I have a Post Oak tree near Lake Fork that suddenly turned all of its leaves yellow in the last few days.

There is a house with a slab foundation about 25 feet from the trunk, but its been there for ten years. There has been no new activity around the tree.

With all the rain last month, we did have water standing near the tree for a few days until it evaporated. We've only been in this house six months, but it looks like standing water in that area is not a new problem.

What can I do to save this tree?

Thanks

How's it doing now?
