What's eating my jungle geranium?

Ixora coccinea is most troubled by spider mites in hot dry indoor conditions and scale insects on stems. Mealybugs colonise new growth and leaf axils. Outdoors in tropical climates, aphids attack flower clusters. Maintain consistent humidity and avoid water-stressed conditions to reduce mite flare-ups.

Pale, bronze-stippled leaves with fine webbing on undersides; affected leaves drop in severe cases, especially indoors in dry air. Increase humidity; shower the plant to dislodge mites; apply insecticidal soap or neem oil to undersides of leaves; repeat weekly.

Hard or soft oval bumps clustered on stems and leaf midribs; plant looks stunted with sticky, honeydew-coated leaves. Remove by hand or soft brush; apply horticultural oil or neem oil to coat crawlers; repeat after 14 days.

White cottony clusters in leaf axils and at stem tips; new growth distorted; honeydew attracts sooty mould. Dab with isopropyl alcohol; spray with neem oil or insecticidal soap; isolate the plant to prevent spread.
