my laurels have holes in the leaves...i dont see any pests...what might cause this and what should i do? |
English, or cherry laurel, as it also is known, can have leaf holes for a couple of reasons. Probably the most common source is either a bacterial or fungal pathogen. The leaf spots begin as the characteristic target-spotlike lesions on the leaves, but the term "shothole" refers to the tendency of the spot to fall out of the leaves. The result is irregularly shaped holes in the center and on the sides of the leaves. Cherry Laurel also can show shothole symptoms resulting from cultural or environmental stress, although a specific cause for this has not be determined. To control the problem, clean up affected leaves and ensure good air circulation, but before spraying, ensure the problem is caused by a bacterium or fungus so look for leaf spots as well as holes in the leaves. Good luck with your English laurel! |
