1、 Peat soil

There are many people selling peat soil in the flower market. This kind of soil is rich in nutrition, and the gap of the soil is also large, so its air permeability is very good. The soil is not easy to harden when raising flowers with this soil

2、 Saprophytic soil

This kind of soil mostly exists under the trees in the forest. After the fallen leaves are corroded by rain, they will become rotten leaf soil after natural ripening and fermentation. Rotten leaf soil has good ventilation and drainage effect, and has great fertility. However, there will be a large number of bacteria and insect eggs in it. It must be disinfected before it can be used to raise flowers

3、 Pine needle soil

It is similar to the production principle of saprophytic leaf soil, and it is also formed after a long time of fermentation. Its water holding capacity is not very good, but its air permeability is also very good. Not only that, it also has a good insect repellent effect

4、 Coconut bran

If you want to increase the air permeability of cultivation soil, you can also buy some coconut bran, which is a relatively breathable and soft cultivation substrate. But it can't be used alone, because there is no nutrition in it. It's best to use it with other soils
