Bougainvillea can bloom all year round, but it is difficult to do it in family culture. Generally, it only blooms once a year. The higher latitude, the earlier flowering time.
In places such as Guangdong and Hainan where the climate is suitable, its flowering period is relatively long, from December to February of the next year, while in the relatively cold north, such as Beijing, its flowering period is relatively short, generally around October.
It is necessary to provide enough sunlight every day to plant the bougainvillea, and keep the illumination time between 8-10 hours. Plant in the north, pay attention to water control in summer, and ensure indoor temperature in winter, not lower than 8 ℃, and ensure 8 hours of sunshine. In addition, pay attention to the application of P and K fertilizer and pruning of flower branches.
