Grow Kohlrabi Easily: A DIY Guide for a Bountiful Harvest
Hey there, fellow gardening enthusiasts! I’m so excited to share my tried-and-true method for growing kohlrabi. This often-overlooked vegetable is surprisingly easy to cultivate, and the reward of fresh, crunchy bulbs is well worth the effort. Trust me, once you taste homegrown kohlrabi, you’ll be hooked! This guide will walk you through every step, from seed to table.
Why Grow Kohlrabi?
Before we dive in, let’s talk about why kohlrabi deserves a spot in your garden. It’s not just another pretty face (or bulb!).
* Nutrient-Packed: Kohlrabi is a nutritional powerhouse, loaded with Vitamin C, potassium, and fiber.
* Versatile in the Kitchen: You can eat the bulb raw, roasted, steamed, or even stir-fried. The leaves are also edible and taste similar to collard greens.
* Fast-Growing: Kohlrabi matures quickly, often in as little as 45-60 days, making it a great option for succession planting.
* Unique Flavor: The taste is mild and slightly sweet, reminiscent of a cross between a turnip and a cabbage.
* Pest Resistant: Generally, kohlrabi is less susceptible to pests than other members of the brassica family.
Getting Started: What You’ll Need
To embark on your kohlrabi-growing adventure, gather these essential supplies:
* Kohlrabi Seeds: Choose a variety that suits your climate and taste preferences. I personally love ‘Early White Vienna’ and ‘Purple Vienna’ for their reliable performance.
* Seed Starting Trays or Pots: If you’re starting seeds indoors.
* Seed Starting Mix: A light and airy mix specifically designed for seedlings.
* Garden Soil: Well-draining, fertile soil is crucial for healthy kohlrabi growth.
* Compost or Aged Manure: To enrich the soil and provide essential nutrients.
* Fertilizer: A balanced fertilizer (10-10-10) or one formulated for vegetables.
* Watering Can or Hose: For consistent watering.
* Gardening Gloves: To protect your hands.
* Trowel or Garden Fork: For planting and cultivating.
* Row Covers (Optional): To protect against pests and frost.
* Measuring Tape or Ruler: To ensure proper spacing.
Phase 1: Starting Your Seeds (Indoors or Direct Sowing)
You have two options for starting your kohlrabi: indoors or direct sowing. Starting indoors gives you a head start, especially in colder climates.
Starting Seeds Indoors:
1. Sow the Seeds: Fill your seed starting trays or pots with seed starting mix. Moisten the mix thoroughly. Sow the kohlrabi seeds about ¼ inch deep, placing 2-3 seeds per cell or pot.
2. Provide Warmth and Light: Kohlrabi seeds germinate best at temperatures between 65-75°F (18-24°C). Place the trays in a warm location or use a heat mat. Provide ample light, either from a sunny window or a grow light. If using a grow light, keep it a few inches above the seedlings and provide 14-16 hours of light per day.
3. Keep the Soil Moist: Water gently to keep the soil consistently moist but not waterlogged. Use a spray bottle or watering can with a gentle nozzle.
4. Thin the Seedlings: Once the seedlings emerge (usually in 5-7 days), thin them to one strong seedling per cell or pot. Snip off the weaker seedlings at the soil line with scissors.
5. Harden Off the Seedlings: About a week before transplanting, gradually acclimate the seedlings to outdoor conditions. Start by placing them outside for a few hours each day in a sheltered location, gradually increasing the time and exposure to sunlight.
Direct Sowing:
1. Prepare the Soil: Choose a sunny location with well-draining soil. Amend the soil with compost or aged manure to improve fertility and drainage.
2. Sow the Seeds: Sow the kohlrabi seeds about ½ inch deep, spacing them 1-2 inches apart in rows.
3. Water Gently: Water the soil gently to keep it moist.
4. Thin the Seedlings: Once the seedlings emerge, thin them to 4-6 inches apart.
Phase 2: Transplanting Your Kohlrabi Seedlings
Once your seedlings have developed a few sets of true leaves (about 4-6 weeks after sowing), they’re ready to be transplanted into the garden.
1. Prepare the Garden Bed: Choose a sunny location with well-draining soil. Amend the soil with compost or aged manure to improve fertility and drainage. Kohlrabi prefers a soil pH between 6.0 and 7.5.
2. Dig the Holes: Dig holes that are slightly larger than the root balls of your seedlings, spacing them 6-8 inches apart in rows. Allow 12-18 inches between rows.
3. Transplant the Seedlings: Gently remove the seedlings from their trays or pots, being careful not to damage the roots. Place each seedling in a hole and backfill with soil, gently firming around the base.
4. Water Thoroughly: Water the transplanted seedlings thoroughly to help them settle in.
5. Apply Fertilizer: Apply a balanced fertilizer (10-10-10) or one formulated for vegetables according to the package directions.
6. Add Mulch (Optional): Mulch around the plants with straw, wood chips, or shredded leaves to help retain moisture, suppress weeds, and regulate soil temperature.
Phase 3: Caring for Your Kohlrabi Plants
Consistent care is key to a successful kohlrabi harvest.
1. Water Regularly: Kohlrabi needs consistent moisture to thrive. Water deeply whenever the top inch of soil feels dry. Avoid overhead watering, which can promote fungal diseases. Aim for about 1 inch of water per week.
2. Fertilize as Needed: Kohlrabi is a heavy feeder. Side-dress the plants with compost or a balanced fertilizer every 2-3 weeks.
3. Weed Regularly: Keep the garden bed free of weeds, which can compete with the kohlrabi plants for nutrients and water. Hand-pull weeds carefully to avoid disturbing the roots.
4. Protect from Pests: Kohlrabi can be susceptible to pests such as cabbage worms, aphids, and flea beetles. Inspect your plants regularly for signs of infestation.
* 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.
5. Monitor for Diseases: Kohlrabi can be affected by diseases such as clubroot and black rot. Choose disease-resistant varieties and practice crop rotation to prevent these problems. Ensure good air circulation around the plants.
Phase 4: Harvesting Your Kohlrabi
The moment you’ve been waiting for! Kohlrabi is typically ready to harvest 45-60 days after planting, depending on the variety.
1. Harvest at the Right Size: Harvest the bulbs when they are about 2-3 inches in diameter. Larger bulbs can become tough and woody.
2. Harvesting Technique: Use a sharp knife to cut the bulb from the stem just above the soil line.
3. Remove the Leaves: Remove the leaves from the bulb. The leaves are also edible and can be cooked like collard greens.
4. Store Properly: Store the kohlrabi bulbs in the refrigerator for up to several weeks.
Troubleshooting Common Kohlrabi Problems
Even with the best care, you might encounter a few challenges. Here’s how to address them:
* Bulbs Splitting: This is usually caused by inconsistent watering. Ensure consistent moisture levels, especially during hot, dry periods.
* Tough or Woody Bulbs: This can be due to harvesting too late or growing conditions that are too hot or dry. Harvest the bulbs when they are young and tender, and provide consistent moisture.
* Pest Infestations: As mentioned earlier, monitor your plants regularly for pests and take appropriate action.
* Disease Problems: Choose disease-resistant varieties and practice crop rotation to prevent disease problems.
Enjoying Your Harvest
Now for the best part: enjoying the fruits (or rather, bulbs!) of your labor. Here are a few ideas:
* Raw
