What's eating my hoya fungii?

Hoya fungii's large, heavily-textured leaves and vigorous vines are most commonly targeted by mealybugs, which find shelter in stem nodes and leaf bases. Spider mites appear in dry rooms, scale insects cling to the woody older stems, and aphids occasionally attack emerging growth. Preventive neem oil treatments every 4–6 weeks deter most infestations.

Cottony white deposits at nodes and leaf axils; honeydew leads to sooty mould on lower leaves Treat infested spots with isopropyl alcohol swabs; spray entire vine with neem oil; re-inspect every 7 days

Pale stippling on dark green leaf surfaces; webbing beneath leaves; leaves dull and dry at margins Shower plant to dislodge mites; spray with insecticidal soap or neem oil weekly; keep humidity above 40%

Raised brown waxy bumps on older stems; sap loss causes yellowing and poor flowering Manually remove with a swab dipped in alcohol, then treat with horticultural oil; check every 2 weeks

Clusters on tender new growth tips; leaves curl and feel sticky Dislodge with a water spray, follow with insecticidal soap treatment; repeat every 5–7 days
