I actually find them trouble free once established. I mulch, prune, and feed in spring and feed a couple times over the summer and harvest when ready. I would think ripping them out and dismantling the trellises would be more work than its worth given that they are attractive plants even if you didn't bother harvesting.
Yeah, growing them is easy. It was the processing and packaging I hated. I'd get up to 25 lb. from a single plant and it was just to much hassle. And I didn't trellis..just grew them up a deer fence and across the top.
I actually like this part. There is nothing like a fine September day, coming home tired from grouse hunting, to go snip and take down the vines, then sit back in a lawn chair, pouring myself a homebrew, and sit there mindlessly picking hops. Hey, I am sitting around outside drinking beer and doing something!
Processing is easy. I just put the plastic tub with the hops into my garage, turn them over by hand for a couple of days, then vacuum seal them up.
What I dislike are all the people I know who grow hops, who don't brew, and want to give me their hops. People will give me ziplocs full of old yellow hops past their prime, that I know spent a good deal of time picking them. No! I don't want your hops, the hops you don't even know what variety they are! I grow all the hops I need, and order the rest!
