Sorry Sawdog! But I think that is one of those old practices that was never really studied (i wonder why!) I asked my F-I-L whose dad was a tree guy in the old, OLD days (10ft double handled hand saws), he worked with his dad till he left for the big city (pop 40,000!lol!) He just started laughing, said it sounded like he should milk a bull too! I, by no means am claiming to know it all, but I have been studying this stuff for a good long time, read everything I can get my hands on, hit the books everyday for at least 2 hours, sometimes all day. I have never, EVER, heard anything about putting poop on a tree!, I would like to see some proof of it "healing" the tree. I am not making fun, just saying that it sounds like a old home remedy. If it works, maybe we should contact the ISA to get it entered into the Best Management books!
I can see it now
