How to prune hydrangeas

Hydrangea , also known as hydrangea, is favored by many flower lovers for its fairy-like large spherical flowers and rich colors. Whether planted as a potted plant or in the ground, hydrangeas can add infinite vitality to the environment with their lush branches and leaves and beautiful flowers. Let’s learn how to prune hydrangeas.

1. The importance of pruning

Regular pruning is particularly important for potted hydrangeas. Plants that have not been pruned for a long time are prone to lignification of old branches, affecting the germination and flowering of new branches.

2. Pruning tips

Initial pruning: For seedlings that have survived from cuttings, top and pinch the new branches when they grow to about 15 cm after being potted to promote branch growth.

Branch pinching: When the branches grow to a certain length, perform a second pinching to grow more side buds and branches. Note that pinching should not be done after September to avoid affecting the differentiation of flower buds.

Pruning after flowering: After the flowers fade, cut off the remaining flowers in time and pinch the tips appropriately to promote the growth of new branches. At the same time, cut off the dead branches, diseased branches and weak branches at the bottom, and keep the strong main branches.

3. The effect of pruning

Through continuous pruning, the hydrangea plant will become fuller and more compact, the number of flowers will increase, the flower balls will become larger, and the color will be brighter.

4. Maintenance of hydrangea

The maintenance of hydrangea is relatively simple, but you need to pay attention to the good air permeability of the soil. It likes acidic soil and you can add fermented pine needle soil in an appropriate amount. It should be placed in a place with sufficient light throughout the year. Use multi-element or high-nitrogen fertilizers during the growing season, and switch to phosphorus and potassium fertilizers before flowering. When watering, keep the soil slightly moist to avoid water accumulation, and the pot used should not be too large.

In short, timely pruning every year can not only promote the healthy growth of the plants, but also make the hydrangea flowers more luxuriant.
