Kiryuzuna 2 L - Japanese bonsai substrate

Kiryuzuna is a special Japanese substrate for bonsai, ideal due to its mineral content. Kiryuzuna has a high capacity to maintain nutrients and retain water. It ensures the gradual release of water and at the same time the proper oxygenation of the root system.

Kiryuzuna is a zeolite of Japanese origin that is obtained from mountain sand. It comes from the decomposition of volcanic gravel and has a pH between 6.5 and 6.8. It has a greater weight and breaks down more difficult than Akadama, and depending on the breeder's experience, it can also be used in combinations, such as 70% akadama with 30% kiryuzuna.
