Isolation may not be necessary if generic seeds (rather than a specific variety) are desired. Pollen is very fine so isolation netting is often ineffective, but risk of cross-pollination is low as most home gardeners remove plants once they have bolted.
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.
