100% Michigan Homestead Grown, 100% Open-Pollinated - Each & Every Seed
There are four common species of squash and you can "safely" grow one variety from each species in the same garden without worry of cross-pollination. Keep in mind, however, that squash blossoms require pollinators, so there is the chance a bee unintentionally brings pollen from a neighboring garden. To avoid this risk, hand-pollination is recommended.
The four common species of squashes: Cucurbita (C.) angyrosperma, C. maxima, C. moschata, and C. pepo.
