Itsy Bitsy Peperomia problems — and how to fix them
Itsy Bitsy Peperomia (Peperomia rubella) 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.
Mealybugs in leaf clusters
The whorled clusters of four tiny leaves create tight hiding spots for mealybugs; inspect regularly and treat infestations with alcohol-dipped cotton swabs or a neem oil spray.
Cercospora leaf spot
This fungal disease produces dark brown or tan raised lesions on leaf undersides; improve air circulation, avoid wetting foliage when watering, and remove affected leaves promptly.
Stem etiolation in low light
Insufficient light causes the slender stems to stretch and lose their compact clustering habit, producing weak, sparsely-leaved vines; move to a brighter position or supplement with a grow light.
