This weekend I did a little summer grafting - my first time. I was a lot more conservative this time, only making 20 grafts. 15 are on Acer palmatum rootsock, and 5 are on Acer pseudosiebolianum rootstock (hardy to Zone 4). So this small lot is an experiment on several levels. Here's where I find myself confused. Winter grafting seems to be extremely straight forward - cut dormant scion, graft onto rootstock, keep humid and wait. Summer grafting seems to be all over the map in comparison. Some say to graft onto understock and leave the understock growing, others say to cut the understock completely off at the graft. Some say to remove the leaves and petioles, others say to leave the petioles, and sill others say to remove all but 2 leaves. In lieu of any definitive documentation, I put together the best ideas for me and did the grafts (see pics) as best I could. I did them pretty much the same was as winter grafts, but I left the petioles on the stems, and I used Parafilm this time in addition to the grafting strips. I cranked up the air conditioning in the Studio, and everything is nice and cool. So now my question is this - do I need to place bags over the scions, or is Parafilm enough? Am I botching this big time? Something I overlooked? I need the opinions of those who know... Thanks!
