Harvesting Broccoli Seeds
Since broccoli is not self-pollinated but is cross-pollinated by insects, you’ll need at least 3 plants, placed close together, for a good set. It will cross with other brassicas such as brussels sprouts, cabbage, cauliflower, kale, and kohlrabi, so you should either raise only one of these each year or keep them well separated. When the seedpods are thoroughly dry on the plant. Cut the entire plant to the ground and hang it in a dry well-aerated spot indoors for a seek or two. When the seeds are dry, remove them from the pods by placing the pods in a bag and crushing them with a rolling pin or your hands. Winnow the seeds and store. If you live in cold climates and want to harvest seeds, you will need to start broccoli indoors in the spring. It is a cool weather crop and it will withstand temps as low as 25 degrees. Seeds are harvested ANNUALLY.
