How to raise bougainvillea leaves in winter?

It's already beginning of winter, and it's almost the light snow solar term. This is Jinzhou, Shijiazhuang, Hebei where Sister Rong is located. After yesterday's rain, today's temperature is 2 ~ 8℃. Under such circumstances, Sister Rong has moved my flowers and plants indoors for maintenance, and the bougainvillea in Sister Rong's house has fallen leaves. What if the bougainvillea leaves become bare? We can find out the causes of bougainvillea leaves falling through the following aspects, and then solve the problem with the right medicine:

The temperature is too low, which leads to the defoliation of bougainvillea which likes warm environment. The optimum temperature for the growth period is 15 ~ 30℃. It can grow normally when the temperature is high in summer, and it is easy to shed leaves when the temperature is low in winter. If bougainvillea leaves have fallen because of the low temperature, we can do this.

Now bougainvillea leaves have a certain relationship with temperature, so bougainvillea can be moved indoors for maintenance. In the case of indoor heating, bougainvillea bougainvillea can grow leaves again at a temperature not lower than 15℃ and then bloom.

If you are a flower friend without heating in the south, you can put the defoliated bougainvillea in an environment above 10℃, put it in plenty of sunshine during the day, and put a plastic bag on the bougainvillea at night to let the defoliated bougainvillea grow leaves again.

Bougainvillea likes warm sunshine, and the sunshine in winter belongs to warm sunshine, so bougainvillea is very suitable for keeping in sunny places. In a cool environment, bougainvillea leaves are not easy to grow, because everything grows by the sun, except the strong sunshine in summer.

Water bougainvillea appropriately, and change the number of bougainvillea that likes warm and humid environment with the change of temperature. When watering bougainvillea, the principle of "dry thoroughly and water thoroughly" should be adopted. The so-called dryness does not mean that all the bougainvillea in the basin are dried completely, which will lead to the root system of bougainvillea dying of water shortage. The so-called dryness means that the surface of the basin soil looks dry and needs us to water it.

In a room with indoor heating in winter, watering bougainvillea can be done in the morning or at noon, not at night, which can prevent bougainvillea from absorbing water because of the low temperature at night. Besides, in a heated indoor environment, the air will be relatively dry. In this case, we should also properly spray water on bougainvillea.

When we water indoors without heating in winter, we need to avoid watering in the morning or at night, but water in the warm noon. Watered bougainvillea will absorb a lot of water in a warm afternoon, and it will not cause frostbite of bougainvillea when the temperature is low at night. In addition, when watering bougainvillea, the temperature of the water used should be consistent with the indoor temperature, so as to prevent the root system of bougainvillea from breathing with water with too low temperature.

Through such watering, bougainvillea will grow new leaves after defoliation, and bougainvillea will bloom in a warm room.

In a warm room, phosphorus and potassium fertilizer can be applied to bougainvillea, which can promote flowering. In a room with heating, we can also grow leaves in bougainvillea, and then apply some nitrogen fertilizer to promote the growth of bougainvillea. After bougainvillea blooms, we can also apply phosphorus and potassium fertilizer to bougainvillea, or spray potassium dihydrogen phosphate water-soluble fertilizer to let bougainvillea bloom beautiful flowers during the Spring Festival.

For bougainvillea without indoor heating, if the leaves can grow, let bougainvillea continue to grow, but don't apply fertilizer to prevent bougainvillea from being fattened due to low temperature.

Conclusion bougainvillea leaves due to cold in winter. We can keep bougainvillea in the warm sunshine indoors and water and fertilize reasonably according to the indoor temperature. If the indoor temperature is low, after the leaves of bougainvillea fall off, the bougainvillea can be watered at high temperature at noon in an environment above 5℃ with sufficient sunshine, which can also make bougainvillea overwinter smoothly. So we can better raise bougainvillea in winter according to our own specific conditions.
