Have y'all had much success using straight glyphosate with hack and squirt. I have a partial jug and wanted to use it up instead of buying a jug of arsenal. Elm, ironwood, gums, and red maple are the target species.
I didn't use it straight, but last year I used a heavy dose of cornerstone and crossbow mixed up and none of the thorn trees I sprayed died. Actually, other than weeds and briars, I don't think it done anything to any bushes. Someone here had a video on the chemicals to use but it's slipped my mind on what was actually recommended. But it was 2 herbicides.
The Dr. Craig Harper Cocktail:
I've got some big beeches double girdled, hack and squirted, drilled & herbicide applied, and girdled and squirted. Going to have to wait and see if they leaf out this spring and figure out if any method is successful.I use a 50% glyphosate concentrate and 50% water. Kills pretty much anything but not mature trees of any species. So far, I've found NOTHING that will kill mature trees, including double girdling.
I've had extremely poor results from Garlon 4A. Wouldn't kill anything. I've even tried mixing it with Imazapyr and glyphosate and none of those mixtures worked as well as just glyphosate concentrate.BSK, not even Garlon 4a? I've had great luck with it on thick barked trees like beech, maple, myrtle, and privet. Diesel as the carrier/penetrant it'll smoke those species.
What concentration of Garlon 4?In the last few years I have killed literally thousands of trees on my property (sweet gum, red maples, beech, black gum and privet) with outstanding success. From saplings to monster sweet gums.
Garlon 4 for hack & squirt
I had this happen on virtually every tree I H&S last September with Triclopyr. It frustrated me so much - I treated about 2 acres. I have some huge projects coming up in October. I even went and bought a small arborist chainsaw for girdling and doing this every fall. Now it is just making the right herbicide concoction.And I have one tree that is on it's 3rd attempt! Weird that on each of the previous ones the tree vomits up that sweet smelling yellow goo, and areas around the hack start to rot, but the darned tree will NOT die! But that is a very rare exception.
