2. It is necessary to supplement some phosphorus and potassium fertilizers appropriately.

Bougainvillea likes loose and fertile slightly acidic soil.

4. Flowering plants should be turned over once a year before germination in early spring. When changing pots, cut off the densely aged branches with scissors.

5. During the high temperature period from July to September in summer, bougainvillea can be watered once in the morning and once in the evening.

In winter, bougainvillea is placed in front of the south window, and the illumination time should not be less than 8 hours, otherwise a large number of leaves will easily appear; The daily illumination time is controlled at about 9 hours, and the flower buds can bloom after one and a half months.

Water once a day in spring and autumn, and once in the morning and evening in summer. In winter, when the temperature is low and the plants are dormant, it is necessary to control watering and keep the basin soil moist.

Because of long-term watering, fertilization and rain erosion, basin soil is easy to harden. Therefore, it is necessary to loosen the soil regularly and remove weeds in the basin soil to facilitate the growth of bougainvillea.

Otherwise, the basin soil will harden and accumulate water, which will easily cause root rot or poor growth of bougainvillea.

In addition, bougainvillea grows faster, with developed roots and many fibrous roots, which need to be changed once a year.
