I live in northern NJ and planted this tree in early spring.The hole was just as deep and twice as wide as the root ball.I've also put sweet woodruff around the base to about three inches of the trunk along with assorted perennials starting about four feet from the trunk. It was a warm and wet spring followed by a wetter than average early summer.My problem is that after about five weeks I noticed some of the leaves turning their fall colors,a situation that has persisted until now about half the tree is in this state. The tree was a beautiful specimen about five feet high with excellent bloom. I've used no fertilizers or nutrient supplement of any kind and only watered twice weekly. any help will be appriciated.
