1、 Soil quality requirements

1. Good drainage: its roots are fleshy roots, which are not resistant to water logging, so the soil for breeding it must have the characteristics of good drainage effect. Such soil is not prone to ponding, which can avoid its root rot

2. Nutrient sufficiency: it consumes a lot of nutrients during growth and flowering, so the soil for cultivating it also needs to have the characteristics of nutrient sufficiency

3. Acid soil: it is an acid soil plant, and the soil for breeding it is preferably acid soil. If you don't know how to distinguish the acidity and alkalinity of soil, you can use pH test paper. If the measured index is less than 7, it indicates that it is acidic soil

2、 Soil mixing method

1. Soil preparation based on soft plant material: the selected materials are rotten leaf soil, granular wood, pastoral soil, etc. The soil prepared with these materials has the characteristics of hard and breathable. It will agglomerate when it is held by hand, but it will scatter when it is loosened. The soil cultured plants prepared in this way can promote rooting

2. Soil preparation based on hard plant material: the selected materials are weathered rock particles, small stones, pine bark and humus soil. After mixing the above materials, screen out three specifications of soil with a screen. The large plant material is used at the bottom of the basin to facilitate drainage. The medium plant material is laid in the middle and the small plant material is laid on the top. Raising it with such soil will make it grow stronger and stronger
