What causes bougainvillea to drop its flowers?

Not long ago, Qinnong Network introduced the reasons why bougainvillea does not bloom. After finally getting your own bougainvillea to bloom, the flowers drop before long, which is quite a letdown. So why does bougainvillea drop its flowers? Below, Qinnong Network will explain.

Bougainvillea growing under normal conditions actually does not drop its flowers, so do not think that everything is fine once you have gotten your bougainvillea to bloom. If flower drop occurs, it is also one of the signs that something is wrong with your care. Let us take a specific look at what causes bougainvillea to drop its flowers!

I. External factors

If the bougainvillea is frequently moved during its flowering period or its flowering branches are handled and played with, or if it is exposed to wind and rain, flower drop may occur. Therefore, during the flowering period we should keep the bougainvillea fixed in one position, with both ample sunlight and shelter from wind and rain, while also preventing others from casually playing with the flowers.

II. Improper watering

During the flowering period of bougainvillea, if nothing unexpected happens, do not water it; this can extend the flowering period. Watering instead causes the flowers to drop. If during this period the leaves are found to be wilting, you can appropriately mist the leaves to increase the humidity in the air.

III. Improper fertilizing

During the flowering period, you can appropriately apply some phosphorus fertilizer, which helps flowering and extends the flowering period, and reduce the amount of nitrogen fertilizer applied. If the bougainvillea is over-fertilized or the wrong fertilizer is chosen, it will cause root burn in the bougainvillea, and the whole plant will wilt, the leaves will turn yellow, and the flowers will drop.

IV. Insufficient light

Bougainvillea is a plant that relatively likes light, especially during the flowering period. In particular, the flowering period of bougainvillea is mainly in winter and spring, when the light is not strong, so the bougainvillea can enjoy all-day light, which helps it grow lush branches and leaves and produce clusters of flowers. If during the flowering period the light does not meet the requirements, the bougainvillea's growth will become abnormal and cause flower drop.

The above is an introduction from Qinnong Network about bougainvillea dropping its flowers, and we hope it can be of some help to everyone. In fact, bougainvillea is a plant with relatively strong adaptability and can be grown in both the north and south of our country, so as long as we meet the requirements of daily care, blooming is just around the corner.
