Monterey Oak Tree #164847

Asked January 22, 2014, 11:12 AM EST

Good morning,   We live in a new housing development in Cedar Park.  Our home is 1-1/2 years old.  The developer planted two very nice Monterey Oaks in the front yard.  Once we moved in, we watered, watered and mulched the trees.  They were flourishing.  This past summer, one of the trees was attacked by a persistent Yellow-Bellied Sapsucker!  We wrapped the tree, hung Christmas ornaments on the limbs, etc.    Attached is a picture of the tree.  Do you think it can be saved?   Thanks so much,  

Williamson County Texas

My best guess is the tree was over-watered or watered to close to the truck and you now have root rot of some kind. Water only once each month, and water deeply. to the 6 inch depth.
If your lawn care was over-applying broadleaf lawn chemicals have them confirm they are using the least toxic chemical at the lowest rate. You may want to spray the lower part of the tree with an insecticide this spring to insure against insect damage- however I have not seen major insect damage on a Monterey Oak
