Yellow-Spike Peperomia problems — and how to fix them
Yellow-Spike Peperomia (Peperomia xanthostachya) 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
Overwatering or poorly draining compost causes roots and stem bases to rot; symptoms include yellowing lower leaves, a mushy stem base, and wilting despite wet soil. Repot into fresh free-draining compost after removing all rotten tissue.
Mealybugs
White, waxy cottony colonies appear at leaf axils and stem joints; dab with a cotton bud dipped in 70% isopropyl alcohol, and follow up with insecticidal soap spray every 7–10 days until clear.
