I live in the Catskills, zone 5, and there were several wild grape vines on the property when I moved in. Up till now I have simply clipped them back and used the vines for decorative wreaths, because the grapes are horrendously tart.
What I was wondering is whether it is possible, by feeding and nurture, to make them produce more palatable fruit? I also have 6 apple trees which had been untended so long they were nearly crabbed. Six years of feeding and care have brought them back to nearly perfect producers (I am strictly organic and don't mind a little discoloration on my apples - they taste great!).
I realize the cases are different - the apple trees always had the capability of producing large luscious fruit with proper care. I don't particularly *need* the grapes or I would buy a few cultivated vines, I'm just curious. Can wild grapes be persuaded to do the same, or should I forget it and just keep harvesting the vines for crafts?
Thanks, Sylvia
