Saving seeds from your kohlrabi plants is a rewarding way to ensure you have new plants for the next growing season. It allows you to maintain the genetic traits of your favorite varieties and save money on buying new seeds each year. This guide will walk you through the simple steps to harvest, dry, and store kohlrabi seeds effectively.
Understanding When to Harvest Kohlrabi Seeds
Kohlrabi plants are biennials, meaning they take two years to complete their life cycle. To harvest seeds, you need to allow the plant to grow through its second year. The seeds are ready when the seed pods turn brown and start to dry out, typically in late summer or early fall.
Steps to Harvest the Seeds
- Identify mature seed pods on your kohlrabi plant. They will be brown, dry, and brittle.
- Use scissors or garden shears to carefully cut the seed pods from the plant.
- Place the seed pods in a paper bag or a breathable container.
- Allow the pods to dry in a warm, dry place for about 2-3 weeks.
- Once fully dried, gently crush the pods to release the seeds.
Cleaning and Storing Seeds
After extracting the seeds, remove any plant debris or chaff. Rinse the seeds lightly with water if needed, then spread them out on a paper towel or screen to dry completely. Store the seeds in an airtight container, such as a glass jar or seed packet, in a cool, dark, and dry location. Proper storage can keep your seeds viable for 2-3 years.
Tips for Successful Seed Saving
- Choose healthy, disease-free plants for seed collection.
- Label your seed containers with the variety and date.
- Keep seeds dry and avoid exposure to direct sunlight.
- Consider isolating different varieties to prevent cross-pollination.
By following these steps, you can enjoy the satisfaction of growing your own kohlrabi from saved seeds year after year. Happy gardening!
