So I planted my hops three years ago and they've done well. I'm planning to move next year (within the same hardiness zone) and I want to take my hops with me. I'm sure whomever buys my house won't want the hops and I don't want to lose them. How do I collect the crown to take it with me? Can I take the whole crown, or do I need to clip rhizomes and start anew next year? Should I dig them up in the fall after the bines die off, or in the late winter, or some other time? How do I store them until planting time? If I can take the whole crown, can I store it or must it be transplanted immediately like transplanting a shrub? Can you offer any other advice on taking hop plants with me when I move?
I just waited until the winter and then dug up the entire rhizome for each plant (they were pretty big, it was a lot of digging). I separated the rhizome from the soil and put them in an open box in the new house's garage. It was cold in there, which I think is pretty key. I left them in my garage for around a month after the move because I didn't have time to plant them and hadn't made a space for it. My cat crapped on them while in the box too, but they started growing right there in the box I had them in-- lack of dirt and all. Like a potato that sprouts in the cupboard. That was 6 months ago. Planted them in the early spring and they're now flowering (see attached photo shot today).
Point being: they're pretty hardy plants. I think you can just dig the crown and go with the "relax, don't worry, have a homebrew" mantra.
Seeing how you have time I think you may want to think about burying a few feet of one bine. That will serve as growth for a good new rhizome. Then you dig it up and trim it into a few pieces for planting multiple plants after you move.
I don't remember all the details but a quick google search will help.
I think this might be easier than trying to dig up and save the entire crown.
There is a nice little self explanatory piece about this at FreshHops to check out.
