Kohlrabi, with its unique bulbous stem and delicate flavor, is a welcome addition to any vegetable garden. But starting kohlrabi indoors gives you a head start on the growing season, ensuring a bountiful harvest even in cooler climates. This comprehensive guide will walk you through the process of planting kohlrabi seed indoors, from seed selection to transplanting, so you can enjoy fresh, homegrown kohlrabi in no time.
Selecting the Right Seeds and Starting Time
The first step to successful indoor kohlrabi cultivation is choosing the right seeds. Look for high-quality seeds from a reputable source, ensuring they are labeled for indoor planting. Consider the variety you want to grow, as some are better suited for specific climates and have different maturity times.
The ideal time to start kohlrabi seeds indoors is 4-6 weeks before the last frost date in your area. This allows the seedlings to develop a strong root system before being transplanted outdoors.
Preparing Your Seed Starting Mix and Containers
Kohlrabi seedlings need a well-draining, nutrient-rich soil mix. You can use a commercial seed starting mix or create your own using a blend of peat moss, vermiculite, and perlite.
Choose small, individual seed starting pots or trays with drainage holes. These containers allow for optimal root development and prevent overwatering.
Planting the Seeds: A Step-by-Step Guide
1. Fill the containers: Fill the pots or trays with your seed starting mix, leaving about ½ inch of space at the top. Gently dampen the mix with water.
2. Sow the seeds: Make a shallow hole, about ¼ inch deep, in the center of each pot or cell. Place one seed in each hole and cover it with soil.
3. Gently water: Mist the soil with a watering can or spray bottle to ensure the seeds are well-hydrated but not waterlogged.
4. Cover and label: Cover the containers with a clear plastic dome or plastic wrap to create a humid environment. Label each container with the variety of kohlrabi and the planting date.
Providing Optimal Conditions for Germination
Kohlrabi seeds need warmth and consistent moisture to germinate. Place the containers in a warm, sunny location, ideally with temperatures between 70-75 degrees Fahrenheit. Direct sunlight can be too intense, so consider using a grow light or placing the containers near a south-facing window.
Check the soil moisture regularly and water as needed, keeping the soil consistently moist but not soggy.
Thinning and Transplanting
Once the seedlings have developed two true leaves, it’s time to thin them. This allows the remaining seedlings to grow stronger. Choose the healthiest seedling in each pot or cell and remove the others.
When the seedlings are 4-6 weeks old and have several true leaves, they are ready to be transplanted outdoors. Choose a sunny location with well-drained soil. Dig a hole slightly larger than the root ball and gently ease the seedling out of its container, being careful not to disturb the roots. Plant the seedling at the same depth it was growing in the container. Water well after transplanting.
Caring for Your Kohlrabi Plants
Kohlrabi plants need consistent watering, especially during hot, dry periods. Water deeply and thoroughly, allowing the soil to dry slightly between waterings.
Fertilize your kohlrabi plants every two weeks with a balanced liquid fertilizer. This will help them grow strong and produce healthy bulbs.
Harvesting Your Delicious Kohlrabi
Kohlrabi is ready for harvest when the bulbs are about 2-3 inches in diameter. The bulbs should feel firm and smooth. To harvest, use a sharp knife to cut the bulb off at the base of the stem.
Enjoying Your Kohlrabi Harvest
Kohlrabi is a versatile vegetable that can be eaten raw, steamed, roasted, or sautéed. It has a mild, slightly sweet flavor that pairs well with many other ingredients.
Final Thoughts: From Seed to Supper
Planting kohlrabi seed indoors is a rewarding experience that allows you to enjoy fresh, homegrown produce earlier in the season. By following these simple steps, you can ensure your kohlrabi plants thrive and produce delicious bulbs for you to enjoy.
