Harvey, I have done a lot of reading on the topic also, and still am in doubt as to what is the proper way of doing. Understanding how the tree grows seems to the the only thing that makes sense. I am thinking that having enought branches for an everyother year (rotating) is the way to go, so, branches you cut this year, will sprout again and will fruit next year. the ones you cut next year will produce the following year, so it is like have 2 trees in one. I am thinking that puting some ribbons on the branches to trim in 2013 and every other odd year. However, the literature also says to cut every skinny little branches.. well you and I know those are fruiting branches..I have done enough wrong to my tree, it is like starting over now with new grafts. if you decide to trim the panache.. I am desiring some of those!!!! (trade perhaps?)
