Average Height Of Bonsai Trees

Bonsai trees originated in Japan, but you can transform different types of trees into bonsai trees. Growing a Bonsai tree and caring for this plant style requires patience, dedication, and specific conditions.

If you wish, try growing a Bonsai tree from seed or Misho. Unlike dwarf trees that are genetically manipulated to be a miniature version of a full-grown plant, bonsai trees are managed, pruned, and coaxed into a desired bonsai form.

The classification of bonsai trees is based on whether the tree is a miniature, medium, or large size. However, determining and categorizing Bonsai trees is more of an art than pure science.

Smaller trees can be transferred from their container and allowed to grow into a larger category. Bonsai trees usually exist in trays and small containers and have unique determiners to classify them. Most Bonsai are either miniature, medium, or large.
