Troubleshooting
Metallic Peperomia problems — and how to fix them
Metallic Peperomia (Peperomia metallica) 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.
Overwatering and root/stem rot
The most common problem. Mushy stems, yellowing or dropping leaves and a sour, waterlogged pot signal Pythium-type rot. Let the soil dry more between waterings and repot into fresh, airy mix if rot has started.
Faded or all-green leaves
Loss of the metallic sheen and red undersides usually means too little light. Move to a brighter spot with bright indirect light (not direct sun) to restore the colouring.
Cercospora leaf spot
Brown or black spots, often with a yellow halo, point to fungal leaf spot encouraged by wet foliage. Remove affected leaves, avoid overhead watering and misting, and improve airflow.
Fungus gnats
Small black flies around the soil thrive in chronically damp mix. Let the top layer dry out, use bottom-watering, and add a layer of grit or use yellow sticky traps to break the cycle.
Spider mites and mealybugs
Fine webbing, stippled leaves (mites) or white cottony tufts in leaf joints (mealybugs) appear in dry indoor air. Wipe leaves, raise humidity slightly, and treat with insecticidal soap or diluted neem.
Leaf drop from cold or drafts
Sudden leaf loss often follows exposure to temperatures below about 10°C (50°F), cold drafts, or hot radiator air. Keep it in a stable 18-24°C spot away from doors, vents and heat sources.

Why is my metallic peperomia overwatering and root/stem rot?
The most common problem. Mushy stems, yellowing or dropping leaves and a sour, waterlogged pot signal Pythium-type rot. Let the soil dry more between waterings and repot into fresh, airy mix if rot has started.
Why is my metallic peperomia faded or all-green leaves?
