All organic soils have a stock of these vital chemicals; they come from the mineral part of the soil (sands/clays etc) and from dead organic matter (fallen leaves and dead plant matter).
All Inorganic?
Using only stable inorganic components such as lava rock or pumice will create a soil that will last longer than it really needs to last.
Decaying organic material improves the friability and moisture retentiveness of the soil. This organic material is a great source of nutrients for the microorganisms present in the soil and for the trees directly, both as macro and microelements.
Basic or Organic Soil Mix
The basic soil mix for bonsai has, for many years been grit and peat, mixed to a ratio of around 50:50. The peat holds water and nutrients whilst the grit provides drainage and keeps the soil open.

Bonsai soil is primarily a loose, fast-draining mix of components, usually a mixture of coarse sand or gravel, fired clay pellets, and an organic component such as peat or compost.
Many people, myself included, like to use mainly organic fertilizers. Organic fertilizers are slow release and allow the plant somewhat of a continual feeding this way.
In regards to fertilizers, it is best to use organic products and fertilize in the spring, with a mixture of 0-10-10.

Is the purchase of organic soil important to you. How often you should water the tree. If you have your plant outside, think about how much rain fall you get.
An organic liquid fertilizer such as organic seaweed fertilizer is recommended. Chemical fertilizers can be used but they have to be diluted to half the strength so that it does not damage the roots of the juniper bonsai tree.

Flowering and fruiting bonsai need one higher in phosphorus. When you go to a nursery, especially ones into organics, look for products which can supply trace elements. One that I use is Green Sand but others are just as good.
A good mix is 1/3 aggregate (crushed quartz, decomposed granite, or haydite), 1/3 cinder, and 1/3 organic material (bark chips or coir). Particle size should be about 1/8-inch to 1/4-inch in diameter.
