Why save your own seed: heirlooms and hybrids

In short

  • Save seed only from open-pollinated varieties: heirloom, local and well-adapted ones. Seed from hybrids (F1) does not give the same plant.
  • The easiest start is beans, peas, tomatoes, lettuce and peppers: they are self-pollinating and annual.
  • Squash, cucumbers, cabbage, carrots, onions and maize cross with other varieties. They need distance or hand pollination.
  • Take seed from several plants, not one. Otherwise the variety weakens within a few years.
  • Choose the best plants all season, not just the finest fruit in August. That way the variety suits your holding better year after year.
  • Your own seed doesn't mean you never buy again. Hybrids and certified seed have their place in the garden.
