WOOD How To Kill a Tree Hack and Squirt

Old school forestry guy. This is the one i'm going w/ this year. Trying the 20% copper sulfate 80%water mix. Squirt bottles sketchy... Maybe a dish soap thingy... Eh, we'll see! Then there was the bit where my lack of chemistry skills came into play--had an extra word going in... Oi!

10/11/24 Update: Going well w/ the formula: 2 1/2 cups per 1 gal H2O. Shave a bit off w/ chainsaw or sharpened putty knife. Trees dying from top down. Many not happy in 3days. Used the dish soap bottle w/ dab of soap in to beat the tension. Thinking of hitting them again w/ some ink salvaged from a printer mess. The colour now is green/blue. If i make it black/red i will see the progress. Lord willing & weather...
