Well, I'm still waiting to hear back from the Weed Board to more accurately pin down which hawkweed they are targeting. Then I hope to do a visual inspection when they might be in bloom and see how large (or hopefully small) of an infestation we might have. If we can manually wack them before they set seed, that may do it. If we have a whole hillside full, that will be a whole 'nother issue. I do know that both sides of the creek are pretty heavy in wild roses, which seem to choke out everything else.
