I bought some hop rhizomes/roots from a lady on craigslist. She said they are 3 years old and were taking over her garden. The ones I've seen for sale are nice tidy little stick looking things. What I purchased is a big mangled mess. My question is what do I do with them? Should I just plant the big mangled mess? Or can I cut the big thick pieces into smaller pieces (6# or so) and plant each piece in an orderly fashion?
