Compressed Peperomia problems — and how to fix them
Compressed Peperomia (Peperomia coarctata) 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.
Stem and crown rot
The densely compressed growth traps moisture against stems and at the crown, making rot the most common cause of decline. Space the plant where air can circulate around it, water strictly from the base or at pot edges rather than into the crown, and use a very gritty compost mix.
Mealybugs in leaf axils
The tight leaf clusters of compressed peperomia provide ideal sheltered conditions for mealybugs, which are often not spotted until the infestation is established. Inspect the interior of the plant monthly; treat with 70% isopropyl alcohol applied by cotton bud followed by insecticidal soap spray to the entire plant.
