I was going to chime in on the chips, but had a thought. I dunno what you want to use them for Walnuts but I wanted to throw them around the yard here and there for weed inhibition. So, I wonder if chips partially from diseased, dying, or dead (from who knows what) trees is such a good idea after all.
I can't believe they did 3000 trees in such a short, to me anyway, time. Great job by one and all.
