Many trees set out are dead or are doomed to death before they reach the plant hole. Transplanting a tree from one site to another is a surgical operation during which the patient needs special attention. It is rarely, if at all, possible to take up all the fine rootlets with their root-hairs intact; these adhere closely to the soil particles, hence in the attempt to remove them a portion of the feeding apparatus is always mechanically destroyed. Next, the delicate root-hairs and fibrils are apt to dry out when exposed to the air, especially in windy, sunny, dry weather, and thus another portion of the feeding apparatus is lost; lastly, with larger specimens, the far-lying roots can practically not be reached and a third portion of the root system is cut off. Furthermore, if the plant material is shipped any distance, the vital activities are interrupted, temperature and moisture conditions may be unfavorable during transshipment and a partial drying out of roots, buds, or foliage is the consequence. As a result of these losses the balance between crown and root, between consumption and supply of water, is disturbed, and, unless this balance is at once reestablished by pruning at the top and by favorable conditions for replacement of lost parts at the root, a part of the crown must die. This trouble may be nearly or entirely avoided by transplanting with a ball of earth, when the root system is not at all ...« less
