The winter in the north is relatively cold, usually the temperature will be lower than zero degree, and the bougainvillea may be easily frostbitten under the environment of lower than 5 degree, resulting in failure to bloom, so the north is not suitable for planting and maintenance. But if we can do a good job in keeping warm, making it safe for winter, planting can also grow well.
If you want it to survive the winter safely in the way of planting in the north, you should pay attention to the methods. In winter, the branches can be pruned properly to save nutrient consumption. It is also necessary to apply fertilizer and spray water appropriately, so as to warm the roots and prevent frostbite. After fertilizing and spraying water, cover its branches with straw felt to prevent the cold wind from blowing to the plant and causing freezing damage. In this way, the winter can be spent.
When planting in the north, we should pay attention to choose the place with sufficient light. It must not be planted in the dark. The lack of light will hinder the differentiation of its branches and buds, which is not good for winter. In addition, we should also pay attention to water control in winter, basically do not need to water, otherwise the soil is easy to freeze, resulting in root injury.
