Soil composition is one of the most integral elements of growing bonsai trees. Bonsai enthusiasts have for ages, debated on the composition of soil conducive to the plants’ growth. To make things easy, bonsai soil of variable composition is now available in garden centers and bonsai nurseries.
Ready-mixed earth, these compositions are very effective and support healthy growth of bonsai trees. However, though brewing up your own composition can be quite messy, you should acquire enough knowledge about the building materials of the soil for your own benefits. Academe bonsai soil is one such combination that originated in Japan and is made of baked Japanese clay.
A bonsai is a miniature tree that grows on a small area of soil and therefore, the source of nourishment is also limited. So, the tree should be able to acquire the required amount of nutrients, gases and water in order to grow healthily. This is the reason why bonsai soil needs to be rich in minerals and nutrients.
The soil quality has a direct effect on the vigor and health of the tree. So, if you find your bonsai lacking the health and vigor of a normal tree, then it is the soil that needs care. Akadama bonsai soil is a sensible choice in that case to replenish the stunted growth and malnutrition of the tree.
However, there are certain attributes that make a good bonsai soil mix. Firstly, the soil should have a good water retaining capacity. The soil base should hold ample moisture in it to supply the plant with water during the period between watering. The soil should be able to leave out the excess amount of water. Stagnant water should always be drained out immediately.
You should use a soil mix that is not very high on water retention as lack of aeration is liable to building of salts. Akadama bonsai soil composition in this case makes a good option for water holding. The soil should have sufficiently sized air pockets within it to allow the root caps to draw oxygen inside. Proper aeration is important for the proper growth and health of bonsai.
Well-structured, particle based, inorganic soil should be preferred as it allows rapid drainage of water to make way for fresh air to enter the soil structure continuously. Compacted soil usually lacks both structure and hence, poor drainage and aeration. This is potential enough to cause ill-health to the tree and roots resulting in the roots to rot.
Now, bonsai soil composition for different trees differs. For instance, pine and juniper trees require less water, which demands a soil mix that is low on water retention. Alternatively, the fruiting and flowering species of plants need lots of water and should be placed in the soil mix that is high on water retaining. You can also use Akadama bonsai soil depending on the tree you own.
