Thanks for the help guys and sorry for the delayed reply. Pretty much I dug some sections out (about 3'x3') of the ground and replaced the clay-ish dirt with good soil, manure, and sand. In each section I placed 2 rhizomes next to each other. So far most of them have sprouted.
In the sections where 2 have sprouted, do you think it's best to go 'dirtyoldducks' method and just use one shoot per plant? Or just stick with one plant to keep things consistent and not overcrowd? I feel like the first method would be a good way to go, but at the end of the day you have 2 plants within inches of each other and according to all of the manuals they are supposed to be 3 ft apart.
This is my first crack at this so just trying to do it right.
