A witch's broom is a term used to describe an abnormal growth pattern of branches on trees and shrubs. It gets its name from the appearance it gives to the plant, resembling a broom that a witch would traditionally use. The broom-like structure is formed when the tree or shrub experiences genetic mutations or infections. Witch's broom growths can be caused by various factors, including viral or fungal infections, mites, insects, or genetic mutations. These abnormalities can result in a dense cluster of shoots arising from a single point, giving the appearance of a broom. This abnormal growth pattern can be seen in various plant species, including trees such as conifers, fruit trees, and deciduous trees.
