The reason why the latest hydrangea does not blossom only with long leaves

Hydrangea gets its name because the flower is shaped like hydrangea, and it is favored by people because of its beautiful shape and rich colors, but some friends find that their hydrangeas have long leaves but do not blossom in the process of breeding. what is the reason for this? Come and have a look with the editor.

1. Improper pruning

The flowering period of hydrangea is generally from April to June. The new seedlings generally do not blossom in that year and will not blossom until the next year. Basically, hydrangea flowers generally bloom on the old branches. However, if the old branches are not pruned in time, it will affect the flowering of the following year, but we should also be careful not to prune all the old branches, otherwise it will be extremely difficult to blossom the next year. Attention should also be paid to pruning after hydrangea flowering. 3-4 bud points are retained on each branch, and the rest are all cut off. The best time is generally from August to September, otherwise it will affect the flowering of the following year.

2. The reason of illumination

Hydrangea flowers and plants with short sunshine during flower bud differentiation, if the light is too long during flower bud differentiation, it will affect flower bud differentiation, which will lead to little flowering. However, lack of light will also lead to non-flowering, hydrangea shade-resistant, but long-term exposure to sunlight will not grow badly, it will affect photosynthesis, resulting in less possibility of flowering. Therefore, it is necessary to give it sufficient light when breeding, so that it can produce more beautiful flowers.

3. The reason of fertilizer and water

Plant flowering is inseparable from fertilizer and water, especially in spring, it is necessary to water him with phosphorus and potassium fertilizer in advance to promote flower bud differentiation, so as to make it blossom. However, it should be noted that before flowering, nitrogen fertilizer should not be applied too much, otherwise it will affect flowering, improper watering is also one of the reasons why hydrangea does not bloom. If there is too much watering in the watering process, it will lead to basin soil drying, can not absorb effective water, do not blossom, too much watering will cause stagnant water, resulting in pot soil root rot, will not blossom. Watering and fertilization of hydrangea in breeding should be decided according to plant growth and season.

4. Temperature reason

In general, the most suitable temperature of hydrangea is 18-25 degrees. If it is in high temperature in summer, it will grow and not blossom, but when the winter temperature is too low, it will lead to plant freezing injury, unable to differentiate flower buds, and will not blossom. Once the temperature exceeds 30 degrees in summer maintenance, shading treatment and spraying water fog are needed to reduce the temperature and temperature in time. In winter, it is recommended to keep the temperature above 10 in the greenhouse.

The above is the introduction of the reason why hydrangea only grows leaves but does not blossom. I hope it can help you. If you want to know more about it, please follow us.
