Aluminum Foil is used to shade out in case the sunlight gets too intense in the afternoon. Only the south side of the graft is shielded. Notice that the union is not covered with aluminum, only the upper scionwood. The scionwood that I used on this one is non-dormant. You can use non-dormant wood any time too, provided you keep the scionwood alive during transport in a cooled container, and then when you graft them, you will have to shield them from overheating, and one of the quickest way to do that is to use aluminum foil. Shown here is a non-dormant scionwood that I grafted.
