This article will inform you of the potential causes of cucumber holes as well as the steps you can take to safeguard your cucumber plant from harmful pests.

What Causes Holes in Cucumbers?

Drought Conditions (Lack of watering)

Inadequate pollination, pests, insects, and poor irrigation can all result in holes.

When there is a drought, the cucumber plant grows slowly; but, when water is supplied later, as when it rains, the cucumber plant absorbs a lot of water and grows quickly.

This is also common among home gardeners who for whatever reason neglect to water their plants for a while. When water is finally applied, the plants are so thirsty that it takes a long time for them to absorb it, which causes a growth surge.


If the plant has gone without water for a while, do not apply a lot of water. Apply little quantities every time you water until you are using the normal quantity of water again.

These development spurts are what create the gaps or empty areas inside the fruit.
