Gardens big or small can be positive influences on mood and health. Whether it is a bountiful vegetable garden, a beautiful flower garden, an herb garden on a windowsill, or a bonsai tree on a desk in an office, the act of caring for another living thing nourishes the mind, body, and soul. Mini or micro gardens have been popular in recent years. They are eye appealing and low maintenance. They often include succulent plants that are slow growing and have low demands for water.
