What's eating my philodendron birkin?

Philodendron Birkin is most commonly affected by mealybugs, which shelter in stem nodes, and by thrips, which scar the distinctive white-striped leaves. Spider mites can appear in dry conditions. Because the white variegation can obscure early damage from thrips, inspect leaf undersides and nodes at every watering.

White cottony deposits at leaf axils and stem internodes; honeydew residue; leaves yellow near colonies Remove with alcohol swab; spray insecticidal soap to all stem joints and undersides; isolate the plant

Silver-bronze streaks and scars on the leaf surface; distorted new leaves; tiny dark frass on undersides Isolate immediately; remove heavily damaged leaves; spray spinosad or insecticidal soap every 5–7 days for 4–6 weeks

Fine stippling on leaves, especially in dry indoor air; webbing visible at stem joints Wipe leaves with a damp cloth; raise humidity; apply neem oil or insecticidal soap weekly until gone
