Why Is My Bougainvillea Dropping Flowers? Here's the Latest Analysis

Not long ago, Qinnong Network just covered the reasons why bougainvillea won't bloom. You finally managed to get your own bougainvillea to flower, only for the blossoms to drop off before long, which is a real letdown after all that joy. So why does bougainvillea drop its flowers? Below, Qinnong Network will explain it for everyone.

A bougainvillea growing under normal conditions actually won't drop its flowers, so don't think that just getting your bougainvillea to bloom means everything is fine. If flower drop does occur, it is one of the signs that something is wrong with your care. Let's take a closer look at what causes bougainvillea to shed its flowers!

1. External Factors

If a bougainvillea is frequently moved during its flowering period, or if people handle and play with its flowering branches, or if it is exposed to wind and rain, flower drop may result. So during the flowering period we should keep the bougainvillea in a fixed spot, one that gets plenty of sunlight while also sheltering it from wind and rain, and at the same time prevent others from casually handling the flowers.

2. Improper Watering

During the flowering period, bougainvillea should not be watered unless something unexpected happens; this can extend the flowering period, whereas watering will instead cause the flowers to drop. If during this time you notice the leaves looking wilted, you can lightly mist the leaves to increase the humidity in the air.

3. Improper Fertilizing

During the flowering period you can appropriately apply some phosphorus fertilizer, which helps with flowering and extends the flowering period, while reducing the amount of nitrogen fertilizer applied. If you fertilize the bougainvillea too much, or choose the wrong fertilizer, it will cause root burn, and the whole plant will wilt, with yellowing leaves and flower drop.

4. Insufficient Light

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

The above is an introduction to some of what Qinnong Network has to share about bougainvillea flower drop, and we hope it can be of some help to everyone. In fact, bougainvillea is a plant with fairly 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 will be just around the corner.
