1. Specific requirements

Looseness and good ventilation: these two aspects are similar. If they meet the requirements, the respiration of the plant will not be greatly hindered and can promote its rapid growth

More humus: in terms of nutrition. With more nutrition, it can be adequately supplied to grow and then bloom. Moreover, this is not the only benefit. On the other hand, it can also improve the structure of soil and make it more water and fertilizer conservation

Partial acidity: in terms of pH, we should choose acidic soil. If the selected soil is alkaline, the leaves of the plant will turn yellow and may even die. However, it does not need to be too acidic. It can be slightly acidic with a pH value of 5.5 to 6.5

2. What kind of soil

Generally speaking, rotten leaf soil is better. First of all, it is a typical acidic soil. In addition, it can basically meet the above requirements. Among all the saprophytic soils, pine leaf humus is the most effective. We can dig it from under the pine trees in the forest, or we can use it in the courtyard where there are many pine and cypress trees. Of course, more than one can be used. There are many other available soils, such as nutrient soil and pond mud in flower shops

3. Precautions

① We should avoid those soils that are particularly sticky, such as red soil. This kind of soil is not suitable for plant growth

② In order to ensure the subsequent nutrition supply, an appropriate amount of base fertilizer can be added to the soil

③ If the water permeability is not very good, some cinder can be added
