What's eating my epiphytic zamia?
Scale insects
Signs: Armored or soft scale clusters on stems and exposed root bases; drains sap and causes yellow, weakened fronds.
Control: Manually remove with a brush and rubbing alcohol; apply neem oil or horticultural oil spray every 10 days until absent.
Mealybugs
Signs: White waxy colonies in stem crevices and exposed root zones; honeydew residue promotes secondary mold infections.

Spider mites
Signs: Pale stippling and webbing on leaflets when ambient humidity drops; more problematic in heated indoor spaces.
Control: Raise humidity to 60%+, rinse foliage, and apply diluted neem oil or a registered miticide every 5–7 days.
