no squash fruit
Well-growing squash of several types with many male flowers, but no female flowers, therefore no vegetables. Several plants of each species planted together in hills. Soil tested by AG extension at the beginning of the season. We have large healthy foliage and long runners with plenty of male blossoms. Very few female blossoms. Soil is good, tested well, and we added some general fertilizer as we turned the soil. This is the second year this has happened.
This could be pollination problems.
Do you see bees in the garden?
Hand pollinated may be worth a try.
Try a dose of Bone Meal to increase the Phosphorous level just a bit to try to increase flowering.
