Can bougainvillea be grown outdoors?

Bougainvillea is a flower plant that blooms very frequently, and many people like to grow one in their homes. Bougainvillea can be cultivated outdoors, but whether it is suitable for outdoor cultivation depends on your geographical location and climatic conditions. Let’s talk specifically about whether Bougainvillea can be cultivated outdoors?

1. Lighting requirements

Bougainvillea likes light and needs plenty of sunlight to bloom normally. Therefore, when cultivated outdoors, it should be ensured that Bougainvillea can receive sufficient sunlight, at least 8 to 12 hours of light per day.

2. Temperature requirements

Bougainvillea is afraid of severe cold. The best growth temperature is 15℃, and it grows fastest when the temperature is between 15 and 30℃. In areas in the south where the temperature is above 3°C in winter, it can be cultivated outdoors, while in northern areas, attention should be paid to keeping warm in winter and overwintering in a warm room.

3. Northern Region

In the north, due to the low temperatures in winter, bougainvillea is not so easy to survive and can only grow and bloom in a warm environment. In the north, bougainvillea should be moved indoors in November and pruned before bringing it indoors.

4. Southern Region

Bougainvillea can be grown outdoors in the south without any problems. In the warm areas of the south, the winter temperature is above 10 degrees, so bougainvillea, whether planted in the ground or in pots, can safely overwinter outdoors.

5. Central Region

The winter in Jiangsu, Zhejiang and central China is relatively cold compared to the south, but relatively warm compared to the north. In winter, the temperature is often below 0 degrees, and the cliff-like change in temperature is especially fatal to bougainvillea. Therefore, in these areas, special attention should be paid to weather changes in winter, and bougainvillea should be moved indoors when the temperature drops below 5 degrees.

To sum up, Bougainvillea can be cultivated outdoors, but whether it is suitable for outdoor cultivation depends on the climatic conditions of your location. In warm southern regions, bougainvillea can adapt well to open-air environments; in northern and central regions, due to the low temperatures in winter, it may need to overwinter indoors.
