innoculation and apios americana
I am growing a groundnut, also called Apios Americana. It's a legume native to the US, and can be harvested both for peas and for tubers. This is my first time growing it, and it is said that the peas within the pods are edible just like typical garden peas. This year I did nothing special to prepare the soil (it's in a container right now). It's been growing since may and is now a tangled mess and I can see flowers stalks forming.
Since the tubers are the main harvest of this plant, I am wondering what innoculation might do to it. Since the tubers are just a swollen portion of the root, can I expect it to get knotty and weird looking if I innoculate? Would this be ok to eat even if that were the case?
I realize this plant is an unkown to almost everybody, but any help is appreciated.
