Answer: It sounds like a pollination problem. The wet spring weather, combined with reduced populations of honeybees due to parasites, may have led to little or no pollinator activity in your garden. Encourage pollinators by planting a variety of flowers in and around your garden. In the meantime, try hand pollinating the squash blossoms by using a small artists' paintbrush to transfer pollen from a male flower to a female one. Hopefully, the weather will be more agreeable for pollinators in the future.
