Brown Leyland Cypress
I have a row leyland cypress' that have been in the ground for about 7 years, all of them are about 20ft tall. I have one that has turned completely brown. The branches are still flexible and will not break when bent and there is still a touch of green on some branches. No signs of insects. I have been reading online about diseases. I have a couple others that have brown branches on the bottoms.
Do I need to cut the one down? Or is there a way to bring back the green? No bag worms. I am familiar with these, but no bag worms. Wanted to know so if it is a disease I can get it down before it really affects the other trees, 15 of them.
Please look for small silver dollar size holes under the trees. Voles have been a problem this year on many trees and especially leylands. A shingle board test with an apple will also help you determine if voles are present and eating the roots.
