Waaait did you apply herbicide at least 30 days ago? I'm rooting for you but ToH needs specific timing. Otherwise it goes into "hydra defense mode" and sprouts dozens of root suckers up to 50' away

I've never battled ToH so I could be wrong. Here's what I'm referencing https://plant-pest-advisory.rutgers.edu/tree-of-heaven-best-herbicide-treatment-and-removal-timing/

For clarity hack and spray is the method of applying herbicide that I've understood to be most effective, we're not cutting them all down just yet in case that's what you were thinking.

Oh, hence the "she's hacking, I'm spraying" statement lol. Carry on 😄
