Rose Buds Falling Off En Masse: Causes and June Drop

Why 100+ Unopened Buds Dropped Suddenly

Healthy rose dropped ~100 unopened buds overnight.

Possible Causes

• Beetles/animals biting buds off
• Insect eggs in bud base (pin hole visible) → larvae destroy bud
• Sudden heat wave → physiological drop
• June drop: Natural self-thinning when plant can't support all buds (common in fruit trees, occurs in roses too)

Diagnosis

Check bud bases for pin holes. Open buds for tiny worms. Note recent weather. If none apply, it's likely natural June drop.
