Plant kohlrabi in early spring or late summer. Ensure well-drained soil and full sun for optimal growth.
Kohlrabi, a unique and nutritious vegetable, thrives in cool weather. It belongs to the cabbage family and features a swollen stem that can be eaten raw or cooked. Preparing the soil with compost enriches it, ensuring the plant receives essential nutrients.
Space the seeds about 6 inches apart to allow ample room for growth. Regular watering keeps the soil moist but not waterlogged. Harvest kohlrabi when the bulbs reach 2-3 inches in diameter for the best flavor. With proper care, kohlrabi can be a rewarding addition to your garden, offering both culinary versatility and health benefits.
Choosing The Right Variety
Choosing the right variety of kohlrabi ensures a bountiful harvest. Different types grow well in various climates and soils. Knowing your options helps you make an informed decision.
Popular Kohlrabi Types
Many kohlrabi varieties are available, each with unique features. Here are some popular ones:
- Early White Vienna: Known for its light green skin and tender texture.
- Purple Vienna: Features a vibrant purple color and sweet flavor.
- Superschmelz: A giant variety, perfect for those who love large bulbs.
- Grand Duke: Fast-growing and disease-resistant, ideal for beginners.
Heirloom Vs. Hybrid
Understanding the difference between heirloom and hybrid varieties is crucial. Heirloom kohlrabi types are open-pollinated and have been passed down for generations. They usually offer unique flavors and excellent adaptability.
| Heirloom | Hybrid | |
|---|---|---|
| Flavor | Rich and unique | Consistent and reliable |
| Adaptability | Highly adaptable to local climates | More uniform growth |
| Seed Saving | Easy to save seeds | Seeds may not be true to type |
Hybrid kohlrabi types are bred for specific traits. These traits include disease resistance and uniform growth. They often produce higher yields.
Both types have their advantages. Choose based on your needs and preferences.
Preparing The Soil
To grow healthy kohlrabi, preparing the soil is crucial. Proper soil preparation ensures your plants get the nutrients they need. Follow these steps to create the perfect growing environment for your kohlrabi.
Soil Requirements
Kohlrabi grows best in well-drained, fertile soil. Ensure the soil is loose and rich in organic matter. Sandy loam soils are ideal for kohlrabi. They provide good drainage and root growth.
Heavy clay soils should be avoided. They retain too much water, which can harm the plants. If you have clay soil, improve it by adding sand and compost.
Ph Levels
The ideal pH level for kohlrabi is between 6.0 and 7.5. Use a soil pH test kit to check your soil’s pH level. If the soil is too acidic (below 6.0), add lime to raise the pH. If the soil is too alkaline (above 7.5), add sulfur to lower the pH.
Maintaining the correct pH level is important. It helps kohlrabi plants absorb nutrients effectively.
Adding Organic Matter
Adding organic matter improves soil structure and fertility. Organic matter includes compost, aged manure, and leaf mold. These materials provide essential nutrients for your kohlrabi plants.
Work the organic matter into the top 6-8 inches of soil. This ensures the nutrients are readily available to the plant roots. A good rule of thumb is to add 2-3 inches of organic matter to your garden bed.
| Material | Benefits |
|---|---|
| Compost | Improves soil structure and adds nutrients |
| Aged Manure | Rich in nitrogen and other nutrients |
| Leaf Mold | Enhances soil moisture retention |
Creating the right soil conditions is essential for growing kohlrabi. By following these steps, you’ll set your plants up for success.
Planting Kohlrabi Seeds
Growing kohlrabi is simple and rewarding. Start with planting the seeds right. Follow these steps to ensure your plants thrive.
When To Plant
Plant kohlrabi seeds in early spring or late summer. Kohlrabi likes cool weather. Avoid planting during hot months. The best temperature is between 60°F and 75°F.
Seed Spacing
Proper seed spacing is crucial for healthy growth. Use this table for guidance:
| Spacing | Details |
|---|---|
| Between Seeds | 4 inches apart |
| Between Rows | 12 inches apart |
Thin seedlings if they are too close. Crowded plants will not grow well.
Germination Tips
- Plant seeds 1/4 to 1/2 inch deep.
- Keep soil moist but not waterlogged.
- Expect germination in 5 to 10 days.
- Use well-draining soil.
- Cover seeds lightly with soil.
Ensure good air circulation around seedlings. This prevents diseases.

Watering And Fertilizing
Proper watering and fertilizing are essential for growing healthy kohlrabi. These steps ensure the plant gets the right nutrients and hydration. Follow this guide to help your kohlrabi thrive.
Optimal Watering Schedule
Kohlrabi needs consistent moisture to grow well. Watering should be regular, but not excessive. Here is a simple watering schedule:
- Water your kohlrabi plants 2-3 times per week.
- Ensure the soil remains moist, but not waterlogged.
- In hot weather, water more frequently to prevent drying out.
Best Fertilizers
Using the right fertilizer can boost kohlrabi growth. Choose a balanced fertilizer for best results.
| Type of Fertilizer | Benefits |
|---|---|
| Compost | Improves soil structure and adds organic matter. |
| Liquid Seaweed | Provides essential trace elements and boosts growth. |
| Fish Emulsion | Rich in nitrogen, promoting leafy growth. |
Apply the fertilizer every 4-6 weeks for optimal growth.
Avoiding Overfeeding
Overfeeding can harm your kohlrabi. Too much fertilizer leads to nutrient burn.
- Use fertilizer sparingly and follow the instructions.
- Observe your plants for signs of overfeeding, such as yellow leaves.
- Reduce fertilizer application if you notice any signs of overfeeding.
Balanced care ensures your kohlrabi stays healthy and strong.
Managing Pests And Diseases
Growing kohlrabi can be very rewarding, but pests and diseases can pose challenges. Understanding how to manage these issues is vital for a healthy harvest. This section will guide you through common pests, disease prevention, and organic solutions.
Common Pests
Kohlrabi is often targeted by several pests. Aphids, cabbage worms, and flea beetles are the most common. These pests can damage leaves and stunt growth.
- Aphids: Small, green insects that suck sap from leaves.
- Cabbage Worms: Green caterpillars that chew holes in leaves.
- Flea Beetles: Tiny, black beetles that create small, round holes.
Disease Prevention
Keeping your kohlrabi plants healthy is essential for disease prevention. Good air circulation and proper spacing can help. Avoid watering leaves to reduce moisture, which attracts diseases. Rotate crops annually to prevent soil-borne diseases.
| Disease | Prevention Tips |
|---|---|
| Powdery Mildew | Ensure good airflow and avoid overcrowding. |
| Black Rot | Use disease-free seeds and rotate crops yearly. |
| Clubroot | Test soil pH and keep it above 7.2. |
Organic Solutions
Organic methods are effective for managing pests and diseases. Use neem oil or insecticidal soap to control aphids. Handpick cabbage worms and use floating row covers for flea beetles. Crop rotation and compost improve soil health and reduce disease risk.
- Spray neem oil for aphids.
- Handpick cabbage worms.
- Use row covers for flea beetles.
- Rotate crops yearly.
- Amend soil with compost.
Thinning And Transplanting
Thinning and transplanting are crucial steps in growing kohlrabi. These processes ensure your plants have enough space and nutrients to grow strong and healthy. Proper thinning and transplanting can help you achieve a bountiful harvest.
When To Thin
Thinning should occur when the kohlrabi seedlings are about 2-3 inches tall. This is the right time to make sure each plant has enough room to grow. Using clean, sharp scissors, cut the weaker seedlings at the soil line. This will allow the stronger seedlings to thrive.
How To Transplant
Transplanting should be done when kohlrabi seedlings have developed their first set of true leaves. Follow these steps for successful transplanting:
- Water the seedlings well before transplanting.
- Prepare the new planting area with rich, well-drained soil.
- Gently lift the seedlings from their original location.
- Place each seedling in a hole, keeping the soil level the same.
- Firm the soil around the base of the seedlings.
- Water the transplanted seedlings thoroughly.
Maintaining Plant Health
After thinning and transplanting, keeping your kohlrabi plants healthy is key. Here are some tips:
- Watering: Water the plants regularly, ensuring the soil remains moist.
- Weeding: Remove weeds that compete for nutrients and water.
- Fertilizing: Use a balanced fertilizer to promote growth.
- Pest Control: Monitor for pests and use organic methods to control them.
By following these steps, your kohlrabi plants will grow healthy and strong. This will lead to a successful and rewarding harvest.
