1、 Sufficient light

The growth and flowering of Rieger Begonia is inseparable from sufficient light. The sunlight in winter is relatively mild and not particularly strong, so it can increase the lighting time and even realize all day sunshine. Through the irradiation of light, it can not only synthesize nutrients to promote growth, but also improve the temperature of the plant itself

2、 Raise temperature

The most suitable temperature for the growth of Rieger Begonia is about 18-22 ℃, which is far from the temperature in winter. Therefore, warm keeping measures should be taken to improve the temperature in the growth environment. In winter, it's best to move indoors for overwintering. The minimum temperature should not be lower than 5 ℃, and it's best to keep it above 10 ℃

3、 Controlled watering

Winter growth is very slow, so watering needs to be controlled, not a lot of watering. You can judge whether to water according to the situation of basin soil. Wait until the soil is dry before watering. The amount of watering should not be too much. If the soil is too wet, bacteria will breed

4、 Suspend fertilization

Before winter, secondary organic fertilizer can be applied to the plant, which can provide nutrients, enhance the disease resistance of the plant and improve the resistance. Fertilization can be suspended in winter. If the indoor temperature is appropriate, an appropriate amount of fertilizer can also be applied

5、 Precautions

Although the Rieger Begonia should be moved indoors in winter, it cannot be placed in front of the heating equipment. The window should be opened properly at noon for ventilation
