We have been trying to stay ahead of the weeds this year, as it did not freeze here this year.  I had been crawling along ripping them up by hand.  That works if you only have a few rows but now we have too many.  I had to modernize.  I discovered a  tool in my barn, its called a hoe, that I had not touched in many years (how long has it been since you hoed a row of beans?).  I think ancient man discovered this a long time ago but it works great form me now!
