Anyways, so every tree I plant I surround by a layer or two of cardboard, then i cover it with a few inches of manure. I also did the same for our raspberry and blueberry patches
that's about the opposite way of what i would do with it. cardboard over the manure. woodchips or rocks to hold down the cardboard.

they certainly were available. I can remember my Daddy trying them. His mantra; it will either burn them up or make 'em go! He also used sevin dust, then decided to go back to the old ways, like he was raised--you know BEFORE such things became available.
