I realize this is a gardening place but I because of the good wisdom and experience I have found from fellow monkeys - well - I hope no one will be offended with a question that is a bit off topic. I live in the Northwest, Northern Idaho, to be exact. I have 5 acres of beautiful pines and fir. Around the area lately, I have noticed lots of dead trees, all brown, gone. I have a few trees that have individual limbs that have gone brown (see photo) 1) What is this brown stuff? 2) should I cut off the brown limbs in hopes of saving the tree? 3) Maybe these brown limbs are normal? And, this not what I have seen like the dead brown trees in the area? I am going to ask around here also as know 2 excellent master gardeners one of has a lot of experience with trees but not sure I can hook up with him in the next few days so looking for all insight I can find.... Thanks!
