I have a young Seckel pear that I planted bare root in the fall. I headed off the whip at about 30". It was given no fertilizer or compost etc., but just planted in about a 3' diameter area cleared off sod and mulched with straw. The tree has started to grow well now, but I am not clear what to do in regard to training it. It has sent up from near the top three almost vertical leaders each about 15" high now. I know that if I do nothing, it will end up like my neighbor's pear- 20' high and very vertical -- which I do not want. (I was aiming at more like a maximum height of about 12'). Any recommendations as to what I should I do. Anything this summer or should I wait till winter? Should I be using spreaders or the like early on?
