In winter, it is necessary to trim the rose properly. In general, the height of 15 cm should be kept. The above branches can be properly pruned, and the pruning range should not be too large. If the plant is relatively small, it can not be pruned in winter. If the plant grows bigger, it can be cut short according to the size of the plant.
Before pruning, attention should be paid to water control, generally when the cultivated soil is slightly dry. When pruning, the dry and dead branches, Cross branches and branches with diseases and insect pests should be cut off. Do not prune the thick branches on the top. They contain sufficient nutrients. Keep about 10-20cm, and the nutrients after pruning will flow back to the bottom, so that new branches can grow. Prune the overlapping branches, generally keep the height of 1-2cm, and cut off one of the overlapping branches.
After pruning the rose, we should pay attention to that the pruned branches should be centralized and discarded, because some disease branches will have pathogens on them. If the disease branches are placed next to the plants, it is easy for the plants to suffer from disease again.
