Re: [nafex] Grafting Tape Choices

I use Parafilm because
1) someone recommended it when I started grafting, and I'd previously used it in a lab and knew that I would find it easy to use.
2) We used melted wax at the grafting class I took (we literally picked up the little potted graftling and dipped the graft into a pot of hot wax) and I knew that would be really hard for me to do. (I went so far as to try it once with a brush. Didn't work because the wax cooled too fast, and cleaning the pot and the brush were both troublesome.)
3) I bought a lifetime supply of it years ago (I don't do all that much grafting.)
4) It work.

I use grafting rubber bands to tie up the graft, and then I cover it with parafilm. The rubber bands by themselves don't keep the graft moist enough — I did that experiment. I also tried using masking tape, which some NAFEXers have reported success with, but that didn't work for me. It didn't usually provide enough stability and it never kept the graft moist enough. Maybe my propensity to little twisty twigs when I graft is the issue.

So I have returned to parafilm and rubber bands. The parafilm by itself doesn't provide the physical support the graft needs to hold the pieces together. It might work for a bud graft, but I mostly do twig grafts. I usually remove most of the parafilm and rubber a couple years later, but that's not necessary, the tree will just push them apart. A sprouting bud can easily burst through the parafilm.

My understanding is that the Romans tied their grafts with twine and then slapped some fresh cow manure over the joint to protect it and keep it moist.

I don't think the graft needs to "breath", as witnessed by the success of "dip it in paraffin".
