What's eating my philadelphus 'snowbelle'?

Philadelphus 'Snowbelle' is troubled primarily by aphids, which colonize soft new shoots and flower stems in spring. Leaf roller caterpillars web foliage, and leafhoppers cause pale stippling on leaves through summer. Deer will browse young growth and flower buds in gardens close to woodland edges.

Sticky honeydew on shoot tips and leaves; curled new growth; ant activity at base of plant indicates infestation Dislodge with water jet; apply insecticidal soap or neem oil; attract ladybirds and parasitic wasps

Webbed, rolled leaves sheltering feeding caterpillars; browned and distorted foliage on affected shoots Hand-remove and destroy rolled leaves; spray Bt at caterpillar stage; maintain good air circulation

Fine pale stippling across leaf surfaces from late spring; leaves take on a dull, mottled appearance Spray with insecticidal soap; encourage diverse planting to support natural enemies; avoid over-fertilizing with nitrogen

Ragged torn browsing on new shoots and flower clusters, especially from late winter to early spring Use deer fencing or motion-activated repellents; apply commercial deer repellent spray and reapply after rain
