Why does Bougainvillea grow many leaves but not bloom (it only grows leaves and grows taller)?

First, sufficient light can promote flowering

Bougainvillea is a short-day flower plant, which means that the lighting time is best controlled within 6 to 12 hours.

If it is placed in a dimly lit location indoors, it will not be able to carry out photosynthesis, causing the reproductive organs to fail to mature, and in the end only leaves will grow but no flowers will bloom.

If it is placed in a location where it is exposed to sunlight for a long time, it will always be in a state of vegetative growth and will not be able to promote the maturation of its reproductive organs.

Therefore, it is recommended to provide 6 to 8 hours of sunlight every day during the flowering period, which can promote the plant to enter the flowering state.

Second, rich nutrition can promote flowering

Bougainvillea is relatively tolerant of poor soil environments, but it needs rich nutrients to bloom. If it has not been fertilized and maintained, the plant will not grow normally and will not be able to bloom.

If you continue to use nitrogen fertilizer for maintenance and management, the leaves will grow wildly until they are no longer able to bloom.

Therefore, it is recommended to carry out timely maintenance and management of nutritional supplements. For example, before the autumn flowering season arrives, potassium dihydrogen phosphate, which has a flowering-promoting effect, should be used for maintenance.

After diluting with clean water, repeat the process every 20 days until the number of flowers decreases or stops blooming, depending on the specific situation.

In addition, after the flowering period is over, it is recommended to use nutritious cake fertilizer for maintenance to help the plant recover.

Third, controlling watering can promote flowering

Bougainvillea is very sensitive to water and needs to be watered when the soil is dry and watered thoroughly to meet the plant's water requirements for growth.

If the plant is kept in an overly moist state for a long time, it will not only fail to bloom, but will also cause root rot.

During the flowering period, it is recommended to control water maintenance, which can have the effect of promoting flowering. For example, after seeing the leaves droop slightly, water thoroughly for maintenance management, and repeat this cycle about three times.

At this time, it is necessary to carry out light-proof maintenance and use soft light for maintenance.

Fourth, pruning branches can promote flowering

Bougainvillea has a strong ability to branch out, which means it is more resistant to pruning. If it has not been pruned and maintained, it will cause the branches and leaves to grow too long, which will over-disperse the nutrients of the plant, and finally the leaves will grow but not bloom.

Therefore, it is recommended that pruning and maintenance should be carried out when you see branches growing too long, leaves turning yellow, and flowers withering.
