What's eating my manhattan euonymus?
Euonymus scale (Unaspis euonymi)
Signs: Small white male and brown female scales on stems and leaf undersides cause yellow leaf spotting and stem dieback under heavy pressure.
Control: Apply horticultural oil at crawler stage in late spring. Prune out heavily infested branches and dispose of them promptly.
Aphids
Signs: Clusters of pear-shaped insects on new shoot tips and leaf undersides cause puckered growth; sticky honeydew leads to sooty mold on lower leaves.
Control: Blast off with a strong jet of water. Apply insecticidal soap or neem oil; introduce or conserve ladybird beetles as natural predators.
Deer
Signs: Foliage and soft stems are browsed, particularly in late autumn and winter when deer pressure is highest.
Control: Apply deer-repellent sprays regularly; use physical barriers around newly planted shrubs until established.
