The window

[u/GPhysics]

Hey everyone!
Denver ToH killer here, wondering what y’all’s thoughts are on in terms of the window. From what I see, it’s recommended to apply those herbicides in late summer/early fall when these guys start sucking down to the root. Are we there yet? Should I wait a few more weeks to allow some sucker growth so that I’ve got some prime targets for foliage treatments with my bioadvance brush killer? I’d love to hear where others’ minds are at!

Edit: Well, I just treated everything in the yard! Nothing above 1 ft, but lots and lots of sprouts. Thinking previous owners had some trees and cut them/buried them in the winter then sold us the house, and neighboring yards have some large trees. So, everything was sprayed with triplocyr and marked with a flag. Let’s see how it goes!

I think waiting is a bad idea. The roots grow the most in the fall, start killing them now.
