Why do flowers fall off?
Firstly, not all flower drop is a concern - for example, in the gourd family (cucumber, ridge gourd, etc.), male flowers naturally drop off from the plants after few days - once their primary purpose of pollinating the female flowers is complete. Having said that, a healthy blossom that drops off suddenly should be a cause of concern.
It turns out that multiple factors often working together are responsible for this. Listed below are few of the major causes of Flower drop:
Lack or excess of sunlight exposure results in the poor setting of fruits.
Heavy Fruit Set
Insect Damage and Diseases
Improper Pollination or Lack of Pollination
Tips to Control Flower Drop

- Regularly water the plants in the right quantity depending on the climatic conditions. The growth medium should always be kept moist.
