Seed Saving Guide #2703
Binomial name: Brassica oleracea
|Flower Type||Perfect, self-incompatible|
|Population Required for Viable Seeds||5|
|Population Required to Maintain Variety||20-50|
|When to Harvest||In the second year when seed pods (siliques) are dry and turn from green to tan. Seeds will be brown.|
|How to Harvest||
Cut stalks with seed pods over a container or drop cloth to catch any seeds that are released. Spread seed pods on a cloth and leave to dry for 7-14 days. Rub seed pods between hands to break them open and release the seeds.
|How to Clean||
Screen or winnow to remove remaining stalks and chaff. If further cleaning is needed, roll seeds down a felt-lined ramp; the chaff will stick to the felt and the clean seeds can be collected at the bottom.

What is Seed Saving?
Seed saving is the practice of collecting and storing mature seeds from open-pollinated plants. By allowing plants to reach full maturity and harvesting the seeds, they can be cleaned, dried, and stored for future use.
