Guppy's Peperomia problems — and how to fix them
Guppy's Peperomia (Peperomia guppyana) 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 and stem rot
Overwatering or slow-draining compost quickly leads to root rot; affected plants wilt despite moist soil and stems may turn soft and brown at the base. Repot into a fresh, well-draining mix and cut back watering frequency.
Mealybugs
White waxy clusters in leaf axils and on stems signal mealybug infestation; remove visible insects with a cotton bud dipped in 70 % isopropyl alcohol and apply neem oil or insecticidal soap spray weekly until clear.
