I previously posted pics back in late winter of my 1st attempt at using the hack n squirt method for killing unwanted trees. I used a small hatchet, small hand sprayer and straight gly. Now that everything has leafed out, I went back in to the areas I used this method on and am very pleased with the results. Looks like I got a 100% kill on every tree, ranging from oak, sweet gum, winged elm and hickory. And some of these trees were quite large.
