When the growing season is over, harvest your seeds and return a portion of them to the library, to help keep the seed library self-sustaining. Donations are accepted at any library location.
Only open-pollinated heirloom (non-hybrid, non-GMO) pesticide-free seeds, which are less then 4 years old are accepted. Seeds should be clean and labelled with the seed type, year grown, and the location where it was grown.
Important note: Do not save seeds from plants grown from hybrid seeds. Seeds from these plants will not produce plants like the parent plant, and will not grow true-to-type.
