Bud Blast Draft Damage on orchid
What's Happening
Drafts from windows, doors, or HVAC systems create localized microclimate fluctuations that orchid flower buds cannot tolerate. While the ambient room temperature may read 72°F, drafts can drop bud-level temperatures to 55-60°F intermittently. These rapid micro-fluctuations desiccate the delicate column tissue connecting bud to stem, triggering abscission as a defense mechanism.
How to Fix It
- 1
Relocate plant immediately to draft-free zone—test by holding a lit candle near the location; flickering indicates problematic air movement
- 2
If buds are still firm and green, stabilize environment immediately to prevent further loss
- 3
Remove dropped buds to prevent fungal growth on the spike
- 4
Apply cinnamon powder to cut spike tips to prevent infection entry
- 5
Do not move plant again for 4+ weeks
How to Prevent It
Position orchids 3-5 feet from windows and exterior doors. Use draft stoppers on door bottoms. Redirect HVAC vents away from plant locations with deflectors. Monitor with thermometer at plant level.
