The broom style, or Hokidachi, is a type of bonsai that mimics the shape of a deciduous tree with a straight and upright trunk that branches out evenly in all directions. The branches are fine and dense, forming a rounded crown of foliage that resembles a fan or an umbrella. The broom style is suitable for species with small leaves and flexible twigs, such as elms, maples, and zelkovas. The trunk should not extend beyond the lower third of the tree, and the crown should cover the upper two thirds. The broom style is one of the most elegant and refined forms of bonsai, and it requires careful pruning and wiring to maintain its symmetry and balance.
