Hi everyone, I'm new here and could use some help with a 5-10 year old 20' red oak tree in my yard. It was healthy until last summer, when I noticed the top branches were bare.
Since then I've watered it fairly often, but Spring has rolled around and now fully the top half of the tree has no leaves. The rest of the tree bloomed normally and looks healthy, with no signs of disease or insects.
Any idea why this tree is dying? Is it worth saving at this point? If I were to try and save it, should I prune the non-leafed branches off (this would basically cut the tree in half)?
Any help would be appreciated. Thanks!
