Symptoms and damage

Bacterial problem One of your pictures suggests that the laurels are affected by a disease caused by bacterial pathogens (Xanthomonaspruni). This disease typically starts in early summer with little, brown sores appearing on the undersides of leaves. The spots grow and develop red borders and yellow halos. The spots eventually fall out of the leaves, leaving behind gaping holes and tattered leaf tissue. Many infected leaves look as though someone peppered them with buckshot.

Management

Because chemical control of shot hole disease is hard to achieve for home gardeners, help prevent this disease from occurring by planting the shrub in a well-draining location. Prune out and destroy any infected plant tissue as soon as you notice it. Rake up fallen plant litter to prevent pathogens from being attracted to the area near your shrub.
