I just noticed that a large hemlock at the edge of our clearing appears to be dead. I didn't really notice it before and we don't have much history with the house, being here only since Jan. All the needles have fallen off except for a few, and I mean very few. The needles are on the ground, so I figure it's a fairly recent thing. Now, here is where I might have done it: I rinsed out the salt remains in my softener's storage tank in the Spring and might have dumped it in the general area. Could I have killed this hugh ~2.5-3' tree? I'm thinking it's not going to bounce back, but could it? Even though we have lots of trees I'm bummed that I could have unwittingly done this. No other trees, including other hemlocks, nearby are affected.
