How to choose the right soil for planting succulent plants?

Most succulent plants grow in tropical desert areas, where the soil is poor (mostly gravel and coarse sand) with only a small amount of soil and organic matter, which is highly permeable, so we should try our best to use plants close to their original ecology when planting. Now let's introduce the plant materials that can be seen in the market:

1. Lanshi

Blue stone, also known as light stone, phytolith, pumice, is a kind of plant material with porous structure, certain water storage capacity and excellent air permeability.

2. Vermiculite

Vermiculite is made from mica processed at high temperature with good air permeability and asepsis, but it is easy to pulverize and the air permeability is very poor after pulverization. It is recommended to use it temporarily when sowing, but it is best to plant it.

3. Perlite

Perlite is also man-made, breathable and sterile; it is also easy to pulverize and floats unpleasantly when watered.

4. Coconut bran

Coconut bran is made from the brown shell of coconut, which has good air permeability and slight acidity, which is good for the areas with alkaline water quality in the north. But get rid of the fine powder when growing succulent plants.

5. Grass carbon soil

Grass carbon soil is made of organic matter accumulation, decay and carbonation, good air permeability, neutral, and a certain amount of nutrients is a good plant material. But get rid of the fine powder when growing succulent plants.

6. Peat soil

Peat soil is further carbonized by grass carbon soil, good air permeability, neutral, no nutrients is a good plant material. But get rid of the fine powder when growing succulent plants.

7. Red jade soil

Red jade soil is a kind of plant material formed by volcanic ash accumulation, with porous structure and excellent air permeability. Contains a certain amount of phosphorus and potassium fertilizer.

8. Wood carbon

Wood charcoal is fired from trees, with porous structure, no nutrients, has a strong bacteriostatic and adsorption of harmful substances.

9. Carbon shell

Carbon shell is the shell of rice which is carbonized at high temperature. it contains certain phosphorus and potassium fertilizer, good air permeability, strong bacteriostasis and adsorption of harmful substances. But it's also easy to pulverize.

10. Sand

There are many kinds of sand. What we are talking about here are weathered sand on the mountain and large gravel sand (with a particle size above 1MM). These sands have good air permeability, and some contain quartz, iron, magnesium and other trace elements that are beneficial to the absorption of plants.

The plant materials mentioned above should be matched when they are used, and the fine particles under 1MM should be removed, and those of the same size should be prepared at the ratio of inorganic matter to organic matter at 7:3. In this way, we can get as close as possible to the physiological needs of plants. There are also some plants can also be used, such as honeycomb coal ash, fairy soil, all kinds of herbivore ring fertilizer, everyone can use.
