Bougainvillea only grows leaves and does not bloom? If you do not do these 3 things well, no wonder there are no flowers in summer

Recently, the backend has received many messages from flower lovers asking: the bougainvillea they grow only grows leaves and does not bloom? Why? In fact, bougainvillea not blooming in summer is closely related to care. Below, Shitou will introduce them to you one by one

First, bougainvillea is a woody vine flower and is very common in the south. The flowering time of bougainvillea is generally from November to June of the following year, and the flowering form is leaf flowers. Bougainvillea likes a growing environment with sufficient light, warmth, and humidity, and is not cold-tolerant, not drought-tolerant, and tolerant of pruning. In the process of caring for bougainvillea, if it only grows leaves and does not bloom, it is actually still because the care details are not done properly. Below, Shitou will analyze them one by one:

Insufficient light:

Bougainvillea likes sunlight very much. In the south, it is often grown in the ground, while in the north it is mostly grown in pots. Light directly affects the development of flower buds. Especially for bougainvillea that has always been kept indoors, due to lack of light, the flower buds do not develop well in spring, which directly leads to sparse flowering or even no flowering in summer. Therefore, in spring, bougainvillea must be guaranteed at least 6 hours of full sun every day.

2. Improper pruning:

Pruning of bougainvillea is generally done before and after the flowering period each year. With this pruning every year, do a heavy pruning once every five years. The pruning time before the flowering period each year is after the Chinese New Year, and it cannot be too late. If it is too late, the already developed flower buds will be cut off. The main purpose of pruning is to cut off weak branches, leggy branches, and dense branches, reduce unnecessary nutrient consumption, and give the whole plant ventilation and increase light.

Pruning after the flowering period each year is mainly to shape the plant and cut off spent flowers.

3. Improper fertilization:

Bougainvillea likes fertile soil. Fertilization is mainly done before and after the flowering period each year, and fertilization before the flowering period must be paid special attention to. Because flower buds are very sensitive to nitrogen fertilizer, after the flower buds have formed, applying nitrogen fertilizer will directly burn the flower buds to death, and finally the phenomenon of no flowering in summer will appear. Therefore, the principle of fertilization before the flowering period: do not apply nitrogen fertilizer or compound fertilizer, apply diluted phosphorus and potassium fertilizer to help the development of flower buds. Potassium dihydrogen phosphate is recommended.

Fertilization after the flowering period is mainly to supplement nutrients for the plant, and applying compound fertilizer is most suitable.

Generally, when bougainvillea does not bloom, it is mainly due to these three reasons.
