We have a huge crop of sand burrs which I would love to attack with a torch but we had the fire department out here to put out a grass fire last fall so setting my pastures and fences on fire doesn't seem like a great move.
I wish I could train the goats to eat them.
There are poisons that will kill them but I'm not ready to saturate the ground where my animals live with toxins. We have enough of those in the environment as it is.
That cycles me back to fire. Not ready to do that quite yet either. Hmmmmmmmm.
