The Latest Edition of Winter Care and Management Methods for Bougainvillea

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 southern and northern 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.

1. 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 of bougainvillea contains “mei”, it is not as cold-tolerant as China's plum blossom. On the contrary, it 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.

2. Winter Care and Management Methods for Bougainvillea

1. Watering

Because this plant is relatively afraid of cold and can tolerate a minimum temperature of only 8 degrees, in order to help this plant smoothly pass through the cold winter, it cannot be watered too much. In winter, it is generally placed in a warmer place for cultivation. If the normal amount of watering 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, in winter it is best to choose dormancy to help it smoothly pass through the winter. If fertilizer is applied at this time, it will promote its growth, thereby reducing its ability to resist cold, so in winter, all fertilizer application should be stopped.

3. Daily Management

In most parts 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 enclosed environments, during periods of strong sunlight in winter, the bougainvillea should be ventilated. 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. Timing for Moving In and Out in 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 degrees Celsius, 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 should be moved into a warm area. Different moving-in times also mean different moving-out times. In southern regions, 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. However, 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 at the end of April or the beginning of May.

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