1、 Soil requirements

1. Ventilation: the first requirement for the cultured Rosa roxburghii is ventilation, which can ensure the respiration of the root, so as not to make the soil too hard and sticky, which is easy to cause obstacles to the growth of Rosa roxburghii and affect the subsequent growth. Therefore, the best choice is sandy soil, which can meet this demand

2. Fertility: nutrients are essential for growth. If you want to grow well, you must ensure sufficient nutrition to provide nutrient support for Rosa roxburghii. Before preparing soil, the supplement of base fertilizer is very important

3. Drainage: it is also necessary to ensure the drainage effect. If you accidentally water too much, it can be discharged in time and will not accumulate in the flowerpot and affect the root, so you need to add a little large particles to the soil

2、 Soil mixing method

Soil quality requirements are very important. The effect of selecting semi Sandy and semi fertile soil is good. The soil can be prepared with rotten leaf soil, sandy soil, garden soil and vermiculite. The proportion can be adjusted according to the actual situation. In order to ensure good nutritional effect, a small amount of fertilizer should be mixed without too much. It can be used as enough base fertilizer. It should be noted that in order to ensure a good soil environment, the flowerpot can be changed once every 1-2 years to ensure sufficient nutrient support
