1. Select appropriate soil

Hemp leaf Spiraea prefers fertile land, so when planting, we should choose the soil with loose soil and good water permeability. In this way, its roots can be better protected and meet the needs of nutrition. In addition, it is also necessary to find those with particularly large soil viscosity, and then add some fine sand or small stones to adjust the soil better. Don't choose the soil that is especially sticky and condensed by wet soil. It's bad for the root, so it won't be easy to survive. Sandy soil is the best

2. Suitable light and temperature

Spiraea hemp has high requirements for sunshine. It should ensure sufficient sunshine and good ventilation. Generally, it grows and develops best under the condition of about 25 ° temperature. Although it can be exposed to the ground for winter, if the temperature is lower than minus 25 °, freezing injury will occur, which may also lead to death. Therefore, it is necessary to control the temperature to meet its needs for temperature

3. Proper watering and fertilization

Before planting, we must ensure that there is sufficient base fertilizer and sufficient water. Generally, it is best to use rotten manure. When it is about to bloom, it should be applied with phosphorus and potassium fertilizer for 2 to 3 times. When the autumn is approaching, it is best to carry out a wintering fertilizer with rotten and hot manure. In winter, we should stop fertilization and reduce the amount of watering

4. Perform proper shaping and trimming

When it grows to a certain extent, it is necessary to prune Spiraea. The best season is spring. Its dead branches should be cut off before budding in early spring, and some too dense branches, sick weak branches and aging branches should be cut off to keep it beautiful. In this way, it can flourish and grow vigorously, which brings a sense of beauty to the whole courtyard
