I planted squash plants among my flowers. They look great and are blooming, but they’re not setting any squash. The blossom falls off before the squash begins to grow. Any help?
When squash plants bloom without producing squash, it probably means they need help with pollination. Squash plants produce male flowers at first, followed by female flowers a few days later. (You can tell the difference this way: male flowers have a single stamen in the center; female flowers have a four-part pistil, and appear swollen just beneath the blossom.)
According to information at GardenGuides.com, if the female flowers drop off without growing a squash, it means that it didn’t get pollinated by the bees or other pollinators that visit the garden.
Squash flowers are big, so if the bees aren’t doing an adequate job, you can do it yourself. Use a cotton swab or a small, soft brush to gather the pollen from inside the male flower, and transfer it to the female flower. Or pick a male flower, remove the petals and swirl it around inside the female flower. (Look here for pictures of how this is done). With luck, a squash is born!
