I have three huge pines in my yard that I know are over 50 years old and one is showing signs of disease/pests. From what I can tell from a quick research is that it is infested with the Southern Pine Beetle. I was wondering if there was anybody who had dealt with them before and if the tree can be saved once the needles have turned brown. Weird thing is that it seemed to happen really quick. I guess after seeing them every day I didn't pay much attention till just a few days ago. Any experience?
