I planted two loblolly pines about 3 years ago and they have been doing great. We have had a terrible drought here, but I have tried to keep them healthy. The larger of the two really looked fantastic until a few days ago...it seems to me that overnight it has gone from a vibrant green to literally every needle has turned brown and is falling off. I have no idea what has happened. the other one planted maybe 20 feet away still looks good.
What could cause it to do this so fast?
I appreciate the help!
