Aphid Infestation

Aphids are common pests for Phalaenopsis that secrete 'honeydew,' a sticky, sugary substance. They congregate on the undersides of leaves and new growth to suck sap from the orchid's vascular system.

Very Common

Very Common

Sooty Mold

This is not a primary cause but a secondary symptom; black, fuzzy mold grows on top of the sticky honeydew left by pests. This fungus can block photosynthesis in your Phalaenopsis leaves.

Common
