How much room does a single Jerusalem artichoke (AKA sunroot, AKA sunchoke) plant need, given plenty of sun and a semi-arid climate?
I've grown some wild seedlings (from true seeds from Kansas Native Plants), which I just transplanted fairly close, but I plan to split up some tubers a traditional distance when they're mature enough (probably next spring). So, I'll need to know how far to space them.
The seedlings are looking pretty good. I grew lots of them for plenty of genetic diversity.
