1、 Pruning method
1. Pinching: when Hydrangea is still in the seedling stage, it needs to be pinched. Usually, when it grows about 15cm, cut off the top part with a sterilized blade p>
2. Remnant flowers: after the plant has finished flowering, the remnant flowers need to be trimmed from the position below the flower head, so as to make the plant shape more neat p>
3. Old branch: the old branch that has grown for several years should be cut off about 1 / 3 of its length. Only after the old branch is cut off will it grow more new branches p>
4. Miscellaneous branches: there will be many overlapping branches and overlapping branches with disorderly growth on the plant. The overlapping weak branches should be cut off and the strong branches should be retained, so that the plant will be more ventilated and grow better p>
2、 Pruning time
Pruning Hydrangea can be carried out in summer and autumn. If thin branches and messy branches are found during its growth, they need to be cut off as soon as possible to avoid consuming unnecessary nutrients in the basin soil. It should be noted that pruning should be prohibited during the budding period, that is, around November, and plants must not be pruned at this time p>
