How to prune hydrangeas?

In the process of caring for hydrangeas , pruning management is a very important part. It can not only remove diseased and weak branches and reduce the breeding of diseases and pests, but also help to shape the ideal plant shape. So how do you prune hydrangeas ? Let’s learn more about it below.

1. Pruning time

Most hydrangeas are pruned in late August and early September, when the temperature is relatively suitable and they can resume growth better after pruning. However, due to different regions, different seedling conditions, and different flowering times, there are slight differences in the specific pruning times.

2. Pruning method

(1) Flower pruning: After the flowers wither, cut off the flower balls and keep a section of the flower stalk to facilitate the growth of new flower buds. After cutting off the flower bulbs, you should also trim off some flowers and leaves that are yellow or damaged by pests and diseases.

(2) Branch pruning: Prune off branches that are too long, crossed or dry to maintain good ventilation and light conditions. Use sharp pruning tools when pruning to reduce damage to the plant.

(3) Shaping and pruning: Prune off overcrowded branches to make the branches and leaves of the plant evenly distributed. You can also prune off withered leaves and dry branches to keep the plant healthy.

3. Management after pruning

(1) Control light: After pruning hydrangeas, do not move them to a place with too strong light. It is best to keep them in semi-shade or scattered light.

(2) Reduce watering: After pruning hydrangeas, a large number of leaves are cut off, and the plant's demand for water will be reduced. Therefore, after pruning hydrangeas, you must reduce the amount of watering to prevent root rot.

(3) Proper fertilization: After pruning, hydrangeas will grow new buds and leaves, so they need sufficient nutrients. Therefore, it is necessary to replenish fertilizer in time. It is recommended to use fermented organic fertilizers such as chicken, duck and sheep manure, bury it in the soil, a shallow layer will do, and then cover it with soil.

4. Pruning precautions

When pruning hydrangeas, avoid over-pruning to avoid affecting the normal growth of the plant and flowering the following year. At the same time, be careful not to prune in winter to avoid affecting the plant's overwintering.

In general, pruning hydrangeas is a meticulous and patient job. Only by mastering the above methods and precautions can you better complete the pruning work, thereby promoting the healthy growth and abundant flowering of hydrangeas.
