Of course you want to say that nothing is wrong, this is just something having to do with the season.... but its getting to the point where I may have to tell myself I'm in denial. I've seen this happen about five years ago, possibly not this bad. I do not know what the cause was, or what resolved it. Is it drought stress? Because I don't think its been particularly dry. Lately it has just started getting chilly in the Midwest, lows in the 30s but nothing drastic. It seems urgent action is needed. But, the wrong remedy could be fatal, sometimes its best to leave things alone. Anyone have any thoughts? This tree would be an utter disaster to die, both in cost of removal and homeowner value. Not to mention, just plain tragic.
