What's eating my wandae staghorn fern?

Wandae Staghorn Fern, one of the largest staghorns and typically grown mounted, faces scale insects as its primary indoor pest. Mealybugs hide beneath the broad shield fronds. Spider mites occasionally colonize the large antler fronds under dry indoor conditions. Because of its size, early detection via monthly inspections is essential — large plants are difficult to treat once pests establish.

Brown armored bumps on antler frond stalks and undersides; honeydew leading to sooty mold; frond yellowing Dab scales with isopropyl alcohol on a cotton ball; apply neem oil spray to antler fronds; repeat every 7–10 days

White powdery or cottony clusters under shield fronds and at mounting points; reduced vigour and frond browning Carefully lift shield frond edges and remove with alcohol swab; treat with insecticidal soap; isolate if possible and repeat weekly

Stippled, dull upper frond surfaces; very fine webbing between frond lobes; worst in low-humidity environments Increase room humidity; wipe fronds with a damp cloth; apply neem oil or insecticidal soap every 5–7 days for 3 treatments
