They are actually a low maintenance tree. Start with digging a good hole and adding compost (organic matter) to the soil. Mulch around the base of the tree, not up against the trunk. Moist, but well drained soil is best. They really don’t need fertilizer and don’t like ones that are heavy in nitrogen. Avoid pruning the first year other than broken branches. Then, if needed, trim the branches when they leaf out in the spring.
