|I have forty-five, twelve foot, Arborvitaes in a row on the edge of a ten foot drop. The inside of which looks green and very healthy, as opposed to the outside which seems to have sustained what I can only guess as windburn, and lots of brown ends. Would this be a good time to trim windburn off one side of an Arborvitae wind barrier?
|You can shear off the dead growth anytime between spring and midsummer. This should spur new growth to replace what was lost. You have a lot of trees, but it may be worth your while and some money to treat them with an antitranspirant spray next fall before winter sets in. Also, if fall rains are scarce, water the trees well before the ground freezes. That way they'll be better able to resist windburn. Best of luck to you!|
