Cucumbers turning yellow and dropping off? Watering and fertilising errors are to blame

Yellowing and dropping cucumbers in home gardens are most commonly caused by inconsistent watering — either too much or too little — combined with improper fertilisation. A gardening expert explained that cucumbers need regular, moderate watering and a balanced supply of nutrients. Large fluctuations in soil moisture cause plant stress, which leads directly to the yellowing and shedding of fruit.
