Why do bougainvillea flowers fade in color?
Some flower enthusiasts ask: Why do the bougainvillea flowers I grow become lighter in color? They are not as vibrant as when I first bought them?
In fact, the situation where bougainvillea flowers fade in color is common among many flower enthusiasts, and the reasons usually include the following two.
1. Lack of sunlight
Bougainvillea loves sunlight very much. If there is not enough sunlight, the bougainvillea is prone to excessive growth, reduced flowering, or even no flowering at all. This is known to many bougainvillea growers, so they always maintain good sunlight during cultivation.
But when bougainvillea starts to bloom, many enthusiasts move it indoors for display, which can lead to insufficient sunlight. Then they notice that the color of the bougainvillea flowers gradually fades, and it is also very easy to drop flowers and buds. This is caused by a severe lack of sunlight.
Therefore, during the flowering period, try not to change the sunlight and avoid moving it around, as this can easily lead to flower drop. Too much change in sunlight can also cause the color of bougainvillea flowers to fade. If it is autumn or winter and it is quite cold outside, moving the bougainvillea indoors for insulation and placing it on a south-facing balcony to receive sunlight is necessary; otherwise, faded flowers and dropped flowers are inevitable.
2. Lack of fertilizer
In addition to the impact of sunlight, the influence of fertilization on the color of bougainvillea flowers is also significant. Bougainvillea has a large quantity and a long blooming period, requiring a high amount of phosphorus and potassium fertilizers. If bougainvillea is not fertilized for a long time, even if it blooms, the color of the flowers will be lighter and not as vibrant.
How to make bougainvillea flowers colorful
If you want bougainvillea flowers to be colorful and not fade, in addition to maintaining sufficient sunlight during the growing period, it is also necessary to provide adequate sunlight during the flowering period.
At the same time, when bougainvillea forms flower buds, it should be fertilized more with phosphorus and potassium fertilizers to promote the growth of the flower buds. You can fertilize with monopotassium phosphate once every 7 days and apply bone meal organic fertilizer once a month.
Change the potting soil every spring and add enough base fertilizer to the soil to ensure that the bougainvillea has sufficient fertilizer throughout its growing period (G-Y), which helps the plant grow vigorously and bloom more.
