Why do bougainvillea flowers always fall off?

1. Improper fertilization

Many people apply fertilizers blindly because flowers need nutrients to bloom. This will not only fail to make the flowers bloom more vigorously, but will also cause the buds to fall off, causing the entire plant to wilt and the leaves to turn yellow. Another problem is that the fertilizer was chosen incorrectly. Too much nitrogen fertilizer was applied, causing the plants to grow too tall, and no appropriate phosphorus fertilizer was applied. During the flowering period, appropriate addition of phosphorus fertilizer can prolong its flowering period.

2. Improper watering

Watering too much before or during flowering will cause the flowers to fall off. The normal opening of flowers is around October-November. Starting from August-September when differentiation begins, it is necessary to properly control the application of water and reduce watering.

3. Lack of light

It likes sunlight. If there is a lack of sunlight during the flowering period and the light requirements are not met, the flower buds cannot differentiate and the buds will fall off. Appropriate sunlight can be provided during the flowering period to promote energy accumulation.
