Why are my viburnum leaves turning brown at the edges?

Our Advice:

Brown edges on viburnum leaves can be a sign of leaf scorch, which is caused by exposure to high levels of light or heat. It can also be a sign of salt damage, which can occur if the plant is exposed to too much fertiliser or salty water. Brown edges can also be caused by leaf spot diseases, which are fungal or bacterial infections.
