1. Pruning method
Pruning the old stumps of Chimonanthus praecox mainly involves pruning branches, cutting off the excessively long branches and leaves on the plants, and cutting off the old dead branches in the crown. In the process of propagation, we should pay attention to whether there are diseased branches and weak branches in the plant, and need to cut them off in time. Pruning plants is beneficial to reduce the loss of nutrients and make the remaining branches absorb nutrients better.
Pruning after flowering
Chimonanthus praecox generally forms flower buds every other year, and new flower buds usually grow on new branches. Therefore, it is necessary to cut off the old branches that have blossomed in time, and the pruning time is chosen after flowering, which is conducive to reducing the loss of nutrients and promoting the growth of new branches.
Pruning time
Pruning time of Chimonanthus praecox is generally from March to June, that is, after Chimonanthus praecox period. Pruning Chimonanthus praecox in July is not recommended, which is not conducive to the flowering and growth of plants. Old piles need to be trimmed every winter, just lightly.
4. Preventive measures
In the early stage of growth, the flower heart of Chimonanthus praecox needs to be germinated and picked. When the leaf buds of Chimonanthus praecox germinate about 5 cm, it is necessary to erase the redundant buds that are dense, introverted and close to the ground. In the vigorous growth period, when the branches and leaves grow to more than 40 cm, it is necessary to remove the heart and promote branching.
