Kiryu soil is a type of soil that is widely used in bonsai cultivation, especially for conifers such as pines and junipers. It is a soil extracted from the Kiryu region of Japan, it is a volcanic soil mainly composed of volcanic ash, pumice and peat moss. Like Kanuma soil, it has a very low pH of around 4-5 and is similar in properties and characteristics, such as good drainage and the ability to retain moisture, which is important for bonsai. It also has a high cation exchange capacity, meaning it can hold nutrients and make them available for the plant to absorb.
It is important to note that Kiryu soil is not a substitute for all types of bonsai, as it will change the acidity of the soil if mixed with another type of soil. It is important to match the soil to the plant species and not to overuse it, as it can lead to nutrient deficiencies if not mixed with other soil components.
