Any good tips for pruning these things. THis tree is about 5 years old and grows like a bad weed and never produces even though it flowers up. Previous years i would just top it and trim the sides and the thing is so thick even if it did produce you would not be able to to get anything off it. This year since it did not produce i once again topped and trimmed it and then started to take allot of branches out of it thinning it out, will hit it again at the end of the season. One of the problems im seeing is from topping it the ends of the tops keep branching out making the top extremely thick. Yes i know this was the wrong time of year to do a trim but figured its not producing so why not.
