Phalaenopsis Bud Blast: Identifying Environmental Triggers

Bud Wilt and Drop: Common Culprits

Healthy leaves but wilting buds on a 9-month spike suggest environmental stress during bud maturation.

Checklist: Did Any of These Occur?

• Temps below 55°F (13°C)?
• Sudden >10°F change?
• Ripening fruit nearby (ethylene)?
• Strong cleaning chemicals/paint fumes?
• Heater/AC draft on plant?

If None Apply

Provide details: exact location, light hours, watering method, fertilizer, day/night temps, humidity. Bud blast often traces to a single overlooked factor.

General Prevention

• Stable 65–75°F, >50% humidity.
• No fruit in same room.
• Morning watering; media barely moist between.
• Weak balanced fertilizer.
