(1) first of all, it should be loose, that is to say, air permeability. If it is not loose, the root respiration of the plant will be hindered, and then the transportation of water and nutrients will be in trouble, and the growth will become weak.
(2) Secondly, it should be fertile. Sufficient nutrition supply can ensure the vigorous growth of plants, and it will also reduce the trouble of fertilization.
(3) good water permeability. In this way, after each watering, the water can more fully penetrate into the lower part of the soil, which can not only make the plant fully absorb water, but also make the root rot.
(4) acid soil is also needed, which is determined by plant characteristics. In alkaline soil, the growth of plants is not good.
(1) the simplest way is to directly use the nutrient soil bought from the store. It is rich in nutrients, and has good air permeability and water permeability. The overall effect is good. However, some friends do not want to use this kind of soil, so if the conditions can be achieved, the soil prepared by themselves will be better.
(2) there are many ways to make it by yourself. Slightly simple method: garden soil, rotten leaf soil and coarse sand can be mixed evenly, each accounting for one third. There are also more troublesome methods: with garden soil six, stable manure two as base fertilizer, coarse sand two, peanut cake one.
No matter what kind of soil you choose, it's best to disinfect it before using it.
