If your cucumber fruits (yes, botanically speaking, cucumbers are fruits, not vegetables) are not fully formed or have an end that's nothing more than a tiny nub, poor pollination is likely to blame. Each flower must be visited by a pollinator many, many times in order for the fruit to fully form.

Full Answer

Why do my cucumbers have little cucumber leaves?

Why do cucumbers turn yellow before maturity?

A: In my experience, cucumbers that turn yellow before maturity are not getting full pollination. The process of elongating and increasing diameter of the fruit is triggered by hormones released by seeds as they grow. If the immature seed are not pollinated, hormones are lacking, leading to irregular growth and color.

What are the most common cucumber planting mistakes?

How to grow cucumbers?

Growing Cucumbers: For good cucumber production, make sure your crops gets 1 inch of water every week– that is a deep soaking. The critical watering period for cucumbers is during flowering and fruit development. Insufficient watering can result in small fruit. Cucumbers are heavy feeders so apply aged compost to the garden in spring and again in fall; give cucumbers a side-dressing of compost tea every 2 weeks during the growing season. Feeding and watering are very important when blossoms are setting, Small fruit can also be the result of insufficient pollination. Standard cucumbers produce male flowers first, then female–female flowers have a tiny cucumber at the base. If the fruit does not develop then the problem is lack of pollination. Insects usually take care of pollination, but you can improve pollination by hand-pollinating–gather pollen from the male flower with a swab and dab the female flower.

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.
