Pests and diseases (3)
Problems recorded for this plant, most serious first.
Spider Mites
MajorPest
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.
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.
Powdery Mildew
CommonDisease
White patches appear scattered on the upper leaf surface at first, then the whole leaf is coated in a white powder. Leaves later yellow, brown and die back, and reduced photosynthesis cuts growth and yield.
