I am dealing with several invasives (mostly non-native) on my property. We are hoping to tackle it hard come fall. I would like to try using a Weed Wrench, but they are quite expensive. (Many reputable groups attest to their value; it's a budget issue for me.) I am aware that some communities have Weed Wrench loan programs...does anyone know if there is anything like that in the Knoxville area?
