Management of summer cherry blossoms
1. Grass mulching has high temperature in summer, evaporates quickly, and the amount of water is more than that in other seasons, but it is still necessary to adhere to the principle of "no dry, no watering". Cherry blossoms are shallow root plants, and the roots are close to the surface of the soil and are easy to dry. Straw can be used to cover the roots of the trees, which can not only maintain moisture and resist drought, but also prevent the capillary roots of cherry trees from being exposed, and greatly reduce the evaporation of soil water. 2. Dry entanglement and drought prevention can be wrapped with straw within 2 to 3 years after planting to prevent the trunk from drying. Because the cherry blossom bark is thin, wrapping the bark can prevent it.
