Question
Good morning. I live in Maryland and have 7 Leyland Cypress trees in my front yard. Recently one of them has been turning brownish yellow beginning at the top and spreading down. They are about 5 years old, 15-20' tall, and on flat land. It's looking as if a couple more are starting to turn at the top as well. Any Ideas?

Answer
Irene,

It is hard to say without actually seeing the pattern of damage, and the specific site issues that may be present. I would recommend calling a tree care company to make a visual inspection of the area and prescribe the proper treatment.

Good luck,
