Division (horticulture)

Division, in horticulture and gardening, is a method of asexual plant propagation, where the plant (usually an herbaceous perennial) is broken up into two or more parts. Each part has an intact root and crown. The technique is of ancient origin, and has long been used to propagate bulbs such as garlic and saffron. Another type of division is though a plant tissue culture. In this method the meristem (a type of plant tissue) is divided.
