How to Cultivate Bougainvillea to Bloom More
Do you know these? Details about how to cultivate bougainvillea to make it bloom more and the green plant flower cultivation methods and techniques for bougainvillea, are as follows:
Bougainvillea, also known as paper flower and cardinal flower, is a shrub native to tropical regions. It grows rapidly from April to July and blooms from October to the following June. The key to cultivating bougainvillea lies in providing suitable environmental conditions such as light, soil, and water, as well as good management practices such as fertilizing, pruning, and repotting. Here is a detailed introduction.
I. Suitable Cultivation Environment
1. Light Requirements
Bougainvillea loves light, with 8 to 12 hours of sunlight being ideal. It requires ample light to bloom normally, and insufficient sunlight can cause leaf drop. However, it needs to be shaded during the high-temperature noon of summer.
2. Soil Selection
Bougainvillea does not have special requirements for the soil, as it is tolerant to poor soil, alkalinity, and drought. Any soil can be used to cultivate bougainvillea, but for better growth, it is best to use loose, well-draining acidic soil. For potted plants, a mixture of decomposed leaf soil and garden soil can be used, with a small amount of coarse sand added.
3. Temperature Requirements
Bougainvillea is sensitive to severe cold, with the optimal growth temperature being 15°C. It grows fastest at temperatures between 15°C and 30°C, and the winter temperature should be above 3°C. The blooming period requires temperatures above 15°C. In areas where the winter temperature is above 3°C in the south, it can be cultivated outdoors. In the north, it needs to be kept warm indoors during winter.
4. Water Requirements
Water the bougainvillea when the soil is dry, and 30 to 35 days before the blooming period, water should be restricted. Each watering should be done when the leaves start to wilt, which can promote the formation of flower buds. Normal watering can resume after the buds appear.
II. Cultivation Management
1. Fertilization
Regular and moderate fertilization is needed during the growing season and blooming period. In the growing season, apply cake fertilizer water every 7 to 10 days, and after the flowers fade, apply nitrogen fertilizer every 7 days, especially in summer, apply fertilizer every 15 to 20 days, and apply a solution of potassium dihydrogen phosphate as a foliar fertilizer every 15 days. Top-dressing in summer can promote the growth of flowering branches.
2. Pruning
Regular pruning is required. Bougainvillea is tolerant to pruning, and its branches and leaves can grow densely. To make it bloom more and have a beautiful shape, it is necessary to regularly remove withered and yellow leaves and weak branches. Pruning can be done 1 to 3 times during the growing season to reduce the density of branches and leaves, prevent diseases and pests, control plant height and shape, and promote the growth of lateral branches and flower buds. After the flowers fade, the spent flowers should be pruned promptly.
3. Disease and Pest Control
Common diseases and pests of bougainvillea include dieback disease, leaf beetles, and aphids. Diseases caused by pathogenic bacteria can be controlled with agents such as thiophanate-methyl.
4. Repotting and Soil Replacement
Bougainvillea is usually cultivated outdoors. Long-term watering and rain can cause soil compaction, so it is necessary to loosen the soil frequently. As bougainvillea blooms heavily, the soil nutrients can easily become deficient, and the root system grows quickly, requiring more space. Regular repotting is necessary, and it can be done once a year.
