What's eating my amelanchier × grandiflora 'robin hill'?

Amelanchier 'Robin Hill' is most threatened by aphids clustering on new growth and caterpillars (particularly winter moth) chewing leaves in spring. Birds feast on the berries, and sawfly larvae can skeletonize foliage. The best defense is encouraging natural predators and monitoring shoots closely in early spring.

Distorted, sticky new shoots; honeydew leads to sooty mold on leaves Blast off with a strong water jet; introduce or encourage ladybirds and lacewings; insecticidal soap spray for heavy infestations

Ragged holes in young leaves in spring; flowers and fruitlets may be eaten Apply grease bands around the trunk in autumn to trap wingless females; remove caterpillars by hand; use Bacillus thuringiensis (Bt) spray

Skeletonized or heavily notched leaves from late spring onward Hand-pick larvae; spray with pyrethrin-based insecticide in early morning; encourage ground-feeding birds

Berries stripped before they fully ripen Net individual branches if crop matters; in ornamental settings birds are generally welcome wildlife
