Watch out for

Vine weevil: Check new arrivals for grubs and use biological nematodes or systemic insecticides if infested.

Powdery mildew: Improve air circulation and apply fungicide only if severe; otherwise tolerate minor infections.

Bud blast: Remove and destroy infected buds promptly to prevent spread where practical.

Silver leaf fungus: Prune out affected branches well below the infection site and destroy them immediately.

Pieris lacebug: Encourage natural predators or use horticultural oil sprays during early infestations.
