great post, Jonas. please clarify the handling of the plastic bags. what I think (but not sure) is that the bags are normally open at one end, and you cut apart one side to facilitate wrapping around the scion. how far do you cut open the side?… all the way? then the open end of the bag is wrapped/sealed with the grafting tape, and the blue tape is used to seal the cut side of the bag. sorry for this long post. thank you.
The bags are cut just as far as the photo shows – the blue tape is to shade the scion. I typically graft toward the end of winter/early spring, though it can be done later as well.
When is a good time to do grafting, Jonas?
As a replacement for the bag & sphagnum could the parafilm be extended over the foliage to act as a moisture retaining cocoon?
Hi Paul – yes, parafilm can be used instead of bags. I haven’t tried it myself but would like to as it’s a fast and easy technique.
