This study systematically explores the importance, principles, specific methods, and supporting precautions of pruning techniques for ornamental peonies. The pruning of ornamental peonies must follow 4 core principles: balanced growth coordination, ventilation and light penetration, disease and pest prevention, and aesthetic shaping. Pruning is mainly carried out in spring and autumn. In spring, it is conducted before flower bud germination, with core operations including cutting off suckers, thinning flowers and buds, and removing withered flowers. In autumn, it is implemented after leaf fall, focusing on operations such as stub cutting, main branch determination, selection and retention of flowering branches, and removal of diseased, weak branches and abnormal buds. Based on this, this paper proposes a coordinated pruning model consisting of the “three cuttings and one determination” in spring (cutting suckers, thinning flower buds, removing withered flowers, and determining main branches) and the “three removals and two cuttings” in autumn (clearing diseased and weak branches, clearing crossing branches, clearing abnormal buds, cutting unlignified shoots, and cutting redundant flowering branches). Additionally, key supporting management points are clarified, including tool selection and disinfection, water and fertilizer management after pruning, and regular plant monitoring and maintenance. This technical system can provide technical support for the standardized shaping of ornamental peony plant type, precise regulation of flowering period, and sustainable cultivation management, and has important practical value for improving landscape effects and extending the peony industry chain.
