Kanuma is a soil with high acidity and therefore particularly suitable for bijv.azalea bonsai. This soil provides good moisture in the pot and does not contain too many nutrients.
Kanuma can be applied unmixed. Bonsai should always lightly fertilize for a healthy growth. If you repot the bonsai can prune up to 30% of the roots. For a good regeneration of the
roots can shorten the process only the older thicker roots.
