I Live in zone 5/6, I have had a Tri-colored Beech tree for over six years. It was a beautiful tree, until last summer. I noticed the leaves start to brown up more than usual in the late summer month of August. Then by September all the leaves had died. I have left the tree till now in hopes of it might come back in the Spring, Nope. I would like to get another but not if it is going to die in six years. It was planted in morning/afternoon sun, late afternoon shade. Didn't see any bores in the trunk or bugs on the leaves while they were still alive Any Ideas Thanks
