All things being equal, I would rather plant my hops in the ground. However, due to constraints with renting a duplex, having a typical garden isn't feasible. I have 4 planters right now and they are approximately 10-12" in diameter. The hops are growing fine, but clearly I need to work out a more permanent place for them. What could I use as a trellis replacement? Here are a couple of pics of what I have going on right now. Also, since this is my first time planting hops, what can I expect in terms of yield? Do I need to replant them every spring or will the roots keep during the winter?
