1、 Increase illumination

The metabolism of green plants is inseparable from sunlight, especially in spring. Whether the amount of sunlight is sufficient directly affects the growth of plants, and silver queen is no exception. When the silver queen is given light in spring, the light time cannot be less than five hours. If the sun is too strong, shade work needs to be done

2、 Control temperature

It is sensitive to temperature. If the growth environment temperature does not conform to its growth habits, it will directly affect the development of plants. If the temperature is lower than five degrees, the plants will be easily frostbitten. Therefore, we should start to prevent cold at about ten degrees. The temperature suitable for its growth is about 18 degrees. The temperature difference in early spring is relatively large. It is best not to maintain in the open field. The survival rate of open field maintenance in early spring is not high

3、 Increase watering

Silver queen likes humidity, but the root system is not resistant to waterlogging. Therefore, the amount of watering should be controlled when increasing the number of watering times. The amount of watering is generally based on the standard that the soil is completely wet and there is no ponding in the soil. The temperature in early spring is relatively low, and the temperature of the pouring water is best similar to the growth environment temperature. If the root of the plant is found to be rotten by blisters, it is necessary to pull out the plant, repair the rotten place, dry it and replant it
