1、 Pruning time

Hydrangea pruning is mainly carried out after flowering. When it is finished, pruning in time and reasonably will make it bloom better the next year. When Hydrangea is blossomed, it is necessary to cut off a section of long branches, as well as small and dense branches. If you are afraid of waste, you can use the trimmed branches for cutting. Pruning during this period of time can not only reduce the excessive loss of nutrients, but also improve the ornamental quality

2、 Precautions

1. Time: Hydrangea is pregnant from September to October. If pruning is necessary, we must avoid this period. In spring, it can also be pruned properly, but the pruning range can not be too large, mainly cutting off some dead and diseased branches

2. Disinfection: the scissors used for pruning must be kept clean. If there are bacteria on it, it will invade the plant through the pruned wound. Before pruning, the scissors need to be disinfected, especially after pruning the diseased branches. After disinfecting the scissors, other branches can be pruned again
