An Introduction to the Characteristics of Zimu Stone and Its Uses in Horticultural Planting

Zimu stone is a common natural stone material, named for the way small stones often accompany a large stone, resembling a mother carrying her child. It is hard in texture with distinct granules, and it is used both in horticultural planting and in the field of ornamental stones, especially being fairly common in the cultivation of orchids, succulents and other plants with high requirements for air permeability.

As a planting auxiliary material, the greatest advantage of Zimu stone is its good air permeability and drainage. There are gaps between the granules, allowing the roots to breathe freely, and after watering, excess water can also drain away quickly, reducing the risk of root rot. At the same time, it has stable properties, is not prone to pulverizing or compacting, is clean and odorless, and after washing can also be reused.

In practical use, Zimu stone is often mixed with substrates such as bark, peanut shells and humus soil to grow orchids, bonsai and succulent plants. It can also be spread alone on the surface of the pot to press down the soil and retain moisture, or placed at the bottom of the pot to enhance drainage. Before use, it is recommended to sift out the dust, then soak and rinse it with clean water, and pot it after drying, which is more reliable.

When purchasing, those with uniform granule size, natural color and little powder are preferable. It should be noted that among the general public there are also ornamental stones with peculiar shapes, in which a mother stone embraces a child stone, that are called Zimu stone. Such stones are mainly used for display and handling, and are of different uses from the granular stone material used in horticultural planting, so they can be distinguished according to actual needs when buying.
