Is your Mesquite or Acacia dying from Borer's? Well I would have put a picture of the evidence but it is hard to get a good picture that shows up on camera. The picture beside is a tree that was topped (an unrecognized practice by the ISA). The end result will be a lot of boring insects tunneling into the cambium layer from the excessive damage.
How do you know if your tree is damaged? Well very simply look for little gold sap bubbles on the bark of the tree. Generally these will be above head level on the large branches. These little gold sap bubbles are a sure sign that a borer has gotten in. Once in it will tunnel holes in the cambium layer and prevent the flow of nutrition eventually weakening the tree until it succumbs to other micro organism's, pest's and environmental factors. Do not be confused, black sap running from a mesquite is natural, not a concern, but the gold sap bubbles not. On sweet acacia's it is a little different as the little sap bubbles are actually a darker sap and not a hard gold bubble like the mesquite. An experience Tree Trimming company should be able to point them out.
