Question
I have at least 20 50ft. pine trees that seem to be dying.  Do I feed them muracid?  Obviously, I am new to the great outdoors.  We live in lower Michigan.  We have only lived here for 2 years.  I'm sure the trees are atleast 25 plus years.  Thanks for your time.

Answer
Susan,

White pines that big may need more than just fertilizer. For trees this large to start declining, I would suspect that there are either insect or disease problems. If these problems aren't addressed, no amount of fertilizer will keep the trees going.

I would recommend contacting a tree care company in your area to diagnose the problem and recommend the proper treatment.

Good luck,
