Something is killing my grapfruit and orange trees in my yard.  The branchs die off really quickly. It appears like something is getting under the bark.  My grapfruit tree has a large splotch where there is an opening and the sap is running out.  There are cracks in the bark running up the tree.
Can someone get me to someone that can help me with this.  This same thing happened to my Shammel oak tree a few years ago and it died completely.
