How to prune hydrangea
ThehydrangeasHydrangea macrophyllathey are pruned between February and March. With thehydrangea pruningit is necessary to completely eliminate all weak branches, dry branches and malformed ones. Furthermore, even the branches that are growing in the wrong direction (towards the inside of the shrub) must be cut, the dried inflorescences must also be pruned by cutting the penultimate pair of buds above. In summary, here are the branches to be cut:
- Weak branches, dead branches, broken branches and malformed branches
- Branches that are growing facing the inside of the shrub
- All dried inflorescences
In thehydrangeascultivated for at least 5-6 years, they must be eliminated to the extent of about one third, all the oldest stems by cutting them at the level of the stump or a little higher. This operation is necessary to thin out the bush, so that more light and air can circulate inside. Thanks to this thinning it will be possible to protect the plant from parasitic attacks and stimulate it to emit new branches that will bloom in the following years.
It is precisely on the new branches that the subsequent inflorescences will develop, which is why thehydrangea pruningleaves unchanged the "young" branches (grown the previous year) and the branches that bear the terminal bud that will give rise to a flower.
