Hops, certainly traditional varieties, are weeds, and grow with vigour. Ideally my fuggles need at least 20 feet to climb up so dwarf like Prima donna are possibly a better option.
Soil treatment is basically lots of sh*t, blood n Bone, plenty of organic matter, a good mulch during the growing season, and water them well.
They spread like stink though I have planted mine in the biggest pot from BnQ that I could get, which I have sunk into the soil . . . which has stopped them escaping so far . . . but they will be going into a raised bed sometime. . . .
APlus do not necessarily have a good reputation on supply, but Deacons Nursery (Sandown Isle of Wight) is an excellent supplier and has a few varieties for sale . . . traditional and dwarf.
I do have a contact in Germany for some of the 'lager' varieties . . . but need to dig it out.
