I have a couple of 2-year-old muscadine vines ordered from Ison's. One is Ison, one is Darlene.
I wondered about grafting other varieties onto these vines in cocktail-style, where maybe I aim to change half of each vine to another variety, thereby having 4 varieties instead of 2.
But I know nothing about grafting grapes. I tried googling grafting muscadines but everything i found was talking about propagation of entire plants, not "cocktail" grafting.
Anyone know anything about this or have any cuttings to share?
