What's eating my hoya leucorhoda?

Hoya leucorhoda is a rarer hoya species grown indoors for its attractive foliage and flowers. It shares the same pest vulnerabilities as other hoyas — mealybugs are the primary concern, with spider mites a secondary threat in dry homes. Keep the plant in good air circulation and check stems and leaf undersides every two weeks.

White cottony wax deposits at stem joints, leaf axils, and around flower spurs; sticky honeydew on lower leaves Spot-treat with isopropyl alcohol; apply a neem oil or insecticidal soap spray to the whole plant and repeat every 7–10 days

Stippled, dull, or bronzed leaf surfaces; fine webbing on undersides particularly in low-humidity conditions Rinse leaves, raise humidity above 50%, and spray with neem oil or insecticidal soap weekly for three weeks

Flat or domed brown bumps on stems; yellowing foliage and honeydew secretions Remove manually with a toothbrush, then apply horticultural oil spray weekly until no new crawlers are seen
