Chemical fertilizers have played an important role in maintaining the productivity and ornamental quality of Chrysanthemum morifolium, but excessive or long-term application may result in nutrient imbalance, soil acidification, nutrient accumulation, and deterioration of soil biological properties. Partial replacement of chemical fertilizers with organic fertilizers provides a potential approach for reducing fertilizer inputs while maintaining crop growth and improving soil fertility. This paper reviews the effects of partial chemical fertilizer replacement with organic fertilizer on the growth of C. morifolium and associated changes in soil fertility. The effects on plant height, leaf area, biomass accumulation, root development, flowering characteristics, and nutrient uptake are first discussed, with particular attention to changes in nitrogen, phosphorus, and potassium utilization. The influence of organic fertilizer substitution on soil organic matter, pH, electrical conductivity, available nutrients, soil structure, and nutrient cycling is then examined. In addition, changes in soil microbial biomass, enzyme activities, and microbial community structure are considered to clarify the biological mechanisms underlying plant-soil interactions. A representative case study is further proposed to compare different fertilizer replacement ratios and evaluate their effects on chrysanthemum growth, nutrient utilization, and soil fertility. Overall, partial substitution of chemical fertilizers with organic fertilizers can provide both nutrient supply and organic matter inputs, thereby improving soil quality while supporting chrysanthemum growth when an appropriate replacement ratio is selected. However, the optimal proportion depends on soil fertility, organic fertilizer characteristics, crop growth stage, and local management conditions. Future studies should integrate long-term field experiments, soil microbial processes, nutrient-use efficiency, and economic and environmental indicators to establish more precise and sustainable fertilization strategies for chrysanthemum production.
