Prunus × cistena · Shrub
Silver leaf: Remove and burn affected branches well below the visible symptoms to prevent spread.
Powdery mildew: Improve air circulation and apply a fungicide if severe; avoid overhead watering.
Leaf spot and canker: Prune out infected wood during dry weather and dispose of fallen leaves to reduce inoculum.
Slugs and snails: Use physical barriers like copper tape or apply iron phosphate-based pellets around the base.
Vine weevil: Apply systemic insecticides to the soil in autumn to control larvae before they pupate.
