Phalaenopsis Bud Blast: Heat Shock vs. Root Rot

Likely Cause: Temperature Shock

Newly purchased Phalaenopsis with healthy buds that suddenly droop and yellow after transport likely suffered heat stress. Vehicle temperatures above 85°F, especially with stops, cause bud abortion. Affected buds won't recover, but the plant often produces new buds in coming weeks.

Less Likely: Root Rot

Many nurseries use degraded or inappropriate mixes that cause root loss. Check roots when repotting after flowering. Soak fresh fir bark mix before use (dry bark repels water). Remove mushy roots. Repot in plastic pot with ample drainage. Water weekly thereafter.
