Proper care of a Bonsai tree requires the right balance of soil, water and regular pruning. Since these miniature trees continue to grow overtime, repotting is required to allow expansion of the root system.
The best soil for bonsai trees has two main attributes. First, the soil must be able to effectively absorb nutrients from the environment. Second, it must not retain too much water. The soil needs to be able to drain without giving up too much moisture.
Bonsai trees survive best when watered once a week. Owners should pour water into the soil until the bubbles cease to rise to the surface. Avoid using pressurized water delivery systems, as they can push the needed soil out of the pot. Additionally, owners should wash the tree's foliage in order to remove dust and increase overall water absorption.
Pruning is important for the Bonsai tree because it redirects the natural growth of the plant. The owner prunes the tree in order to shape it into the chosen style, removing new growth as necessary. Springtime is the ideal time for pruning. In addition to seasonal pruning, most trees require repotting every two to three years. This process encourages more compact root growth and provides the plant with fresh soil.
