The invention discloses a novel method for preparing greening waste compost, which converts the greening waste compost into stable and harmless organic fertilizer suitable for soil fertility through decomposition and fermentation, improves the structure and physicochemical properties of soil, increases the content of organic matters in the soil, and improves the soil fertility. The method sequentially comprises the following steps: S1, uniformly mixing greening wastes with sludge, soil, urea and an additive according to a ratio; s2, uniformly mixing, stacking, and controlling the temperature and the humidity; s3, fully fermenting, and detecting various indexes to obtain a fertilizer; s4, returning to fields and forests. The process steps are simple and easy to operate, the organic fertilizer which is stable, harmless and suitable for soil fertility is converted through decomposition, fermentation and the like, the structure and physicochemical properties of soil can be better improved, the content of organic
