When does bougainvillea bloom and why doesn't it bloom

1. Flowering time

The flowering time of Bougainvillea is affected by temperature. Due to the difference in climate between the north and the south, the flowering time is also different. It is generally from November of each year to around June of the following year. The temperature in the south is not very low in winter, so it generally blooms around November. It may bloom in spring in the north. Due to differences in variety, flowering times may vary slightly. The flowering period lasts for a long time, generally about 2 months. If the temperature and the surrounding environment are suitable, it may last about 4 months.

2. Why doesn't it bloom?

1. Lack of sunlight: Bougainvillea needs sufficient nutrient support to bloom. If it is kept in a dark place for a long time, the conditions for flowering cannot be met and it will not bloom. It needs to be given sufficient sunlight.

2. Too much watering: Watering needs to be controlled before flowering. If too much water is given, the plant will only grow but not bloom. Watering needs to be controlled before flowering.

3. Insufficient temperature: If the temperature is too low, it will also affect flowering. The temperature needs to be raised and maintained within a range suitable for flowering.

4. Lack of fertilizer: Nutrients can support flowering, especially for Bougainvillea, which has a large number of flowers and a long flowering period. If there is a lack of fertilizer, it will make it difficult to bloom. It is necessary to add phosphorus and potassium fertilizers before the flowering period.
