1、 Early spring pruning

In the early spring of each year, the first pruning shall be carried out before the branches germinate. At this time, the weak branches, repeated branches and diseased branches shall be cut off to reduce the loss of nutrients and be more conducive to the growth of new branches. In addition, at this time, it is best to turn the soil once and clean up the weeds in the basin soil to make the plants grow better

2、 Post flower pruning

Cut off the remaining flowers in time after each flowering. Keeping them will not only affect the beauty, but also continue to consume nutrients. When pruning, in addition to the residual flowers, the two compound leaves under the flowers should be cut off to avoid sprouting weak twigs, otherwise the flowers will be deformed. Or cut off the flowers ten centimeters away from the root system, and cut off the redundant branches together, so as to save nutrients and make new buds germinate

3、 Lateral bud pruning

During flowering, it will be found that there are multiple flower buds on some branches. At this time, don't be reluctant. Cut off the bad ones in time, leaving only the good ones. Just leave two or three new buds on each main branch, and cut off the superfluous ones. In addition, the redundant side buds should be cut off, leaving only one main bud to avoid unnecessary nutrient consumption
