Below is a pictorial of the simple grafting technique that I use. If I can interest just one person to give grafting a try I'll be satisfied.
This is a rootstock that I had already planted into a pot to make it easier for me to take pictures of the grafting procedure. First I cut it off several inches above ground level.
Then you wrap the two pieces tightly together with some sort of tape. Many types of tape will work, black electrical tape, plumbers tape, but I use a tape called Parafilm that was originally made for the medical profession. It seals the graft airtight and doesn't need to be taken off like the other tapes I mentioned. It will degrade with time.
