Special features and instructions of use : 
Stimulation of bonsai after the winter by raising the nitrogen rate (N) to optimize the growing season. This fertilizer is a supplement which vitalizes the bonsai trees over a short period. It must be used in addition to a basic fertilizer.
The special composition for bonsai is designed to act quickly and meet spring demands without breaking the cultural balance. The perfect combination of nutrients strengthens the resistance and stimulates a good development. Thanks to the diversity of organic material, it is perfectly assimilable and available for all species of bonsai. It boosts the microbial life of the soil for a better assimilation of the nutrients.

Mizu-haru provides a complete, quick, progressive and sustainable nutrition. It respects the growth rate of the bonsai, while improving the quality of its soil by acting directly on the microbial life. Thus Mizu-haru guarantees a regular nutrient release which, combined with the absorbent capacity Akadama, greatly reduces leaching losses occurring when the plant is regularly watered.
