The invention belongs to the technical field of Chinese rose planting, and relates to a planting method for improving potting Chinese roses with a controlled-release compound fertilizer. The plantingmethod includes the following steps that preparing before transplanting is conducted; substrates enter pots; Chinese roses are transplanted into the pots; potting management is conducted; Chinese roses are bloomed. A soilless culture technology is adopted, the controlled-release compound fertilizer is applied for planting the potting Chinese roses, the soilless substrates are prepared from grass carbon and perlite in proportion, matrix gaps are suitably increased, air flowing is facilitated, growth of roots is unhampered, and nutrients in the substrates can be absorbed; the controlled-releasecompound fertilizer is applied, the releasing rule of the nutrients and the rule of nutrients required by growth of the potting Chinese roses are basically same, nutrients can be stably provided at all growth stages of the potting Chinese roses, and the quality of the potting Chinese roses is guaranteed. Compared with soilless-substrate potting Chinese roses without a controlled-release compound fertilizer, the increasing rates of the plant height, the stem thickness, the branching number, the flower diameter and the petal number of the potting Chinese roses can be 38%, 17.8%, 20.3%, 27.5% and30.2% respectively.
