What's eating my peperomia clusiifolia?

Peperomia clusiifolia (Red Edge Peperomia) is most commonly troubled by mealybugs, which colonise the thick leaf axils and stem joints. Spider mites appear in dry centrally heated rooms. This robust species resists pests well when kept in good health; inspect monthly and act at the first sign of infestation.

White waxy clusters in leaf axils and at stem nodes; sticky honeydew and possible sooty mould Dab with isopropyl alcohol on a cotton swab; treat whole plant with neem oil spray weekly for four weeks; isolate from other plants

Fine pale stippling on the succulent-like leaves; webbing visible on undersides in dry air Wipe leaves with a damp cloth, raise humidity, and apply insecticidal soap or dilute neem oil every 5–7 days

Brown oval shells adhered to stems and leaf undersides; leaves yellow and plant loses vigour Scrape off scale with a soft toothbrush; apply horticultural oil spray to smother remaining crawlers; repeat after 10 days
