1. Increase the temperature: For indoor maintenance in winter, ensure that the temperature is above 7 and below 10 . Cut off the water supply and wait for the temperature to rise before watering.
2. Less watering: When the temperature is lower than 15 , control the water, wait for the pot soil to dry completely, and slip less water along the edge of the pot. When the temperature is higher than 15 , weigh the weight of the pot soil with your hand, and feel that it is obviously lighter to water thoroughly.
3. More light: Bougainvillea spectabilis itself likes light, and the light in winter is warm and soft, so it should be sunned more. Adequate light can also improve the local maintenance temperature, so that Bougainvillea spectabilis can accumulate nutrients and survive the winter safely.
4. No fertilization: If the temperature is lower than 15 , no fertilization will be applied, otherwise the plant will be in a dormant state, and it is easy to cause fertilizer injury after fertilization. If the temperature is higher than 15 for indoor heating in winter, thin fertilizer can be applied frequently, and the concentration is lighter and safer.
In winter, when the temperature is low, the domestic Bougainvillea must not be heavily pruned. After heavy pruning, the leaves of the Bougainvillea will become fewer, which will affect the photosynthesis of the plant. The organic matter transported to the root system will also be reduced. If the root system cannot absorb nutrients, the seedlings will be stiff and will not grow or die.So winter Bougainvillea, do not re-cut, if the winter Bougainvillea is still flowering, such as plant flower failure, the residual flowers and flowers under 1-2 pairs of leaves light cut on the line.
