Grafting with Hybrids?
First off, I'm skeptical about this latest grafting "buzz." For the home gardener, I suspect it's a waste of money. But that said, It seems to me that the best case is promoting grafted plants to increase the yield (and perhaps disease resistance) of heirlooms. (?)
But grafting stock seed is very expensive, and grafted plants are really expensive. So here is the question -- has anyone tried grafting to a vigorous (regular) hybrid? It might produce decent results from a much lower cost. Or, there might be a few OP varieties that could be used as grafting stock effectively?
