1、 Soil quality requirements

1. Air permeability: it is very drought resistant, can not stand under the water wet environment, and the root is difficult to bear the ponding. Therefore, the requirements for the soil should first be air permeability, not too sticky. If it is too sticky and hardened, the whole growth will have problems and become weak. In the process of breeding, Sandy is the most suitable

2. Drainage: it also needs to be able to drain water to prevent water from accumulating in it. Once too much water is applied, it can flow out along it, reducing the possibility of rotten roots. Coarse sand can be applied to ensure this

3. Nutrition: growth is essential and needs nutrition. It can ensure the soil with nutrition, lay a good foundation for plant growth, and have sufficient nutrition. Then fertilization can reduce the frequency and maintenance management will be much easier

2、 Soil mixing method

Garden soil, rotten leaf soil and coarse sand can be fully mixed in the ratio of 1:1:2. The prepared soil is more appropriate. A little bone powder and plant ash need to be added as appropriate to ensure the nutrition of base fertilizer. Garden soil and peat soil mainly ensure nutrition, coarse sand can increase drainage and air permeability, bone meal and plant ash can provide nutrition, which is very beneficial to growth
