A tree planted in a small pot is not a bonsai until it has been pruned, shaped, and trained into the desired shape. Bonsai are kept small by careful control of the plant's growing conditions. Only branches important to the bonsai's overall design are allowed to remain and unwanted growth is pruned away. Roots are confined to a pot and are periodically clipped. Bonsai may have a stylized or an exaggerated form ... but, as found in nature. The appearance of old age of a plant is much prized and bonsai may live to be hundreds of years old. The living bonsai will change from season to season and from year to year requiring pruning and training throughout it's lifetime ... and as time goes on it will become more and more beautiful.
