Leylandii hedge moss control

Zone Gartocharn near Loch Lomond | Anonymous added on March 22, 2020 | Answered

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

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:
