Pests and diseases (3)
Problems recorded for this plant, most serious first.
Root Rot
MajorDisease
Fine roots rot brown to blackish brown, growth stops and the lower leaves yellow. The plant wilts easily in the daytime and eventually dies outright.
Aphids
CommonPest
Small green or black insects cluster on shoot tips and leaf undersides, crinkling the leaves and stopping growth. The honeydew they excrete supports sooty mold that blackens the foliage.
Spider Mites
CommonPest
Fine white stippling spreads across the upper leaf surface, and the leaf eventually whitens and dies back. In heavy infestations fine webbing appears on leaf undersides and shoot tips.
