Naruko Fertiliser Slow Release Bonsai Feed Gentle 5-5-5 formula Breaks down slowly over time to avoid risks associated with over-feeding bonsai. Naruko is natural and chemical-free. Place a small amount of the granules onto the surface of the soil. It will gradually wash into the soil each time you water. Apply more when granules disappear. We use three applications per year on outdoor trees, in April, June and August. This fertiliser is used extensively by Japanese bonsai nurseries. We import this in large sacks and decant it into grip seal bags for ease of use. If you have any questions or would like any help or advice please contact us by clicking here.
