There are many peat sellers in the flower market. This kind of soil is rich in nutrients, and the soil gap is also very large, so its air permeability is very good. With this kind of soil, the soil is not easy to harden.
This kind of soil mostly exists under the trees in the forest. After the leaves are eroded by the rain, they will become rotten leaf soil after natural fermentation. The air permeability and drainage effect of saprophytic soil are also very good, and it also has great fertility. However, there will be a large number of bacteria and eggs in it. It must be disinfected before it can be used to grow flowers.
It is similar to the production principle of saprophytic soil, and it is also formed by fermentation for a long time. Its water holding capacity is not very good, but the air permeability is also very good, not only that, it has a good insect repellent effect.
If you want to increase the air permeability of cultivated soil, you can also buy some coconut bran, which is a relatively permeable and soft cultivation medium. But it can not be used alone, because there is no nutrition in it. It is better to use it with other soil
