Transplanting, in its general definition, is the operation of taking a plant up from the soil and planting it again in a new location, where it is expected to continue normal growth. The term "plant" is applied to trees, shrubs, vines, perennials, and annuals. Correct transplanting implies that a plant in its new position should be left in proper posture, and firmly imbedded in good soil. In addition to placing plants in new and permanent locations to have them more effective, or where they may develop to better advantage, it is often necessary to move plants from masses in order to prevent crowding and to provide more space for the remaining plants to develop. This is true especially with nursery-grown stock, and in plantations also which are made dense at the outset in order to produce an immediate effect.
