Why Are My Plant Flowers Falling Off?
Flower drop can happen before fruit set for several different reasons. The best clue is what happened around flowering — temperature swings, water stress, flower damage, pollination conditions, or a plant that is already struggling.
What this symptom means
Fallen flowers are the endpoint. To diagnose the cause, inspect remaining flowers and the whole plant, then follow the crop-specific owner that matches the timing and associated clues.
What to notice first
- Healthy flowers dropping versus visibly damaged blossoms
- Recent heat, cold, wind, or abrupt watering changes
- Whether fruit starts to form before the flower drops
- Leaf wilt, root stress, pests, or weak new growth
