Great job on your grafting! I only have 1 success out of 5 attempts. I grafted to create a rainbow tree but recent bouts of rains rotted my graft unions.
Once you graft the plant the intention is to keep it permanent. Like Scott Pratt is hard to root so it makes sense to graft it but once the graft is established you leave it to mature into a full grafted tree but you won't cut it to root it, since it defeats the purpose of grafting.
If you had grafted the Scott Pratt on only one branch of the Celadine and left the other Celadine branch, you could have had a 2 colored plummies (red on one branch and yellow on the other) and that is a space saver in itself. Hope this helps a little bit.
