Effects and benefits of Kanuma soil on flowers and plants

Kanuma soil originates from the volcanic area around Kanuma City, Japan. It is a mineral soil formed by the natural deposition of volcanic ash. In terms of origin and formation, Kanuma soil is a mineral planting material very similar to Akadama soil .

The main components of the two are not much different, it's just that Akadama soil has a higher iron content and is therefore red, while Kanuma soil has a higher calcium and aluminum content and is therefore light yellow.

Characteristics of Kanuma Soil

Kanuma soil is a type of soil formed by volcanic ash deposition. Due to its special geological characteristics, the pores inside Kanuma soil are relatively large, showing a distinct layered structure, which makes the particles of Kanuma soil have a certain degree of elasticity.

As the succulent roots grow, they squeeze the surrounding soil particles, which is the main reason for the pulverization of soil particles. After all, the succulent roots are not like human fingers, which can crush the Kanuma soil by pinching , but slowly apply pressure to the Kanuma soil particles.

Effect of Kanuma soil

Due to its loose structure, Kanuma soil can easily adapt to this slow pressure method and will not break up due to the growth of the root system. On the contrary, the harder Akadama soil will be more powdery in the flower pot than Kanuma soil.

Kanuma soil has good air permeability and many tiny holes on the surface of the particles. It is more suitable for some succulent varieties with strong vitality and resistance to barrenness, such as Hime Oborozuki, Onii-Hina, and Kagome .

And during use, the potting soil should be kept dry and not damp. However, Kanuma soil also has its disadvantages, that is, its hardness is low and it is easy to powder over time, so it is necessary to repot the succulents after a period of time.
