What's eating my philodendron 'prince of orange'?

Philodendron 'Prince of Orange' is an indoor aroid primarily attacked by mealybugs in its leaf sheaths and by thrips that scar its vivid orange new leaves. Spider mites appear in dry air, and scale can colonise mature stems. The spectacular emerging foliage is the most vulnerable part, making early detection critical.

White cottony deposits in leaf axils and along petioles; honeydew, sooty mould, and stunted growth Swab with 70% isopropyl alcohol, spray with neem oil solution, and repeat every 7 days; isolate the plant

Silver streaks, brown scarring, and distortion on new orange leaves; tiny fast-moving insects visible on foliage Remove heavily affected leaves, apply spinosad or insecticidal soap spray; use blue sticky traps to monitor

Fine webbing and pale stippling, especially on undersides of mature leaves Raise humidity, shower foliage weekly, treat with neem oil or insecticidal soap on a 5–7 day cycle
