I just built a new house and have a large post Oak that measures 13feet 9inches around with two trunks 5to6feet in diamature I have overwatered this tree and planted grass up to base. the tree is turning yellow I have stopped watering and have removed grass 2feet around it.I live in Texas 60 miles south of Dallas.Is there any thing else I can do to help this tree come back or will it come back? Thanks for any help with this problem. My number is 903 875 0227 WJ

WJ sure sounds like a nice old Q. stella you have at your new home. ..or rather a new home at your old Q.stella.The yellow could be chlorisis or lack of iron. Swimming pool drain close by? My first thought is about the amount of construction interference your root system suffered by dozers and trenchers. It sounds like to nice of a tree to lose. Consider looking the yellow page in tree service for an ISA Certified Arborist and have a professional evaluation done in the very near future. It's best to have one on hand prior to construction around your old trees. Somebody help his old tree!!!!!
