Watermelon Blooms but No Fruit: Pollination Failure

Watermelons need bee pollination; each female flower opens one morning, requiring multiple bee visits.

Causes

  • Low bee populations (disease, parasites).
  • Competing flowers (weeds, ornamentals) more attractive.

Solutions

  • Hand-pollinate: transfer male pollen to female (swollen base) in early morning.
  • Plant bee-friendly flowers nearby but not overwhelming.
  • Avoid pesticides during bloom.

Location matters—bee decline is regional.
