I've these two 'Crimson Queen' Japanese Maples that frame my little Koi pond. One of the two has an unruly growth branch that is crowding out the side walk. The branch is pretty large, say about a double D-size battery in circumferrence. I need to saw it off close to the base of the main trunk. Will this be a good time to do so? I remember reading somewhere that pruning JM during growing season will cause them to secrete saps that could be injurous to the health of the tree.
