Yushu can tolerate the lowest temperature of about 5 .If the temperature is lower, it may suffer from frostbite and various growth problems.If the temperature is very low, it may freeze to death directly.To be on the safe side, when the temperature drops to 7-10 degrees Celsius, it needs to be moved indoors to a warm place.This will keep it from freezing.
1. Increase sunlight: It prefers sunlight.In winter, the light intensity is very low, so we should try to keep it in a good light place.This will enable it to synthesize more nutrients, so that it can survive the winter more safely.
2. Reduce watering: In winter, when the temperature is very low, it grows very slowly.At this time, water should be controlled for it.You can't water it until the soil has dried out.Otherwise, its root system may rot because of water in the soil.If the soil has not been dry, you can also stop watering and use the way of spraying water to replenish it.
3. Stop fertilizing: Because it grows slowly in winter, it does not need to absorb a lot of nutrients from the soil.So it is not recommended to fertilize it at this time.Let it absorb the original nutrients from the soil, and it can meet its needs.If fertilizer is applied, the fertilizer that can not be absorbed in time may remain in the flower soil, causing damage to its root system, leading to root burning.When the temperature rises to more than 15 C in the spring of next year, it can be fertilized.
