Hello all,
I have about 20 white pine trees planted last year. I've been told I have
pine tip borers. The tips at the top are turning brown, plus I can see
holes in the trunk near the top of the tree.
Is this something I can take care of myself by spraying? If so, what should
I use to get rid of them? How often should I spray?
Thank you.
