I mixed my gly with water 2:1, just enough water to help it squirt easier. I found gly 35$ for 2.5 gallons, so I wasnt going to worry too much about using a little extra gly. I tried both the axe and machete, but found the axe was harder to hit the trees surrounded by brush(all my trees are surrounded by thick brush). Everything caught the handle and made it harder to get good contact. The machete blade cut through the brush and still made good contact through the trees to reach the cambium layer.
Each tree received 1 hack for inch thickness of the tree. I used the machete to leverage open the cut, squirt the gly and then release the cut to hold the gly into the wound. I focused on a half acre block that was missed by the loggers and about 2 acres along a creek bottom.
Dont know how long it will take to see the effects, but will come back and update when I do.
