Kathleen asked 6 years ago

My Leylandii hedge is turning brown like if it’s dying. Can you tell me what might be wrong it’s about 18 years sowed?

Leyland cyress can turn brown for a variety of reasons.

If the whole tree, part of a hedge, turns brown, it is likely to be a root rot.

If patches die, it could be greenflies, or fungus disease, or it could be due to very heavy clipping that allows little or no annual re-growth.

Brown patches may get worse and will not recover, unless adjoining green parts grow in.
