My in laws have a few small fields that have not been grazed in years but with a little TLC could be useful. While dandering around them earlier I spied a couple of weeds which I’m unsure of and as to whether they are poisonous to livestock. Pretty sure one is cows parsnip as opposed to hog weed, but have no idea about the other. Any thoughts? They’re the sort of fields which would need grazed a bit before you might have success with a herbicide.
