Phalaenopsis Leaf Loss: Crown Rot Emergency

Black, Soft Base = Crown Rot—Survival Unlikely

Leaves falling with blackened base indicates crown rot from degraded, waterlogged mix. Unpot, rinse roots, remove mushy ones. Repot in soaked, sifted fir-bark mix. Water sparingly, early morning. Use small fan to dry crown. Better to be too dry than too wet.
