I have 6 acres in Kentucky and have quite a few cedar trees in the woods and many are pretty good size, going 15 to 20 ft. tall. In the past couple of weeks I've noticed several of the larger ones and many of the smaller ones turning brown and look as if they are dying. I haven't heard of any blight or pests here in Kentucky. I've checked and don't see any apparent pests around. Has anyone heard of a problem that's causing cedar trees to turn brown?
