Coin-Leaf Peperomia problems — and how to fix them
Coin-Leaf Peperomia (Peperomia polybotrya) 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.
Root rot from overwatering
The most common issue; succulent leaves mask dehydration, so growers overwater. Symptoms include mushy stems at the soil line and yellow, wilting leaves. Allow soil to dry more between waterings and ensure a draining pot.
Leaf edema
Blister-like bumps or corky raised patches on leaf surfaces caused by excess moisture build-up in cells due to overwatering or high humidity combined with wet soil. Reduce watering frequency to resolve.
Spider mites and mealybugs
Spider mites cause pale stippling and fine webbing; mealybugs appear as white cottony masses in leaf axils. Treat with neem oil spray or wipe mealybugs off with an alcohol-dipped cotton swab.
