Division (horticulture)
Division in horticulture is a method of asexual plant propagation in which a parent plant is separated into two or more parts that are capable of growing into individual plants.It is most commonly used for herbaceous perennials and plants with structures such as bulbs, clumps, or rhizomes, where each separate plant includes healthy roots and shoots that are necessary for its survival. Division is used to increase plant numbers, improve and rejuvenate plant health, and maintain desirable traits.
