When Does Bougainvillea Bloom? A Detailed Guide to Its Flowering Period

1. When It Blooms

Its flowers stay in full bloom for a relatively long time, and both the flowers and leaves are attractive, so many people like it very much. Its flowering period can last as long as four months, and with good care it can bloom all year round, but because improper home care methods are common, it cannot bloom for that long.

In many cases, it can bloom several times a year, but the exact duration is affected by temperature; if the weather is very hot, the period is relatively short. It generally blooms between April and November, and some varieties differ in timing. In addition, flowers grown in greenhouses bloom at different times from wild ones.

2. How to Judge the Flowering Period

According to the experience of flower growers, as long as the temperature does not fall below 10 degrees and it is given sufficient fertilizer and water, it has the potential to bloom. Judging when it will bloom depends on the temperature of the growing location. In Guangdong, for example, it can bloom from December to January, and may even bloom in February. In Guilin, Guangxi, it can only bloom from October to November; the temperature there is relatively suitable, not cold, with a daily average temperature of 12 degrees, so its flowering period is also relatively long. If it is in Beijing, it generally blooms in October, adding festive cheer during National Day.

Overall, the higher the latitude, the earlier it blooms, but this is not absolute. We can control its flowering time by adjusting the temperature. If we want it to bloom earlier, we let the temperature be slightly higher; if we want it to bloom later, we let the temperature be slightly lower. If controlled well enough, it can even be made to bloom until New Year's Day.

Generally, we can have it bloom from October to November, which is more helpful for it to overwinter safely.
