What's eating my kolkwitzia amabilis?

Kolkwitzia amabilis (beautybush) is a robust, low-maintenance shrub with relatively few serious pests. Aphids occasionally colonize new growth in spring. Scale insects can develop on older bark. Deer may browse young shoots, and in the UK, spider mites can cause bronzing in hot, dry summers.

Soft colonies on shoot tips in spring; sticky honeydew; slightly curled or distorted new foliage and flowers Remove by hand or water jet; apply insecticidal soap or neem oil; attract ladybirds and hoverflies

Waxy brown or grey bumps on bark and older stems; branch yellowing and dieback; sticky honeydew residue Scrub off with a stiff brush and soapy water; apply dormant horticultural oil in late winter; prune badly affected wood

Ragged browsing of young shoots and developing flower buds in spring; lower stems may be stripped in winter Protect with deer fencing or wire guards when young; apply deer repellent spray seasonally

Pale bronze stippling across leaves in summer; fine webbing on leaf undersides during prolonged hot, dry spells Spray plants during dry periods to increase humidity; apply neem oil or horticultural oil; ensure adequate soil moisture
