Autumn of last year my friend pruned the plants right back down as you're supposed to do after harvest (or what would have been harvest I guess!)
However the roots had grown right out of the bottom of the pot and into the ground. They will probably be very difficult to plant successfully in another location now as the roots would most certainly rip off if I tugged on the pot. I imagine hops were never intended to be grown in pots for the long term so the future is not orange...
I'm stuck as I have no where else to plant hops that will reach for the skies....
When it comes to making organic beer with organic ingredients, hops are usually the 5% "allowed" non-organic element of the final product. Who knows, I might do it next year.....
