Sudden Leyland Cypress Yellowing/Dying?

Hi everyone.
Happy New Year to you all.

We have noticed in the last month or so that a couple of our leyland cypress shelter trees have suddenly gone yellow, with quite a lot of foliage fall. More recently our neighbour on the other side, has also got a tree that looks to be doing the same. I have heard that they can be subject to some diseases. It does seem to be selective at the moment, with just these but am concerned we might lose the whole hedge. Any thoughts?

Thanks

Yes they get canker, and particularly when they are under stress, drought or too wet, you can try to prune out the effected branches bearing in mind that pruning will put them under stress....burn the prunings
You can get canker resistant varieties so you could replace affected trees if the hedge is not too old.

If it is a windbreak, plant replacement hedge on the downwind side and once this is established rip the Leylands out....

Probably Canker, which is why many of these shelter belts are dying out

If it is canker you should be able to see some of the bark around the root collar flaking off exposing the wood below. It could also be magnesium deficiency if conditions are good for the tree to experience growth. Could also be drought stress if too dry. Our macro's which must be around 90 years old show yellowing of the branch tips when it is too dry.
