How to trim hydrangea

Hydrangea will differentiate into flower buds in autumn. after the flowers are completely lost in June, pruning should be carried out to promote the germination of new branches. in order to make the crown of potted hydrangea beautiful and blossom, it is necessary to prune the plant. let's take a look at the pruning methods of hydrangea flowers.

Pruning of Hydrangea cuttings

Usually, when the new shoot of the cuttings grows to about 15cm, the coring is carried out to promote the germination of new branches in the rhizosphere. Before the new buds germinated in the early spring of the next year, 5-7 strong trunks were retained in each clump, and the thin and unhealthy branches were cut off, so that the nutrition concentrated on the growth of the new trunk and formed buds, which could blossom in the third year, but the branches that were too exuberant to grow should be picked out in time to slow down their growth. After 2-3 years of cultivation, they could be out of the nursery. When they came out, they should bring soil balls to protect the strong buds at the base of the branches.

Pruning of Hydrangea seedlings

For the plants propagated by ramets, after the growth is restored, the non-standard branches should be trimmed first so that they can become high and low plants. If the number of branches in the clump is insufficient, the strong buds of the dry base should be supported in time to make the new plant with 5-7 trunk, and the old branches in the clump should be renewed in the third year to keep the new plant young forever.

Pruning old branches of Hydrangea

Hydrangea usually blossoms on biennial strong branches. after flowering, the old branches should be cut short and 2-3 buds should be retained to limit the plant growth and promote the growth of new shoots. Cut off the top of the new shoots after autumn to stop the branches from growing so as to survive the winter. After such pruning, the plant type is more beautiful, which greatly enhances the ornamental value.

Hydrangea turns over to change soil

Potted hydrangea flowers usually turn the pot and change the soil once a year. It is appropriate to turn the basin and change the soil in the first ten days of March. The new soil was prepared with 4 parts of foliage soil, 4 parts of garden soil and 2 parts of sand, and then an appropriate amount of rotten cake fertilizer was added as base fertilizer. When changing, it is necessary to prune the roots of the plant, cutting off rotten roots, rotten roots and overlong roots. After the plant is moved into the new pot, the soil should be compacted, watered and placed in a shaded place for about 10 days, and then moved outside for normal management.
