    Hey guys, I hope someone can help me, my leylandii hedge is starting to die back this year at home. just wondering if there is anything I can do to stop it? what is it or any information?

    It started about 2 months ago and has spread quite a bit, my neighbours hedge has started showing signs in one part of his hedge but that's nearly the furthest leylandii tree away from mine.

    I've checked it over for any aphids and can't seem to find anything.

    It looks like whoever is trimming the hedge is trimming it too tight, i.e. past the live foliage. It's a fine line between doing it right and inadvertently killing it.

    I agree, only the outer few inches are really alive with fresh growth, beyond that is old wood with no live greenery.

    The goal is to trim at the exact same level all the time, going tighter is never an option with this type of hedge.

    Tight trimming shouldn't be an issue though, we have always cut it back this tight and never had an issue until this year.

    My neighbours hedge is no way near as tight and it is also dying back in areas.

    Interesting, afaik there are no bacterial or fungal diseases that affect leylandii, so that leaves only a maintenance/pruning issue, or perhaps it could be wind burn.

    My first thought too was trimmed far too tight. I would also bet that it was trimmed too early in the year and hit with a late frost or trimmed too late in the previous year and hit by an early frost. A very common mistake.

    Such a lovely hedge though and a sad loss.

    Leyland are hardy beasts, with only something like honey fungus or over pruning killing them.
