Rose pruning is divided into growth pruning and dormancy pruning. (1) Pruning in growth period. After the flowers wither, the residual flowers should be cut off in time and the diseased branches and twigs should be thinned to reduce nutrient consumption and promote the development of new branches. (2) Pruning during dormancy. Before germination in early spring, each plant should have 4-5 branches, and the branches should be cut off at 40 cm-50 cm from the ground. Each branch should have 1-2 side branches, and each side branch should have two short buds. Roses can live for more than 20 years. The flowering of 3-year-old plants is the most vigorous, and it begins to decline after 4-5 years, and the yield and quality of flowers decline. Therefore, it needs to be updated and rejuvenated. The method is as follows: in the rose garden that has been planted for 4-5 years, dig out the old roots in winter, remove the branches of pests and diseases, then replant, divide the plants that are too dense and lush, or cut off the aged rose plants on the ground in autumn and winter, then plough the soil between the rows of roses, apply cake fertilizer and fill them with water. In this way, although there are not many flowers in the second year, the flower output will be greatly improved in the next 2 ~ 3 years.
