Reasons Why Bougainvillea Doesn't Bloom
Today's experience sharing: Introduction to the Bougainvillea Clinic, reasons why bougainvillea doesn't bloom, let's take a look with the editor!
Some flower friends' bougainvillea doesn't bloom or blooms very sparingly, urgently needing to understand the reasons why bougainvillea doesn't bloom. Simply put, the lack of blooming in bougainvillea is mostly due to insufficient light, improper pruning leading to dense foliage, and poor soil with insufficient fertilizer. Therefore, to ensure丰满 blooming in bougainvillea, it is necessary to investigate these three aspects.
1) Light issue: This is relatively easy to investigate. Bougainvillea is a positive plant, requiring ample light during its growth period. The stronger the sunlight, the more and brighter the flowers. Conversely, if it grows in a dark environment for a long time, it will not bloom.
2) Fertilizer issue: Potted flowers all face the issue of fertilizer, especially woody flowering plants, which have a higher demand for nutrients. Depending on the size of the pot, generally once a month, during the peak growing period of bougainvillea, apply liquid fertilizer every half month, and more in higher ambient temperatures. Applying more phosphorus and potassium fertilizers is beneficial for flower bud differentiation and ensures robust flower buds.
3) Watering issue: There is a saying: "Frequent watering doesn't make flowers bloom, less watering keeps flowers continuous." Controlling water can greatly affect the flower bud differentiation of bougainvillea depending on the amount of water. Generally, water control should start about 50 days before blooming, which means if you want bougainvillea to bloom on "October First," you should start water control on August 10th. If it rains, it should be moved into a greenhouse or covered with a rainproof film to prevent the potting soil from getting wet. The water control period is about 10 days, at which point the bougainvillea's current year's branches' skin will look slightly wrinkled. After that, resume normal watering and management, and the bougainvillea will shed old leaves and sprout new ones.
4) Pruning issue: Some flower friends are reluctant to prune, leading to the dispersion of nutrients and difficulty in forming flower buds. In the spring, when bougainvillea has flower buds, some weak and diseased branches can be cut, and flower stalks should also be pruned after flowering.
The above sharing of the specific introduction to the reasons why bougainvillea doesn't bloom, hoping to bring some floral knowledge to flower enthusiasts.
