How do cucumbers produce flowers?
Most standard cucumbers produce male flowers first; the female flowers follow a few days later. The cucumber plant is dependent upon insects to visit the male and female flowers for full pollination. When female flowers–the ones with the tiny cucumber at the base of the flower–do not fully develop, the problem is lack of pollination. If the weather has been cool or cloudy or rainy, insects have likely not been active in your garden. You can wait for the weather to get better and the insects to get busy, or you can improve pollination by hand-pollinating. You can hand-pollinate by picking off the male flower, pull off the petals, and directly rub the pollen on the stigma of the female flower. Now, one more thing: there are cucumber varieties that are gyonecious–meaning they produce female flowers only. (Seed suppliers usually specify if a cucumber is gynoecious–so double check your variety.) Gynoecious cucumber varieties require a second variety (one that produces male flowers) to be planted nearby. If no male is planted close by the gynoecious cucumber–the female flower will not be pollinated.
