Bud Blast — Orchid Buds Dropping Before Opening

Commonly affects: Phalaenopsis spp. and other Orchidaceae (Orchid)

Developing flower buds turn yellow or shrivel and drop off the spike before ever opening, sometimes affecting the entire spike at once.

Potential Causes

  1. 1Sudden environmental changes — temperature swings, cold drafts, or being moved to a new location
  2. 2Low humidity causing buds to dry out and abort
  3. 3Exposure to ethylene gas from ripening fruit, cigarette smoke, or gas appliances nearby
  4. 4Underwatering during the critical bud development stage

Solution Steps

  1. 1Keep the plant in a stable location away from drafts, heating vents, and air conditioning once a spike begins developing
  2. 2Increase humidity around the plant during bud development
  3. 3Keep the plant away from ripening fruit and other ethylene sources
  4. 4Maintain consistent watering through the budding period without letting the plant dry out completely

Prevention Tip

Once a flower spike starts developing buds, avoid moving the plant or exposing it to any sudden environmental change until blooming is complete.
