What's eating my white wizard philodendron?

White Wizard Philodendron, with its dramatic white-on-green chimeral variegation, is vulnerable to thrips, which scar the white leaf sections and reduce the plant's ornamental and resale value. Mealybugs hide in the stem sheaths. Spider mites attack if the air is dry. Regular inspection and strict quarantine are essential.

Silvery or rusty streaks on white variegated panels and green sections; deformed new leaves; dark frass specks on undersides Isolate at first sign; remove most-affected leaves; treat with spinosad or insecticidal soap every 5–7 days; blue sticky traps help catch adults and monitor progress

White cottony colonies inside stem cataphylls, at leaf nodes and petiole bases; slow growth; sticky honeydew on leaves Use a cotton swab with 70% isopropyl alcohol on each colony; spray with insecticidal soap; re-check inside the cataphylls at every watering

Fine pale stippling across leaf surfaces; thin webbing along stems; visible in low-humidity conditions near radiators or vents Raise ambient humidity; shower the plant to knock mites off; apply neem oil or insecticidal soap spray every 7 days
