1、 Increase nutrients

If it is a new plant, it needs to be mixed with base fertilizer in the soil before planting to meet the nutrient needs of subsequent growth. If it is an old plant, you need to use thin fertilizer once a month, or you can use slow release fertilizer, which can be buried in the soil

2、 Increase watering

It is not a wet plant and has strong drought resistance. Therefore, when watering, we must control the amount and watering times. After thawing in early spring, it needs to use thawing water once, and the water should completely pour the soil through. After the thawing water is poured, there is no need to water for the time being. After the climate is stable in spring, it can be watered once or twice a half month

3、 Trim properly

The purpose of spring pruning is to improve the ornamental quality and concentrate nutrients. When pruning, first remove the unhealthy and damaged branches, and finally set it on the basis of pruning to make it look more ornamental

4、 Pest protection

It is relatively cold resistant, and the plants with good cold resistance have strong resistance to pests, but in the process of maintenance, protective measures still need to be taken to avoid plant frostbite. If you are unfortunately infected with a pest, you need to spray it with a professional agent. If there are pests in the soil, the plants need to be pulled out and replanted into the new soil, and the old soil can be discarded after disinfection
