Way to many for that. I sprayed 4 gallons of crossbow and roundup mix on probably 25 or 30 this afternoon and barely got a good start. I'll see if this works. The crossbow is supposed to kill brush.Asian honeysuckle. Cut them off at the ground and paint the trunks with herbicide. I believe the one I see everyone talking about is Toradon or something like that. We have a few here but not a horrible amount. It is nearly impossible to eradicate from what I have read.
