Miquel's Peperomia problems — and how to fix them
Miquel's Peperomia (Peperomia miqueliana) 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
Caused by overwatering or compost that drains too slowly; the stem base becomes soft and dark. Remove the plant from its pot, cut away rotten roots, treat cut surfaces with cinnamon powder or activated charcoal, and repot into fresh free-draining compost.
Scale insects
Brown, waxy shell-like bumps appear on stems and the undersides of leaves, weakening the plant by sap-sucking; scrape off manually with a soft toothbrush, then apply neem oil or horticultural mineral oil spray at weekly intervals.
