What's eating my finlaysonii wax plant?

Finlaysonii wax plant (Hoya finlaysonii) has large, strikingly veined leaves that attract the same pests common to all Hoyas indoors: mealybugs are the biggest threat, followed by spider mites in low humidity. Scale can establish on its thick stems. Inspect leaf vein junctions and petioles where mealybugs prefer to hide.

White waxy deposits in leaf axils, along veins, and at stem nodes; honeydew and sooty mould; slowed growth Swab colonies directly with 70% isopropyl alcohol; spray all surfaces with diluted neem oil weekly; repeat for at least one month

Fine stippling across the large leaf surface, especially prominent on light-coloured veined areas; webbing on undersides Increase humidity; shower the plant to remove mites; treat with insecticidal soap or neem oil every 5–7 days

Hard brown bumps on stems and midribs; sticky deposits below affected areas; reduced plant vigour over time Scrape off manually with an old toothbrush dipped in alcohol; follow up with horticultural oil spray every 10–14 days
