I asked a few questions about growing hops in Wisconsin a while back and there seemed to be several interested (or already growing). My OM has hops and wants to plant more, and I'm thinking I could do with less mowing so I'm deciding where I'm going to put my trellises. I'm considering putting in Willamette and Mt. Hood...American hybrids of some European favorites.
Someone mentioned the different challenges presented in different regions of the US (and the world, I suppose)...but I don't know that I'd break everything up into sub-forums based on location. Perhaps some sticky topics would suit that.
