I’ve seen a lot of deer browsing on weeds. I have a long shooting lane that I plant in a wheat,rye , Bob oats , winter pea mixture and it goes to a small creek then on the other side is 200 more yards of south hillside glade with shelf rocks and wouldn’t grow the stuff so I just brush hog it. Every year deer come out and browse on something in that glade area and they don’t just nibble around and go on. They stay there and act like they like it. I’ve seen a lot of deer browse ragweed earlier in the year also.
