Leylandii hedge moss control

Question

Just moved in to property with a large garden with long lengths of trimmed Leylandii hedges. They are dying because of infestation of moss growth on the top. Large clumps, size of a dinner plate can be lifted off. We have cleared as much as we can, but I wondered if there was a chemical i.e. sulphate of iron I could spray on to eradicate it. If so what mixture quantities? I can send photos if necessary, but would have to get advice on the ‘how to’ as my internet skills are very limited

Answer 1

Our experts suggest either pruning or treating the hedge with an organic or copper based fungicide. Here's a link to an article about unwanted moss on foliage:
