Troubleshooting
Cuban Peperomia problems — and how to fix them
Cuban Peperomia (Peperomia cubensis) 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
This epiphytic species is particularly susceptible to root rot because its natural bark substrate drains almost instantly; indoor compost retains far more moisture, so err on the side of underwatering and use a very free-draining mix.
Fungus gnats
Adults are attracted to the moist compost surface; allow the top layer of compost to dry between waterings, use yellow sticky traps to monitor and capture adults, and apply a Bti-based biological control drench for persistent larval infestations.
