Signs: White waxy tufts at spine bases and along stem ridges; honeydew leads to sooty mold
Control: Spot-treat with isopropyl alcohol on a swab; apply neem oil spray to all stems (use gloves — latex is irritating); repeat weekly
Spider mites
Signs: Tiny pale speckling on stem skin; faint webbing in very dry indoor conditions
Control: Spray with insecticidal soap solution; reduce indoor temperature if possible; ensure adequate air movement
Root mealybugs
Signs: Gradual wilting and colour loss without obvious above-ground pests; waxy powder at roots on inspection
