The characteristics of potted landscape fertilization are less quantity and longer efficiency. Generally, slow-release organic fertilizers such as bone meal and cake fertilizer are used as the main body, which are compounded with slow-release urea formaldehyde, phosphate rock powder and a small amount of quick acting fertilizer.
If there is no ready-made special fertilizer for bonsai, it can be treated with olive oil or plastic film wrapping solution by using the commercial flower fertilizer roller, which can achieve a sustained and long-term effect. The fertilizer can be shallow buried in the substrate beside the basin.
