The Q&A Archives: yellow squash problems

Question: the six plants get plenty of sun and are continuously blooming, but no fruit forms. the blossoms just fall off. What do they need?

Answer: Squash plants develop both male and female flowers and insects must visit each flower to transfer the pollen from the male to the female. If the flowers are not being pollinated it's because there's little to no insect activity in your garden (sometimes the result of repeated insecticide sprays - sometimes because of cool temperatures). You can identify the male and female flowers then remove a male flower and brush the insides of it to the insides of a female flower. This should start the process rolling and you'll have squash. Male flowers are attached by a straight slender stem; female flowers have a slight swelling directly behind the flower petals. These swellings will develop into squash if the flower is pollinated.

Best wishes with your garden!
