What's eating my philodendron hederaceum 'rio'?

Philodendron hederaceum 'Rio' has the same pest vulnerabilities as the species but its bold cream-and-green variegation makes pest damage particularly noticeable. Mealybugs and thrips are the primary concerns, with thrips scarring ruining the ornamental variegated leaves. Spider mites also appear in dry rooms. Monthly inspections and prompt isolation of affected plants are essential.

White cottony clusters at nodes and leaf axils; sticky honeydew coats the decorative variegated foliage and slows growth. Dab with isopropyl alcohol; apply neem oil spray every 10–14 days for 4 rounds, reaching all stem joints.

Permanent silver scarring on variegated leaves; new growth unfurls deformed; tiny dark specks of frass are visible. Isolate immediately; remove badly scarred leaves and spray with spinosad or insecticidal soap every 5–7 days for 4 weeks.

Fine pale stippling across leaf surfaces, most obvious on cream variegated sections; webbing in dry heated rooms. Boost humidity to 50%+; wipe leaves and spray undersides with neem oil or insecticidal soap weekly until clear.
