1、 Timely insulation

The temperature in winter is very low, which is unfavorable to the growth of sunflower and frostbite its roots. So move it to a warm place indoors and keep the temperature above 6 ℃. Generally, if you breed in the south, you have to put it indoors after frost, and wait until the next Qingming Festival to take it out

2、 Reduce watering

Sunflower itself has little demand for water, and it needs less water during low-temperature dormancy. Watering is mostly carried out in sunny days. Sufficient light can volatilize some water and will not cause the basin soil to be too wet. You can't water on cloudy days, otherwise it's bad for its growth

3、 Proper pruning

Because sunflower is not resistant to low temperature, its leaves and stems are easy to be frostbitten. In order to reduce the possibility of freezing, some leaves and stems need to be cut off. The pruning range should be large. Don't worry about its growth. It will continue to grow back after the beginning of spring the next year

4、 Fertilization is strictly prohibited

Many plants cannot be fertilized in winter, and sunflower is no exception. Although it likes fertilizer very much, it is in dormancy in winter and can hardly absorb nutrients. The accumulation of fertilizer will cause damage to the root when it develops in the spring next year
