Hack n Paint with Stump Out
Hello! Looking for advice trying to use "stump out" brand triclopyr to kill TOH. We did round 1 hack n paint and basal bark application 2 weeks ago, and just went out for a reapplication. Mother tree is around 8 inches in diameter, we've scored into the green cambium layer to make 2-4 inch sections round the base of the tree (not in a perfect ring, staggered along the height) and larger offshoots. Painted stems and leaves of smaller offshoots.
All the offshoots are showing herbicide damage on new growth, but aren't dead yet. New offshoots are popping up with herbicide damage (pic 2 - peep the brown-black "burning" and malformation on the lower right leaves.
My question is, are we doing enough? Do we need to use stronger stuff or keep reapplying? Is 2 weeks right or should I do weekly?
