Leyland Cypress turning brown

[Ace12]

I have 5 Leyland Cypress trees planted in a row as a privacy barrier. One of them has started to turn brown on some of the limbs. Is this a disease or anything else I should be concerned with?

Could be any number of things. Pics would be helpful.

How long ago were they planted?

seiridium cardinale

Thats clearly seiridium unicorne

or Bot canker

could be drought damage

Mr. Seer's ability to diagnose causal agent from a written paragraph is second 2 none. He is a board certified master arborist. As such, he represents the best of what we have to offer in the form of advice.

BUT, just 2 b sure, call out a professional whom can diagnose or at least be able to take the neccesary samples needed for diagnosis from a qualified pathologist. The service is only $10 or so for in state residents.

Just so u know, there is no known curative or preventative treatment for seiridium.

Hi folks. I have 4 Leyland's Cypress trees that are all beginning to turn brown from the inside out. They are all 18'-20' tall and seemed to be doing well until this spring. I've read that it could be a pest, a disease, too much water, or too little water. I am just wondering if someone out there could tell me what they think. Any advice would be much appreciated. I really don't want to lose these trees but I am afraid I might be too late. Thanks in advance.
