Can sunflowers survive the winter? How long can sunflowers live?

1. Can it survive the winter?

Sunflowers have poor cold resistance and the temperature is low in winter. If the temperature is not controlled, it will be frozen to death if left outdoors and will not survive the winter. But if you move it indoors in time, provide it with a warm environment, and pay attention to maintenance methods, it can survive safely and will not freeze to death.

2. Methods of wintering

Move it indoors after the temperature drops. The indoor temperature should be maintained between 15 and 20 degrees, and the minimum should be above 10 degrees to ensure that it will not get frostbite. At this time, the growth is slow, the water requirement is small, and the water evaporates slowly, so you should reduce the amount of watering and do not water casually unless the soil is dry. The soil will be better suited for wintering if it is kept dry. In addition, pay attention to getting more sun exposure. It is light-loving and the light in winter is very mild. It can be placed in direct sunlight all day long. It can accumulate nutrients with sufficient light, so that it will bloom as scheduled in the spring of next year.

3. How long can you live?

There are many varieties of sun plants, and common varieties are usually annual plants, which means they can live for one year. After the flowers fade in winter, the plant stops growing and slowly dies. However, some species are perennial and can live for three or four years. In addition, how long they can live also depends on the environment provided under normal circumstances, especially the low temperatures in winter. The temperature must be controlled well to ensure safe wintering, so that they can live longer.
