1. Requirements for soil

(1) The soil should be loose. Such soil is convenient for plants to breathe, which is conducive to growth. Moreover, loose soil is not easy to agglomerate, and the frequency of soil change does not need to be too high

(2) The soil should contain as much nutrients as possible. Only in this way can the plants grow vigorously and do not need too much fertilizer

(3) The drainage of the soil is better because the plants are afraid of waterlogging. The air permeability is also good, which is conducive to the development of roots

(4) According to the characteristics of the plant itself, the soil must be acidic, and the pH value is preferably between 6.5 and 6.8, which is slightly acidic

2. Specific preparation method

There are many specific methods. Here are only a few, and their effects are good on the whole

(1) It is prepared by mixing peat soil with coarse sand. The main components of peat soil are all kinds of grass, leaves and roots, which have more nutrition. Adding coarse sand will improve air permeability and drainage. Therefore, generally speaking, this method basically meets the requirements

(2) If there is no peat soil, rotten leaf soil can also be used. Some coarse sand can also be added. If you feel inadequate nutrition, you can also add some organic fertilizer, bone meal and so on

(3) You can also use mountain mud, vegetable garden soil and humus to mix them in equal quantities. Then add some coarse sand and some bone meal. You can also add plant ash to adjust the pH. This method is more troublesome and has the best effect
