I married into a family that used to grow a lot of hops in the Willamette Valley in Oregon. After my wife's grandfather passed away her grandmother switched into the nursery wholesale shrub business, but her uncle still makes a hoe specifically for hop growers by hand. I have one myself, used it for vegetable and its great. Not trying to get him any business or anything, just thought you guys would appreciate some history and information from a long line of hops growers.
