What's eating my peperomia emarginella?

Peperomia emarginella is a delicate, small-leaved trailing species. Mealybugs and spider mites are the primary pest threats, particularly in warm, dry indoor conditions. Its tiny leaves make early detection harder than on larger peperomias. Fungus gnats can become an issue if the consistently moist conditions this species prefers tip into waterlogging.

White cottony specks at stem joints along trailing stems; weakened growth and leaf drop Spot-treat with isopropyl alcohol on a cotton swab; apply dilute neem oil spray weekly; remove and bin heavily infested stems

Tiny pale stipples across small leaves; webbing between stems in hot, dry air Raise humidity by grouping plants; rinse with water; apply insecticidal soap every 5–7 days for three to four treatments

Root damage from larvae; this humidity-loving species can be over-misted, creating ideal gnat conditions Ensure pots have drainage; use sticky traps; apply Bti biological drench to the compost
