Phalaenopsis Orchid brown spots

A dry tan patch facing suddenly stronger sun may be scorch. A wet-looking lesion that enlarges or reaches the leaf base needs prompt attention.

Dry, stable injury

Move to bright indirect light and retain the green part of the leaf. A bruise can also brown after handling, so compare with recent transport or cleaning.

Soft, enlarging damage

Separate the orchid, keep the crown and leaves dry, and photograph the lesion and roots. Contact a local extension or plant diagnostic service if it spreads rapidly or involves the crown. Clean tools between cuts and plants; avoid splashing from an affected orchid onto others.
