What to do when the color of Bougainvillea fades?
Bougainvillea is loved by gardening enthusiasts for its hardiness, abundant flowering, and long blooming period. Autumn is the peak blooming season for Bougainvillea, but some gardening enthusiasts are puzzled because the two pots of Bougainvillea they bought, which are supposed to be red and orange varieties, are now blooming all white. What's going on?
Reasons for the fading and whitening of Bougainvillea flowers
The color of Bougainvillea flowers is not fixed and can change easily due to environmental factors, similar to roses. This is exactly the charm of Bougainvillea. The factors affecting the color of Bougainvillea flowers can be summarized into the following four points.
1. Light
Bougainvillea is a sun-loving plant and loves light. If the location where Bougainvillea is grown does not have enough light, it will not only lead to the plant's branches growing too long and only producing leaves with few flowers, but also cause the flower color to be significantly lighter. Varieties that are originally red are prone to producing pink flowers.
Even if the Bougainvillea is already blooming, if it is moved indoors without sufficient sunlight, the flower color will gradually become dull and it is prone to dropping flowers and buds.
Therefore, whether it is in the growing period or the blooming period, it is necessary to maintain sufficient light.
2. Fertilization and Watering

In addition to light affecting the color of Bougainvillea flowers, fertilization and watering also affect the color of the flowers. If the phosphorus and potassium fertilizers are insufficient for Bougainvillea, the blooming flowers will become dull and lackluster.
About half a month before Bougainvillea enters the bud stage, phosphorus and potassium fertilizers can start to be supplemented. These fertilizers can promote the differentiation of flower buds in Bougainvillea, increase the number of flower buds, and make the flower color more vibrant.
3. Small temperature difference in indoor cultivation
Light and fertilization are the most basic conditions. If these conditions are met, Bougainvillea can bloom normally. However, if there is still a phenomenon of faded and pale flowers, the effect of temperature difference should be considered.
Many gardening enthusiasts grow Bougainvillea indoors, where the temperature difference is very small. However, many Bougainvillea varieties need to be in an environment with a significant day-night temperature difference to have more vibrant colors, such as green cherry and Zhangzhou red cherry.
