Phalaenopsis Cold Draft Damage: Flower Loss and Repotting Guide

Cold Draft Impact

Attic fan + open window = sudden cold blast. Flowers wilt/buds blast (ethylene sensitivity). Leaves likely okay. Plant will recover.

Immediate Care

• Remove wilted flowers/spikes.
• Move to stable, warm location (65–80°F).
• No repotting until after bloom cycle ends.

Annual Repotting Procedure (Post-Bloom)

1. Soak fresh bark 1 hour; drain.
2. Unpot, rinse all old mix off roots.
3. Trim mushy roots.
4. Pot in plastic container (fits roots snugly) with damp bark.
5. Tap to settle; base of leaves at mix surface.
6. No water 1 week; then resume normal care.

Why Special Mix?

Orchids are epiphytes—roots need air. Coarse bark mimics natural conditions. Repot yearly as mix breaks down.
