Selecting the appropriate soil in which to grow bonsai trees is an important factor in achieving the healthy development of a bonsai plant. Since a bonsai plant undergoes a special process to stay miniature, the area or the place in which it grows is also different from that of ordinary trees.
Bonsai soil plays a very important role in providing the bonsai plant’s basic survival needs, which are moisture and nutrients. Quality soil for bonsai plants should be able to hold enough amounts of moisture and nutrients. It should be mixed often and appropriately to maintain good air circulation for the roots and proper water drainage. Mixed soils which can be purchased in gardening tool shops are usually expensive; bonsai planters will be able to save costs by deciding to make their own bonsai soil.
There are two basic required qualities for a good soil mix for bonsai plants. The first is that the bonsai soil must have good water-retaining and nutrition-absorbing capacities. Second, a good soil mix should be able to drain water effectively. The soil must not only allow air to penetrate the compost which is required by the plant, but it must also enable excess water to drain immediately from the pot to prevent the plant’s roots from rotting.
There is no single soil mix that best serves the cultivation of all bonsai plants. Variables such as rainfall, local climate, watering routines, and tree species also contribute to factors that influence which soil mixes will be ideal for your particular plant.
