Here is one of my 2 plum trees. But are pretty much identical in size and shape, planter the same day 5 years ago. I KNOW this has way too many branches. I want all my fruit trees to be about 9 foot tall. I have no idea as to how to prune this correctly for maximum fruit. Would someone care to save the picture and point to the branches I need to remove this winter? How do I determine which branches are feeders and not fruit bearers?
