Your Kohlrabi: Care and Maintenance
Now that your kohlrabi is planted, it’s time to give it some TLC.
1. Watering: Kohlrabi needs consistent moisture, especially during hot weather. Water deeply and regularly, aiming for about 1 inch of water per week. Avoid overhead watering, as it can promote fungal diseases. Drip irrigation or soaker hoses are excellent choices.
2. Fertilizing: Kohlrabi is a heavy feeder. I like to side-dress my plants with a balanced fertilizer (like 10-10-10) every 2-3 weeks. Alternatively, you can use compost tea or fish emulsion.
3. Weeding: Keep the area around your kohlrabi plants free of weeds. Weeds compete for nutrients and water, which can stunt the growth of your kohlrabi. Hand-weeding is best to avoid damaging the shallow roots of the kohlrabi.
4. Mulching: Apply a layer of mulch around your kohlrabi plants. Mulch helps to retain moisture, suppress weeds, and regulate soil temperature. Straw, wood chips, or shredded leaves are all good options.
5. Pest Control: Kohlrabi can be susceptible to pests like cabbage worms, aphids, and flea beetles.
* Cabbage Worms: These green caterpillars can devour the leaves of your kohlrabi. Hand-picking them off is an effective method. You can also use Bacillus thuringiensis (Bt), a natural insecticide.
* Aphids: These tiny insects suck the sap from plants. Spray them off with a strong stream of water or use insecticidal soap.
* Flea Beetles: These small, jumping beetles can create tiny holes in the leaves. Cover your plants with row covers to prevent them from reaching the kohlrabi. Diatomaceous earth can also be effective.
6. Preventing Bolting: Bolting (going to seed) is a common problem with kohlrabi, especially in hot weather. To prevent bolting:
* Plant at the Right Time: Avoid planting in the heat of summer.
* Provide Consistent Moisture: Water regularly to prevent stress.
* Choose Bolt-Resistant Varieties: Some varieties are more resistant to bolting than others.
Harvesting Kohlrabi: The Sweet Reward
The moment we’ve all been waiting for! Harvesting your delicious kohlrabi.
1. When to Harvest: Kohlrabi is best harvested when the bulb is about 2-3 inches in diameter. Larger bulbs can become tough and woody.
2. How to Harvest: Use a sharp knife to cut the bulb just above the soil line.
3. Remove the Leaves: Cut off the leaves, leaving about 1-2 inches of stem attached to the bulb. The leaves are also edible and can be cooked like spinach or kale.
4. Storage: Kohlrabi can be stored in the refrigerator for several weeks. Store the bulbs in a plastic bag or container to prevent them from drying out.
Troubleshooting: Common Kohlrabi Problems
Even with the best care, you might encounter some challenges. Here’s how to tackle them:
* Splitting Bulbs: This is often caused by inconsistent watering. Make sure to water regularly and deeply, especially during dry spells.
* Woody Texture: This can be caused by harvesting too late or by growing kohlrabi in hot weather. Harvest when the bulbs are young and tender.
* Lack of Bulb Formation: This can be caused by poor soil, insufficient sunlight, or overcrowding. Make sure to provide fertile soil, at least 6 hours of sunlight, and adequate spacing.
My Favorite Kohlrabi Recipes: Time to Eat!
Now that you’ve harvested your kohlrabi, it’s time to enjoy the fruits (or rather, vegetables) of your labor! Here are a few of my favorite ways to eat kohlrabi:
* Kohlrabi Slaw: Grate kohlrabi and carrots, then toss with a creamy dressing.
* Roasted Kohlrabi: Toss kohlrabi cubes with olive oil, salt, and pepper, then roast until tender.

Frequently Asked Questions (FAQ)
What is the best time of year to plant kohlrabi?
Kohlrabi is a cool-season crop, meaning it thrives in cooler temperatures. The best time to plant kohlrabi depends on your climate. In areas with mild winters, you can plant it in the fall for a winter harvest. In colder climates, plant it in early spring, about 4-6 weeks before the last expected frost. You can also plant a second crop in late summer for a fall harvest. Avoid planting during the hottest months of summer, as high temperatures can cause the kohlrabi to become tough and bolt (go to seed prematurely).
How much sunlight does kohlrabi need?
Kohlrabi needs at least 6 hours of direct sunlight per day to grow properly. Choose a location in your garden that receives full sun for the majority of the day. If you live in a particularly hot climate, some afternoon shade can be beneficial to prevent the plants from overheating.
What kind of soil is best for growing kohlrabi?
Kohlrabi prefers well-drained, fertile soil that is rich in organic matter. The ideal soil pH is between 6.0 and 7.5. Before planting, amend your soil with compost or well-rotted manure to improve its fertility and drainage. Avoid heavy clay soils, as they can become waterlogged and hinder root growth.
How often should I water kohlrabi?
Kohlrabi needs consistent moisture to grow quickly and develop tender bulbs. Water deeply and regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged. Mulching around the plants can help retain moisture and suppress weeds. A good rule of thumb is to water when the top inch of soil feels dry to the touch.
How do I fertilize kohlrabi?
Kohlrabi is a heavy feeder, so it benefits from regular fertilization. Before planting, incorporate a balanced fertilizer into the soil. During the growing season, side-dress the plants with a nitrogen-rich fertilizer every 2-3 weeks to promote leafy growth. Avoid over-fertilizing, as this can lead to excessive foliage and smaller bulbs.
When is kohlrabi ready to harvest?
Kohlrabi is typically ready to harvest 6-8 weeks after planting, depending on the variety. The bulbs should be about 2-3 inches in diameter. Don’t let them grow too large, as they can become tough and woody. To harvest, simply cut the bulb from the stem just above the soil line.
What are some common pests and diseases that affect kohlrabi?
Common pests that affect kohlrabi include cabbage worms, aphids, and flea beetles. You can control these pests with organic insecticides like neem oil or insecticidal soap. Diseases that can affect kohlrabi include clubroot and downy mildew. To prevent these diseases, practice crop rotation, ensure good drainage, and avoid overhead watering.
Can I grow kohlrabi in containers?
Yes, kohlrabi can be grown successfully in containers. Choose a container that is at least 12 inches deep and wide to allow enough room for the roots to grow. Use a well-draining potting mix and water regularly. Container-grown kohlrabi may need more frequent fertilization than plants grown in the ground.
How do I store kohlrabi after harvesting?
After harvesting, remove the leaves from the kohlrabi bulb and store them separately. The bulbs can be stored in the refrigerator for several weeks. The leaves can be stored in the refrigerator for a few days. To store kohlrabi for longer periods, you can freeze it. Blanch the bulbs and leaves in boiling water for a few minutes, then cool them in ice water before freezing.
What are some ways to eat kohlrabi?
Kohlrabi can be eaten raw or cooked. Raw kohlrabi has a crisp, slightly sweet flavor and can be grated into salads or used as a crudité. Cooked kohlrabi can be steamed, roasted, sautéed, or added to soups and stews. The leaves can be cooked like spinach or kale. Kohlrabi is a versatile vegetable that can be used in a variety of dishes.
