A Glossary/Dictionary of Bonsai Terms

Mizunuke is a term used in bonsai to describe the process of water drainage from the bottom of a pot. It is also known as mizuhake. Mizunuke is important for the health and growth of the bonsai tree, as it allows oxygen to reach the roots after the soil particles dry up. Mizunuke depends on the type and quality of the soil, as well as the size and number of holes in the pot. Poor mizunuke can lead to mizugire, which is the termination of water supply and can cause branches to die or leaves to fall.

Mizusui is a Japanese term that means "living portion" or "live vein" in relation to bonsai. It refers to the living parts of a trunk on shimpaku (Sargent's juniper) and tosho (Japanese needle juniper) trees that have bleached and withered tree tops or branches . Mizusui is important for the health and survival of these trees, as it carries water and nutrients from the roots to the foliage.

Mizuyari is a Japanese word that means watering, the most important process to grow a bonsai tree. Water supply is essential for a bonsai tree that is grown in a limited space of a pot. Many people say it takes three years to attain the watering technique. There is no perfect manual for watering. Growers are required to pay full attention to various aspects, such as the season, weather, temperature, humidity, soil condition, and tree species.

Mochikomi is a Japanese term that refers to the years of cultivation of a bonsai tree in a pot. It indicates the level of care, love and training that a bonsai artist has invested in their creation. Mochikomi is important for the aesthetic and historical value of a bonsai, as well as for its health and vigor. A bonsai with a long mochikomi usually has an elegant and natural appearance that reflects the harmony between nature and art.

Mochikuzusu is a Japanese term that means degrading in relation to bonsai. It refers to a tree that grows too much, peaks out as bonsai, and becomes unable to maintain its tree shape. Mochikuzusu also means that a bonsai tree's shape will deteriorate after branches or other key elements are broken  . This is a phenomenon that bonsai artists try to avoid by careful pruning and wiring.
