What's eating my amydrium medium?

Amydrium medium, a rare climbing aroid, shares the same indoor pest pressures as its Monstera and Epipremnum relatives. Spider mites and mealybugs are the primary threats, especially in dry indoor air. Wiping leaves regularly and maintaining moderate humidity dramatically reduces infestation risk.

Pale yellow speckling on leaves; webbing across undersides and between nodes on the climbing stem Increase ambient humidity; spray neem oil or a miticide (e.g., pyrethrin-based) every 5–7 days for at least three treatments

White waxy clusters at the base of leaf stems and in crevices along the support; sticky residue on lower leaves Treat with isopropyl alcohol on a swab for spot control; apply neem oil drench to soil and foliar spray weekly for a month

Hard brown bumps along stems and petioles; affected areas may die back; honeydew attracts sooty mould Manually scrape off scale; apply horticultural oil thoroughly; repeat every two weeks until no live crawlers are visible
