Phalaenopsis Losing Leaves Rapidly: Watering Errors, Temperature, and Root Check

Four Leaves in Five Months: Emergency Signal

Phalaenopsis normally lose 1-2 leaves per year. Losing four in five months with no new growth indicates serious cultural problems.

Watering Interrogation

• Watering from above? Late day/evening?
• Misting frequently?
• Black sooty areas at leaf bases? (fungus from overnight moisture)
• Any air movement?

All watering/misting must be morning-only. Air movement helps drying.

Temperature Check

Michigan cool is fine if >60°F. Below 50°F causes damage. Cool temperatures slow drying—increase watering intervals.

Root Inspection Required

Unpot to check roots. Mostly firm/healthy = repot in same-size pot. Many mushy roots = trim dead, repot in smaller pot. Position bottom leaf just above mix. Pot barely containing roots prevents waterlogging.
