In the past few weeks some of my local grocery stores have been receiving an influx of table grapes. I have found a few varieties that have some exceptionally great flavor. Black Corinth, red grapes, and some green grapes. Is there any possibility that a grape bunch (of course after you picked all the grapes off of it) could root? I currently have a semi-sterilized bare grape bunch in a small container of distilled water and honey solution. The grape bunch stem was dipped in Garden Safe Rooting Hormone before being placed in the water and honey solution. There was a decent piece of the peduncle and cane (shoot) still attached to the grape bunch. I have experience with cloning tomato plants, peppers, and even pumpkins, but grapes seem to be a new challenge for me. I also thought about using some gibberellic acid as a rooting hormone. But at about $25-$50 per gram, well that could get quite expensive. Why am I doing this you may ask, well the grape vines are not available for purchase.
Please let me know if this is possible. Or if there is another way I should attempt this experiment.
