Kanuma 6 to 12 mm - Substrate Bonsai - 17 Lt

The caliber of 6 to 12 mm, is used for Bonsai of very large dimensions, essentially at the bottom of the vessel as drainage layer.


From the area Kanuma (land of the azaleas in Japan), has as main characteristic, possessing a P.H. acid and perpetuate this acidity for a long period, (contrary to the peat which is also acidic but will neutralize (alkalinizing with the regas), this characteristic is due to the fact that the Kanuma be acid by thermal demineralization, which reduces its ability to alkalinization, ensuring acidity during the interval between transplants.

This soil is ideal to be used pure (or as a very high percentage in consorciation with other components) in azaleas, rhododendrons and all species that require p. H. Acid.

In limestone zones (as in Southern Portugal), or when water from watering is alkaline, or in species that are not acidophylls like slightly acidic soils (bouganvilea, citrus, etc...), we can add a percentage (10 to 15%) to the mixture of folhosas to facilitate the capture of nutrients avoiding chlorosis (such as the case of fertile chlorosis- iron deficiency).
