Yesterday I received the scion from CCCP. I ordered Xie Shan, USDA 88-2, and Boukhobza. I used mostly T-bud on my Carizzo rootstock in a pot. Very easy to lift the bark this time of the year. I did a couple of cleft grafts but the budwood is too small so I don't think they will take. So after budding and wrapped with buddy tape, do I need to cover the graft union with alumninum foil and keep it under shade?
