Was a question that popped into my head with ideas to grow some a little easier in the dessert. Back a few years they posted about grafting to a potato stock, and similar to growing tomatoes, I questioned such for a palnt myself, but am also interested into the interactions. (A batch of smashed potatoes without the nasty flavor of RSO sounds awesome.)A multi mother grafted together strikes me as a risky, eggs in one basket approach to keeping a collection. If that one plant gets sick and dies, you lose everything. I think sharing clones is the best way to preserve mothers you aren’t working with and have no immediate plans for. Just give 3 reliable growers the mother and any babies and don’t worry.
