I have received many questions through the years if cross-pollination
will occur with plants in the cucurbit family including cucumber, squash, watermelon, pumpkin and gourds. Cucurbits
have separate male and female flowers on its vines requiring bees for pollination which can increase the possibility of cross-pollination.
Although these garden plants are in the same family (cucurbit) they are not all in the species which is generally required for cross-pollination
with the exception of squash that will cross some other species
Cucumbers and watermelons will not cross with each other or other cucurbit species.
Squash, pumpkins and gourds of the same species will cross-pollinate that can result in unique and oddly shaped fruits without adequate planting distance between these. Bees
are active early in the day through mid to late morning so any insect control
measures should be done in the afternoon to insure good pollination. Keith Collins
