Why does your Phalaenopsis Andorra have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyExcessive moisture or poor drainage in the orchid bark causes roots to suffocate and decay. When roots die, the Phalaenopsis cannot transport water to the leaves, triggering a stress response that results in rapid leaf drop.
Phalaenopsis orchids are tropical plants sensitive to sudden shifts in ambient temperature. Exposure to cold drafts (below 13°C/55°F) or extreme heat can cause the plant to shed leaves to conserve energy.
If the medium dries out completely for extended periods, the orchid's pseudobulbs and leaves lose turgor pressure. To prevent total systemic collapse, the plant may shed older leaves to reduce transpiration.
Bacteria can enter through wounds or water trapped in the leaf crown. As the infection spreads through the vascular tissue, the leaves lose structural integrity and drop prematurely.
