Yellowing White Pine Needles
On Oct 1st I put in six evergreen tree fertilizer stakes and, today, Oct 4th, I noticed that our white pine tree needles were turning yellow in droves. I wanted to know if anyone could help me diagnose whether this is directly related to the fertilizer stakes (I took out the stakes that I could find, but they were more than half gone at this point). Also, does this look normal and, if not, is there anything I can do to help my trees? I appreciate any help and all replies. Thank you.
