I have a white pine that's about 60 years old, and aside from occasional crowding and snow damage, it's appeared healthy. I've been seeing a lot of brown needles going all the way up the tree. Our spring has been pretty wet. Winter was warm, and from memory, maybe a little wetter than usual. Soil probably isn't ideal with a high clay content. Any ideas on what's wrong? Anything that can be done without chemicals? Maybe just wait if it was waterlogged? It would be a fun project taking it down, but I like the tree well enough, and would prefer it stayed.
