I have very recently attempted my first lot of grafting and it is a case of trial and error as I am experimenting and learning the art of grafting. It appears that most people graft on 1 1/2 - 2-year-old understock that is seed grown; I on the other hand am attempting to graft to cuttings struck less than 1 year ago. The cuttings I have used don't have a great root system yet, but the roots are substantial enough to keep the plants looking healthy. I have also read that most people graft to understock that is the diameter of a pencil but the understock I have used isn't anywhere near the thickness of a pencil. As I said before it is all one big experiment! If I have success it could effectively cut down the time frame for producing successful grafted maples. I guess if I can get the grafts to take the next couple of years will prove whether the plants will survive and grow strong. For an example of the diameter of the understock I have attempted to graft to check out the letter 'O' on your keyboard! It will either work or it won't I suppose time will tell. I will post some photos when I get an opportunity to take some. It appears that 2 grafts that I did 5 weeks ago (my first ever grafting attempts I might add) appear to be melding together well. It is winter here in Sydney Australia and apparently still really too early to graft. But again I am learning and experimenting:). Has anyone had any success or experimented the way I am? If I have success I will post pictures! If I don't I will use the tried and tested methods of grafting outlined in this forum.
