Prunus laurocerasus guestion
I have several Otto Luyken shrubs that are suffering some kind of disease. I think it might be anthracnose but am not sure. The leaves are turning brown almost as though they are sun scorched. They get full sun most of the day. Do you know what the cause might be? Is there a treatment available? Thank you.
This looks like cold damage/winter injury. Wait until spring to prune affected foliage. You can send more photos if there are additional symptoms.
