Window Plant problems — and how to fix them
Window Plant (Fenestaria rhopalophylla) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Overwatering and rot
The leaf tips turn transparent and mushy when waterlogged. Remove rotted leaves, cease watering, and allow the soil to dry for several weeks before resuming. The plant can survive extreme drought but cannot tolerate sustained wet conditions.
Etiolation in low light
In insufficient light, leaves elongate upward and lose their characteristic stubby, windowed form. The plant becomes susceptible to rot as the lengthened tissue cannot support itself. Reposition to maximum sunlight as soon as etiolation is noticed.
Fungus gnats
Larvae thrive in moist, organically rich compost. Use a very gritty, low-organic mix and allow it to dry fully between waterings to eliminate the damp conditions gnats prefer. A layer of coarse sand on the surface also deters egg-laying.
Prevent window plant problems before they start
Most window plant issues are care-mismatch, not bad luck. Dial in the basics:
