1. Insufficient pollination (low bee activity)
Likelihood: HighWatermelon needs insects-especially bees-to transfer pollen from male to female blossoms. Low bee activity from poor habitat, pesticide drift, or bad weather during the bloom window is the leading cause of few or aborted fruits in home gardens.
Identification
- remove_circle_outlineFew bees visiting flowers during warm mornings; many open female blossoms with no pollen on stigmas
- remove_circle_outlineIsolated flowers with intact petals that drop without forming a small melon, often within 24-48 hours
- remove_circle_outlineMale blossoms abundant relative to female blossoms, and no visible pollen on female stigmas
- remove_circle_outlineTiming of blossom opening: female and male blooms open at different times of day and require overlap; observe for 2-3 mornings
