Why doesn't hydrangea blossom?

Hydrangea, also known as eight Immortals, Ziyang Flower, its flowers are large and full. The color is changeable, the ornamental value is extremely high, and summer is its open season, but the breeding friends found that their hydrangea did not blossom, what happened at this time? Let's have a look with the editor.

1. The condition of flowering is not reached.

Generally speaking, hydrangea is an old flower, because the bouquet of hydrangea is so large that the new twigs cannot support the bouquet, so there is not enough strength to prop up the bouquet until the branches are ripe. If it is a newly bought seedling, if it could not blossom at that time, you should take good care of it and wait until the next year to blossom.

2. Improper lighting

Hydrangea is a short sunshine, which needs to be kept without light for more than 10 hours every day, and the flower bud can be formed after about 6 weeks. if it is in an environment with sufficient light for a long time, it will not blossom. If you want it to blossom, you should first cool it for 6-8 weeks, and then put it in an environment of about 20 degrees. When the visible inflorescence is, you can lower the temperature by about 16 degrees, so that it can blossom for 2 weeks.

3. Improper watering

When watering hydrangeas, it is not appropriate to pour water on the leaves, especially those that have budded and bloomed. If you pour water on them, the buds will fall off and cause flowering failure. Therefore, when watering hydrangeas, you should pay attention to it. It is best to water slowly along the edge of the basin until water leaks out from the bottom of the basin.

4. Improper pruning

Hydrangea needs to be pruned in time in the process of breeding, if it is not pruned, it is also very easy to cause it not to blossom. Generally, it is necessary to cut off the ends of the branches in time after the flowers are shedding, so as to promote the division of new branches. When the new branch grows to about 10 cm, it is treated by truncation, and the vegetative growth of the plant is inhibited by topping, so as to promote the formation of multiple lateral branches and give birth to flower buds.
