Seems like glyphosate doesn't do very good on anything woody, also I don't think it's suppose to. But if you cut something off and douse it in glypho it seems to do a pretty good job killing it..

What's some plant examples it won't control, just curious?

I believe in catch and release. I catch then release to the grease..
