You can get seeds from plants by harvesting them once they are ripe and the seedheads have dried. Here's a breakdown of the process:
Steps to Collecting Seeds
-
Timing is Key: Collect seeds on a dry day as soon as the seedheads (such as capsules or pods) have ripened. This prevents mold and ensures the seeds are mature.
-
Harvest the Seedheads: Pick the seedheads, either individually or on stalks.
-
Drying the Seedheads: Lay the collected seedheads out to dry in a well-ventilated area. Good options include a greenhouse bench, a warm windowsill, or an airing cupboard. The goal is to allow the seedheads to fully dry out, which will help release the seeds.
-
Seed Extraction:
- Natural Release: Some seedheads will open naturally when dry, releasing the seeds.
- Manual Release: If the seedheads don't open on their own, gently crush the pods and capsules to release the seeds. You can use your hands or a light tool.
-
Cleaning the Seeds: After extraction, you may need to clean the seeds to remove any remaining plant debris. This can involve using a sieve or gently blowing away the chaff.
Tips for Success
- Proper Drying: Ensuring the seedheads are thoroughly dry is crucial for preventing mold growth and ensuring the seeds are viable for future planting.
- Gentle Handling: Be gentle when extracting the seeds to avoid damaging them.
- Storage: Store the cleaned and dried seeds in a cool, dark, and dry place, such as an airtight container or paper envelope, until you're ready to plant them. RHS Seed Collecting offers further guidance on seed storage.
By following these steps, you can successfully collect seeds from your plants and enjoy them for future gardening endeavors.
