Pests and diseases (5)
Problems recorded for this plant, most serious first.
Waterlogging Root Decay
MajorDisorder
The plant wilts even though the soil never dries, and the lower leaves yellow. Pull it up and the roots have turned brown to black with a distinctive rotten smell.
Fertilizer Burn
MajorDisorder
Leaf margins scorch brown soon after fertilizing and the whole plant wilts. Root tips turn brown and growth stops abruptly.
Scale Insects
CommonPest
Small white or brown shell-like insects dot the shoots and leaves. The plant loses vigor and honeydew-fed sooty mold blackens the shoots and 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.
Aphids
OccasionalPest
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.
