A bonsai tree can be any tree that is grown in miniature to resemble an aged tree. The more mature a bonsai tree, the more value it has. Bonsai is Japanese for ‘tree in a pot’. However, simply placing a tree in a tiny pot does not make it bonsai. The grower must possess vision and skill to train the tree’s foliage and guide its shape. This is done through pruning the roots to keep the tree small, wiring the branches, and using other techniques to make the bonsai tree take on the look of a mature tree in nature.
