What kind of stone is vermiculite for growing flowers? Is vermiculite suitable for leaf cuttings?

People who know how to grow flowers know that you can’t plant flowers with just clay alone. It’s better to mix it with sand, humus, vermiculite and other media to increase the water permeability and air permeability of the soil. Vermiculite is a very common type of stone, so what kind of stone is it?

What kind of stone is vermiculite for growing flowers?

Vermiculite is a pure natural ore, non-toxic and pollution-free. It is a relatively rare ore and belongs to silicate minerals. The structure of this mineral is monoclinic crystal, and it looks very similar to mica.

Vermiculite plays a great role in adjusting the nutrition of the soil. After being heated at high temperature, vermiculite will expand. As long as there is high humidity, it will continue to expand and peel off layer by layer. What peels off is a layer of very thin fragments until a piece of ore is peeled off. This is the finished product that people use.

Vermiculite itself only contains some mineral elements, and does not contain nitrogen, phosphorus and potassium elements, so it is only suitable for seed seedlings and cuttings seedlings, and can improve the viscosity of clay soil. It is not recommended to use a large amount of it during the growth period of general crops.

Is vermiculite suitable for leaf cuttings?

Vermiculite can maintain the humidity of the planting environment, make seeds germinate better and promote rooting. When sowing by leaf cuttings, you can mix in appropriate amounts of vermiculite, which has strong water retention and air permeability.

Vermiculite is a water-rich substance rich in minerals. It has a good adsorption effect on water and can retain fertilizers appropriately, which is helpful for improving soil. Moreover, it is very loose and breathable, and is used to promote the slow release of nutrients and promote the growth of plant roots. It has a good effect and is also a granular soil used to improve soil.

Vermiculite soil has many specifications. Fine vermiculite is generally used for leaf cuttings and sowing. Coarse vermiculite can be used with soil. It is best to use vermiculite leaf cuttings with peat, because vermiculite absorbs water very well and easily accumulates water. Piece with peat and other particles to ensure faster drainage. Otherwise, it is easy to die in summer.

Where does vermiculite come from?

When this mineral is heated at high temperatures, it will expand under the action of high temperatures. As long as there is high humidity, it will continue to expand and peel off layer by layer. What peels off is a layer of very thin fragments until a piece of ore is peeled off. This is the finished product that people use.

When this ore is baked at high temperature, its volume can quickly expand to six to twenty times, and its specific gravity after expansion is sixty to one hundred and eighty kilograms per cubic meter.

When it is baked at high temperature, it is like a piece of very dry sticky mud. After repeated exposure to rain and sun, it will eventually be weathered into a pile of very small particles. It is the same principle. When this ore is heated at high temperature and peels off layer by layer, it will expand continuously. The movement of expansion and peeling is very similar to the movement of leeches. So people call this stone "vermiculite".
