Bougainvillea can bloom in winter. Its flowering period is from September to May of the next year, which will include winter months. However, not every region can bloom in winter. It is also related to temperature. In the south of China, the temperature is relatively high in winter, so the probability of flowering is higher in winter. On the contrary, in the cold north, the probability of flowering in winter will be smaller
1. Temperature: it must be kept above 15 degrees, so it has a great chance of flowering. If the temperature is too low, it can't bloom. So it's better to move it indoors in winter, so that it has a great chance to bloom.
2. Light: This is another important factor besides temperature. Be sure to put it where the light is good, so that it will bloom
3. Fertilizer: it can be used moderately, but not too much in winter. Species mainly choose phosphorus and potassium fertilizer, which can promote flowering.
4. Ventilation: proper ventilation. The wind should not be too strong, and it should not be directed at it.
5. Watering: water moderately to provide water for flowering. But it itself is afraid of waterlogging, so the quantity must be well controlled.
