Bougainvillea Winter Care Management Methods and Precautions

The scientific name of bougainvillea is Bougainvillea glabra, and it also has other aliases such as paper flower and purple bougainvillea. It originated in Brazil, and in China it is mainly distributed in southern regions such as Fujian, Guangdong, Hainan, Guangxi and Yunnan. It is suitable for planting in courtyards, parks and other locations. Bougainvillea has particularly strong adaptability and can be cultivated in both northern and southern China, but because bougainvillea is not cold-tolerant, it requires special care in winter. Below, Qinnong Network introduces the methods for winter care of bougainvillea.

I. Growth habits of bougainvillea

Bougainvillea originated in Brazil, and its growing environment is mainly tropical climate, so bougainvillea likes sufficient light and a warm environment. Although the name bougainvillea contains "mei", it is not as cold-tolerant as China's plum blossom. On the contrary, this is a plant that is not very cold-tolerant, and when the temperature drops to a certain level in winter, it will enter a dormant state.

II. Bougainvillea winter care management methods

1. Watering

Because this plant is relatively afraid of cold and can tolerate a minimum temperature of only 8 degrees, watering cannot be excessive in order to help this plant successfully get through the cold winter. In winter, it is generally placed in a warmer place for cultivation. If the normal watering amount is maintained as usual at this time, then this plant will grow luxuriantly because of the higher temperature and relatively suitable moisture. Under such circumstances, its own cold resistance will decline further, which is very bad for its growth. Finally, it is worth noting that if watering is really needed, it is best to water with warm water.

2. Fertilizing

Because this plant has particularly weak cold resistance, it is best to choose dormancy in winter to help it successfully get through the winter. If fertilizer is applied at this time, it will promote its growth and thereby reduce its ability to resist cold, so in winter, applying any fertilizer to it should be stopped.

3. Daily management

In most areas of China, when cultivating bougainvillea in winter, it needs to be moved indoors. If there is no heating indoors and the temperature is relatively low, it is best to move the bougainvillea into a greenhouse for cultivation. Because both indoors and greenhouses can be called closed environments, bougainvillea should be ventilated during periods of strong sunlight in winter. Bougainvillea in a dormant state in winter is more suitable for its growth, so if the temperature is relatively high, appropriate cooling treatment can also be carried out.

4. Time for moving into and out of warm areas

Because the climate difference between northern and southern China is relatively large, when cultivating bougainvillea in China, the care methods in the north and south are also different, such as the time for moving it into a greenhouse or indoors. In southern China, when the winter temperature is lower than 8°C, usually at the end of November or the beginning of December, the potted bougainvillea should be moved indoors or into a greenhouse, while winter in northern China comes early, and usually by mid-November the bougainvillea must be moved into a warm area. Different moving-in times mean different moving-out times as well. In southern China, the temperature begins to warm up around March, and the potted plant can be moved out of the warm area according to specific weather conditions, while winter in the north lasts a long time. If it is also moved out of the warm area in March, it is very easy to cause the bougainvillea to suffer frostbite. Once the bougainvillea is frozen, it cannot normally produce flowers during the flowering period. The suitable time for moving it out of the warm area in the north is late April or early May.

The above is the introduction from Qinnong Network about winter care methods for bougainvillea. Bougainvillea is very beautiful during its flowering period and is a very attractive ornamental plant. Its flowers can be used as medicine, but the stems and leaves are toxic, and accidental ingestion may cause diarrhea, so attention should be paid during cultivation!
