Cucumbers generally prefer warm and sunny conditions for optimal growth, and they are sensitive to cold temperatures and excessive rainfall.
While cucumbers can tolerate some cooler weather, especially if they are well-established plants, a cold and rainy summer may pose some challenges for their growth and productivity.
Here's what you need to know.
Temperature Tolerance
Cucumbers are warm-season vegetables that thrive in temperatures between 70°F and 95°F.
They can tolerate cooler temperatures, especially during the early stages of growth, but prolonged exposure to cold and chilly conditions can slow down their growth and affect their overall health.
Rainfall
Excessive rainfall can lead to several issues for cucumber plants.
First, waterlogged soil can suffocate the roots and lead to root rot.
This can stunt the growth of the plant and even cause it to die.
Second, heavy rain can cause flowers to drop prematurely, which can impact fruit production.
Additionally, rain can lead to the spread of fungal diseases, which cucumbers are susceptible to, especially when their foliage remains wet for extended periods.
Sunlight
While cucumbers need plenty of sunlight for photosynthesis and growth, cold and rainy conditions can reduce the amount of sunlight reaching the plants.
This can result in slower growth and less vigorous plants.
