Shothole is usually caused by the fungus 'Clasterosporium carpophilum' but sometimes other fungi and bacteria are involved. Damp humid weather conditions can contribute.
Plants affected are: Edible and ornamental cherries (Prunus), Peaches, Nectarines, Plums, Gages and Prunus Laurocerasus. Some other trees, shrubs and woody perneials may also show symptoms.
Symptoms: Discoloured, normally, brown spots appear on the leaves. Dead leaf tissue falls away leaving holes, giving a ragged appearance. When severe, large areas of leaf are missing.
Treatment: As plants lacking in vigour are normally affected, the best treatment is to feed and mulch around the base of the tree. If grass is growing directly up to the trunk of the tree, cut a circle in the turf around the tree to allow you to apply the mulch etc. After some time if symptoms are still apparent, a copper based spray may be used (Always follow manufaturer's instructions on the lable and take suitable precautions when spraying).
*** Garden Care tip: Always try the feeding and mulching option first and use sprays as little as possible to be kinder to the environment.
