Large-Leaf Peperomia problems — and how to fix them
Large-Leaf Peperomia (Peperomia grandifolia) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from overwatering
Soggy compost causes the shallow roots to rot quickly; the plant wilts and lower stems may turn mushy. Allow the top half of the compost to dry between waterings and ensure the pot has drainage holes.
Fungus gnats
Consistently damp compost attracts fungus gnat larvae, which damage roots. Let the surface dry out between waterings and, if infestation persists, use a biological nematode drench (Steinernema feltiae).
