This article summary: This article introduces the relevant experience of how to cultivate Bougainvillea to make it bloom more and the tips for making Bougainvillea bloom frequently. Let's follow the editor to see the specific content!
Bougainvillea has a relatively long blooming period, from November to the next June, and it blooms all year round in warm regions. In South and Southwest China, it is mostly planted in the ground, while in the Yangtze River Valley and the northern regions, it is planted in pots. Bougainvillea is an important ornamental tree that produces beautiful and unique bright red flowers. Bougainvillea comes in various colors such as bright red, orange yellow, purple red, and milky white, making it highly ornamental. The flowers of Bougainvillea are bright and have a long blooming period, making them very popular among people. Many flower enthusiasts encounter a problem when cultivating Bougainvillea: the flowers become smaller and smaller as they bloom. How can Bougainvillea be made to bloom more vigorously?
To make Bougainvillea bloom more vigorously, it is necessary to meet the conditions required for the growth and development of Bougainvillea. First, understand the habits of Bougainvillea, then care for Bougainvillea according to its habits. As long as the conditions required for the growth and development of Bougainvillea are met, it will grow more vigorously and bloom more.
Bougainvillea is native to Brazil in South America and prefers a warm and humid climate. It is not cold-resistant and can only be planted in pots in the Yangtze River Valley and northern regions, with wintering in greenhouses. It is best to place it in a sunny window sill indoors at 18-20°C during winter. Low temperatures in winter can cause leaf drop, with the optimal growth temperature being 20-30°C. Bougainvillea is drought-tolerant, pruning-tolerant, has a strong growth habit, likes water but dislikes waterlogging in the soil. Bougainvillea enjoys sunlight, and insufficient light can affect blooming. It requires plenty of sunlight and often does not bloom or blooms very little in shaded areas. Bougainvillea is not picky about soil, but grows best in sandy loam. Therefore, to cultivate Bougainvillea well and produce many bright flowers, it is necessary to meet the requirements of Bougainvillea's growth conditions.
1. Change the potting soil every year: After a period of time, the soil in the pot becomes increasingly compacted, and the original nutrients in the soil have been largely depleted, causing the flowers to become smaller and fewer. To avoid affecting the growth and development of the plant, it is necessary to change the pot and soil every year, replacing the small pot with a larger one and the old, nutrient-depleted soil with fresh, nutrient-rich soil. The purpose of repotting is to create a good potting environment for continuous growth, which helps maintain the soil's aeration, drainage, water retention, and nutrient retention functions, meeting the nutrient needs of Bougainvillea's growth and blooming.
2. Pruning: Bougainvillea tolerates pruning. Pruning and shaping can adjust the growth of Bougainvillea, control the plant shape, and promote the sprouting of new branches and blooming. Without pruning, Bougainvillea blooms few flowers, only at the top of the new shoots. Pruning can promote more vigorous blooming, with potted Bougainvillea usually pruned into a dome shape, and heavily pruned for small leaves and flowers, removing dense, inner, and vigorous branches to promote the differentiation of new flower buds.
3. Strengthen water and fertilizer management: Bougainvillea requires a large amount of water, especially in summer, and insufficient water supply can cause leaf drop. It is necessary to water in the morning and evening. In spring and autumn, water after the soil is completely dry in the afternoon. In winter, when the plant is in a dormant state, water should be controlled, and watering after flowering can be reduced. Soil that is too wet can cause leaf drop and root rot. During the growing season, apply nitrogen fertilizer once a week, and add 2-3 times of phosphorus fertilizer during the flowering period. Fertilize according to the plant's needs, applying thin layers of fertilizer frequently. If the branches and leaves are small and show signs of nitrogen deficiency, apply nitrogen fertilizer. If the branches are soft and weak, and the flowers droop, showing signs of phosphorus and potassium deficiency, apply phosphorus and potassium fertilizers.
4. Keep the potting soil loose: If chemical fertilizers are used for a long time, the potting soil can become compacted, leading to insufficient water and fertilizer supply and resulting in small leaves and flowers. Therefore, organic fertilizers should be used primarily, and the soil should be loosened regularly with decomposed cake fertilizer and washing rice water.
5. Light management: If the pot of Bougainvillea is placed in a shady and humid place, it can cause insufficient light, resulting in thin branches, yellow leaves, small flowers, and few blooms. Therefore, move the pot to a sunny place for maintenance and avoid placing it in a place without sunlight for an extended period. Insufficient light can lead to thin plants, small flowers, and increased susceptibility to disease. It is not suitable to care for Bougainvillea in a place with insufficient sunlight.
The above is a specific introduction to how to cultivate Bougainvillea to make it bloom more and the tips for making Bougainvillea bloom frequently. It is hoped to bring some plant knowledge to green enthusiasts.
