So You want to Go To Seed?
Start with easy crops such as peas, beans and tomatoes, and herbs like coriander and dill.
Plant a single variety to help ensure the seeds you get are pure-bred.
Stagger crop planting of the same species to avoid cross-pollination e.g. cabbage and cauliflower.
Wait until seeds are fully mature before harvesting.
Save seeds from several plants of each species to maintain good genetic diversity.
Wet-fruited veg (e.g. cucumber and squash) are eaten when still immature, so you need to allow a few to remain on the plant to fully mature, then remove and dry the seeds.
Dry-fruited veg (e.g. beans, peas, spinach and brassica) can be harvested when the pods and seeds are brown and dry.
Seeds must be completely dry before storing in sterilised jars in a cool, dark, dry place. Label and date them clearly.
Share your seeds with fellow gardeners and encourage them to do the same.
