What's wrong with my Green Giant Arborvitae
Hello, I planted 30 Green Giant Arborivtae as a privacy screen last fall. They have all been doing fantastically until this week. We had a few days of near 100 degree temps, but got a decent amount of rain. One of the tress starting turning slightly brown and losing some of its foliage. The foliage is being replaced by a large number of cones, which may be contributing to the brown color. Any ideas what could be going on and what I can do about it?
