The field grafted seedling trees 90% of the time I do 2-3 grafts, side veneer. I train the tree to have 2-4 branches. As soon as I see 2-4 inches of growth, I remove the tape. I use conventional grafting tape. I use the same tape to tie the graft to the branch. Monitor when they are 10-15 inches and tie again. Remove all other shots, eventually the shoot dies, and the grafts goes on. I never use plastic ties.
