Rhombus-Leaf Peperomia problems — and how to fix them
Rhombus-Leaf Peperomia (Peperomia rhombea) 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
Waterlogged compost destroys the fine, shallow roots of this semi-succulent; the plant wilts despite wet soil and the stem base may become soft and discoloured. Always check the compost before watering and ensure the pot has drainage holes.
Mealybugs in leaf axils
The compact, sheltered axils where the rhombic leaves meet the stem make attractive hiding places for mealybugs; check regularly for white cottony clusters and treat promptly with cotton buds dipped in isopropyl alcohol followed by a neem oil spray.
