1、 Pruning during growth

Pruning is required during the growth period to ensure more vigorous plant growth. At the beginning of germination in early spring, each plant needs to leave 4-5 branches and short cut at a position of about 40cm, which helps to control the growth height of the plant, weaken the role of the top, and promote the growth of side branches and buds next to the plant, so that the plant can grow more vigorously and luxuriantly and the plant shape is more beautiful, The number of late flowering will also increase

2、 Post flower pruning

After the flowers have failed, it is necessary to remove the broken flowers in time. Some diseased branches or weak branches should be removed, which can reduce the consumption of nutrients, accumulate the remaining nutrients and promote the development of new branches

3、 Pruning and replanting

Generally, 3-year-old flower plants are the most vigorous, and the trend of weakening and decline begins to appear when they are 4-5 years old. The old roots can be turned out in winter, and then the pest branches can be removed and replanted, or the over dense branch planting can ensure the growth in the later stage
