The planting season for evergreens begins later in the spring and earlier in the fall than the corresponding seasons for deciduous plants. The reason is that the majority of evergreens will not survive the shock of transplanting in the spring unless the soil is "warm," i. e., the condition of the soil must be such that immediate root growth is stimulated, and in the fall root growth must be continued to insure a development of new feeding roots before cold weather and soil produce dormant conditions.
