before the advent of chemical herbicides, how did farmers keep their fence rows clean? my son wants me to call the co-op to have them come out and spray my fence rows, like all my neighbors. i really don't want to do that, because of all the really cool "weeds" that don't grow anywhere else except in rocky fence rows. i like the creepy crawly and chirping things too. call me silly, but's it's one main reason i live where i do. anyway, i've been clearing them by hand, and as you can imagine, it is a tedious, ongoing, time consuming job. i got to wondering if there is an easier way to do it? anyone know what the old timers did??
