Answer: Pieris japonica can grow 9'-12' tall with a 6'-8' spread. Trying to move a mature specimen calls for careful planning. Loosely tie all of the branches together for ease in handling, then thoroughly soak the soil the night before the planned move. Depending upon your soil type and how long the plant has been in your present location, you'll find most of the roots in a neat mass about 12" - 18" below ground level, about 1 1/2 times as far out as the the diameter of the shrub. Pieris can be transplanted spring, fall, or early winter. Avoid moving plants during the hottest months of summer, or when the ground is frozen.
