Under normal conditions of cloudy days and good mulch-ing protection to prevent later evaporation perennials can be trans-planted during their growing period, except when they are nearingtheir maximum of growth and blooming condition. It is preferable,however, to transplant perennials as soon as their maximum growth iscompleted for the season, and at the time when the newly transplantedmaterial can obtain a slight root growth in its new location beforewinter conditions commence. There are some types of perennials, asindicated in group No. XL-A, Page 289, which should be transplantedin the fall, and others which should be transplanted in the spring.For most perennial stock, however, there is no difference between fallplanting and spring planting, provided the proper time is selected ateither season. The principal objection to transplanting perennials inthe fall is that in heavy clay soils and in the colder climates the plants,if not carefully mulched during the winter months, are apt to beheaved from their new locations by freezing and thawing.
