Cultivation methods and matters needing attention of bougainvillea;

First, the cultivation method of bougainvillea: 1, temperature bougainvillea is not cold-resistant, and likes to grow in a warm environment. If the weather is cold, it is easy to cause leaves to fall off. Therefore, bougainvillea usually grows in warm southern areas and is difficult to cultivate in cold northern areas. The environmental temperature suitable for bougainvillea growth should not be lower than 10 degrees Celsius, and it will cause death if it is lower than 3 degrees Celsius. Therefore, when cultivating bougainvillea, we should pay attention to adjusting the cultivation methods according to the temperature change.

2, moisturizing bougainvillea is afraid of drowning, too much water will cause the phenomenon of boring roots. Therefore, when watering bougainvillea, we should take no watering as the principle, and water it thoroughly as soon as it is watered. The watering amount of bougainvillea should be controlled at seedling stage, and it should be properly watered at flowering stage on the basis of the original watering principle to ensure sufficient water in the basin soil.

3. The soil bougainvillea likes acid and is suitable for planting in slightly acidic soil. I am afraid of stagnant water and waterlogging, so the soil I choose to plant should have good drainage and permeability, so that the roots of bougainvillea can breathe. In addition, the soil should have a certain fertility to ensure that bougainvillea has enough nutrients to grow and develop during seedling development.

4, fertilization bougainvillea likes fertilizer, and it needs to be fertilized in time to supplement nutrients for the plant during the growth period. Except for no fertilization at flowering stage, fertilization is applied every five days in other growth periods, mainly with decomposed organic fertilizer. Entering hibernation in winter can reduce the number of fertilization or not.

2. Note: 1. If bougainvillea is reared indoors, if it grows some sprawling branches, it should be pruned in time, otherwise it will not only affect the flowering, but also affect the plant type in the later stage, and it will grow in disorder.

2. When bougainvillea wants to grow more flowers, it is also necessary to pinch the tops in time, especially bougainvillea in the prosperous period. Generally, when its branches grow to about 20~30 cm, it will pinch off the tender branches at the top, which will promote the growth of more branches, form more bracts and bloom more flowers in the future.

3. The growth of bougainvillea must meet the light conditions, otherwise it will affect its normal flowering period and flowering quality. It is best to plant bougainvillea in spring, because the soil is loose and fertile and the temperature is stable, which is beneficial to the normal growth of bougainvillea.
