How to deal with sunflowers in winter

1. Keep warm in time

The temperature in winter is very low, which is not conducive to the growth of sunflowers and may also cause frostbite on their roots. So move it to a warm place indoors and keep the temperature above 6℃. Generally speaking, if it is raised in the southern region, it should be placed indoors after the Descent of Frost and taken out until the Qingming Festival of the following year.

2. Reduce watering

Sunflowers themselves do not require much water, and even less water is needed during the low temperature dormancy period. Watering is usually done on sunny days. Sufficient sunlight can allow some water to evaporate and will not cause the soil in the pot to be too moist. Do not water it on cloudy days, otherwise it will be detrimental to its growth.

3. Proper pruning

Because sunflowers are not resistant to low temperatures, their leaves and stems are easily frostbitten. To reduce the possibility of it freezing, some of the leaf stems need to be cut off. The pruning should be large and don't worry about its growth. It will grow back in the spring of the following year.

4. Fertilization is strictly prohibited

Many plants cannot be fertilized in winter, and sunflowers are no exception. Although it likes fertilizer very much, it is dormant in winter and basically does not absorb nutrients. The accumulation of fertilizer will cause damage to the roots when they develop in the spring of the following year.
