I HAVE VERY LARGE OLD OAK TREES ON MY PROPERTY. THE ONE IN THE FRONT AS WELL AS MY NEIGHBORS ON EACH SIDE OF ME HAVE OAKS THAT LOOK LIKE THEY ARE DYING. MY TREE LOOKS THE WORSE SO FAR. I AM NOT CLEAR WHAT IS CAUSING THE DECLINE OF MY TREE AS WELL AS MY NEIGHBORS' TREES. CAN YOU PROVIDE ASSISTANCE AND HELP IN THIS MATTER?
THE FIRST PHOTO IS OF MY TREE. THE SECOND PHOTO IS MY NEIGHBOR'S TREE TO THE LEFT OF MY HOUSE. THE THIRD PHOTO IS MY NEIGHBOR'S TREE TO THE RIGHT OF MY HOUSE. PLEASE ADVISE. THANK YOU, ROBYN
Take a look at the following publication about oak decline. https://www.na.fs.fed.us/spfo/pubs/fidls/oakdecline/oakdecline.htm
The symptoms you are seeing now are likely due to a variety of stressors that have accumulated over the years -- drought and heat stress among them. Drought is especially tough on mature trees like this. Trees in urban areas also have the stresses of soil compaction and air pollution. Most likely it is a complex of factors at work. Weaken trees then become more susceptible to insect damage, root rot, etc. There isn't really much you can do to "reverse" decline in mature trees like this, unfortunately.
