I am not experianced in grafting at all, but I have 6 different apple trees on my place in an effort to get different drop times. I was thinking that it may be in my best interest to mix these varieties via grafting. Is this a good idea? What is the best method of graftingfor a rookie like me to try? Trees where 3 gallon box store specials and have been in the grond now for 2 years - some tried to produce fruit last summer -I stoped them as the tree would not have been strong enough to support fruit and I wanted the tree to focus on physical growth.
