yellow leaves on Gloxinia
Quick answer
If your Gloxinia has yellow leaves, the most likely cause is: Gloxinia's broad, velvety, downy leaves are adapted to bright but filtered light under a greenhouse bench, and when placed in direct sun the foliage is sunscalded — the upper surface of the leaf bleaches, yellows, and browns where ultraviolet intensity exceeds what the thin leaf tissue can dissipate.
Start here:
- 1. Move the plant into bright light that is filtered by a sheer curtain or into a spot that receives morning sun only, so the leaves are never lit by harsh midday rays.
- 2. Pair the move with steady warmth and a moist atmosphere, since gloxinias require a warm, moist environment during growth and blooming to recover from leaf scorch.
