After the seedlings are planted, in order to promote them to have more branches and developed roots, they should be slightly chopped.
In the early spring of next year, the weight will be short, so that it will send out 3 ~ 5 robust 1 annual branches.
During the growth period, we should properly pick the core and cut the tip.
After flowering, the strong branches in shrubs are often picked and cut off, so it is necessary to pay attention to leaving external buds after cutting to facilitate ventilation and light transmission inside shrubs.
Make it have more secondary branches to increase the flowering in the coming year.
The oversized thick branches in the cluster should be retracted and pruned in time, that is, they should be drained from the ground to urge the annual new branches to fill the gap.
In winter, crowded branches, useless branches, withered branches, etc. If it is too dense, it should be trimmed moderately to avoid pruning in summer, otherwise it will reduce the production of flower buds.
