To expand on my earlier post: Patience is necessary. I got nothing out from a few rhizomes after 5 weeks. I dug them up and put them in a different part of my yard, thinking that those dry, sad looking sticks may still have life, but had no real expectations. After a few more weeks of no growth, I caved in and ordered crowns from Great Lakes Hops. On a side note, Great Lakes Hops is a fantastic company. Super healthy plants that are shooting up my ropes already.
Anyway, you can probably guess what happened next... Everything I planted, including the dead looking rhizomes, are growing, and growing fast. I made room and planned for 4-5 rhizomes, and am now dealing with 8. Hop rhizomes are much hardier than I imagined.
I'm growing Sterling, Nugget x2, Cascade x2, Mt. Hood, Galena, and Glacier.
