Division, in horticulture and gardening, is a method of asexual plant propagation, where the plant (usually an herbaceous perennial)[1] is broken up into two or more parts. Each part has an intact root and crown.[2] 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.
