A pre-bonsai is a young plant that is being grown and shaped to become a bonsai in the future. It is not yet in its final form or pot, but it has some characteristics of a bonsai, such as a smaller stature and root system. A pre-bonsai can be grown from a seed, cutting, or nursery stock, or collected from the wild. A pre-bonsai requires regular pruning and training to develop the desired style and appearance of a mature bonsai. A pre-bonsai becomes a bonsai when it reaches a stage of refinement and shows an artful miniature replica of a full-grown tree in nature.
