1. Picking: when Hydrangea is still in the seedling stage, it needs to be picked. Usually wait for it to grow about 15cm, use the sterilized blade to cut off the top part.
2. Remnant flowers: when the plant is finished blooming, it is necessary to trim the remnant flowers from the position under the flower head, so as to make the plant more orderly.
3. Old branch: after several years of growth, the old branch should be cut off about 1 /3 of its length. Only when the old branch is cut off, it will grow more new branches.
4. Miscellaneous branches: there will be many disorderly Cross branches and overlapping branches on the plant. The weak branches that overlap should be cut off and the strong branches should be kept, so that the plant will be more ventilated and better growing.
The pruning of Hydrangea can be carried out in summer and autumn. If weak branches and disordered branches are found during its growth, they need to be cut off as soon as possible to avoid unnecessary nutrients in the basin soil. It should be noted that pruning should not be allowed during budding, that is, around November, this time must not prune the plant.
