Bonsai soil, Ref. 2921

Soil to prevent overwatering and drying out of bonsai. Recommended for young bonsais which are particularly demanding of soil moisture. The mix of lava and kiryuzuna gives a very good result in removing excess irrigation water.
When the soil is drying out, the color of the soil changes from dark to light, which allows you to visually assess the watering necessary.
Percentage proportion by capacity:
lava : kiryuzuna : akadama - 33 : 33 : 33
pH 6

Lava is a unique mineral of volcanic origin with high porosity. It contributes to excellent moisture and air exchange in the soil, is indispensable as a drainage. Due to its porosity is a source of macro - and microelements that promote the growth of the root system of plants. It contains iron, magnesium and calcium. Prevents the formation of mold, acidification and formation of lumps in the substrate. Excellent material for bonsai arrangements and growing mosses on the soil surface.

Kiryuzuna is a type of volcanic sand mined in Japan. It contains a large amount of iron oxide, thereby getting rid of chlorosis in plants. This soil has good breathability, porosity, water holding capacity and drainage. It is able to gradually give up nutrients and trace elements. On sale comes in the form of granules of different fractions from 1 to 6 mm. Does not decompose over time. Does not tend to compact the soil and is very stable in structure, pH 6.5 - 6.8, root permeability is good, aeration is excellent.

Akadama is a natural clay mineral mined in Japan. After sieving and firing, it becomes hard. Depending on the water contained in the granules, the color changes from light brown to dark brown, which makes it easy to determine when watering is needed. It is commercially available in granular form, with grain sizes from 1 to 25 mm. The smaller fraction should be removed by sieving before use.  Stable for 2 to 3 years, then it must be replaced. Acadama resists pH variations and soil acidification. Akadama properties differ depending on the fraction, type and firing temperature. It has excellent aeration, porosity, and root permeability. Water and nutrient retention is optimal, pH 6.5- 6.7. Quality irrigation water prolongs the life of acadama.
