Leathery Phalaenopsis Leaves: Tetraploid Trait

Leathery Leaves on Phalaenopsis: Genetic Trait

Jinny's Phalaenopsis (2 weeks old, full bloom) has two bottom leaves becoming leathery. Not repotted (blooming). Past 4 days in humidity tray, full direct sun (2 inches from window). Original plastic pot, drainage bottom, added side holes. Asks about leathery leaves.

Expert Response

Jinny, leathery leaves likely genetic—could indicate tetraploid. If flowers large with heavy substance, another tetraploid sign. Usually good. Move plant further from window. Phalaenopsis like direct morning sun (less intense). You're doing right things. When flowering ends, could repot, though mix looks fresh in photo.
