Hi there, I was wondering if anyone can give me advise on how to graft grapevines. I have a small vineyard about 500 vines growing and I would like to start my own grafting. When is the best time to start grafting grapevines and what techniques to use. I have a grafting gun that I purchased that cuts 3 ways omega, v shape and cleft cut. After grafting do I wax or do I wait for the grafted part to callus and then put it into the soil. Also are there any DVD's that I can buy or any websites I can go to. Any advise is greatly appreciated. Thanks for your time!!
