1、 Soil material

1. Feilong's soil preparation requires ventilation and drainage. Coarse sand can be used to make the whole soil breathable and have good permeability. Coal ash can also be used, which is also good for enhancing air permeability. In addition to these two, volcanic stone, vermiculite and perlite can also be used to promote ventilation and drainage

2. It also has certain nutrition. It can add plant ash, which is rich in phosphorus and potassium, which can provide the growth needs of flying dragons and inhibit the breeding of bacteria. You can also add bone meal or charcoal to it, which can provide certain nutrition for the plant

2、 Soil mixing method

The soil preparation scheme is relatively flexible. Garden soil or peat soil can be used as the main soil. These two kinds of soil can be divided into two parts respectively, and then three parts of coarse sand and one part of charcoal are added. You can also use peat soil and red jade soil as the main soil, and then add coarse sand and volcanic stone. The effect is also good. In addition to these two soil preparation methods, the above materials can also be mixed and mixed evenly, which can be used as cultivation soil
