Can orchids be grown on weathered rocks?

Orchids can be grown on weathered rocks because they contain some silica and other trace elements. Generally, these elements can make the roots grow better after being absorbed by orchids. However, if too much is used, there will be a lack of nutrients. Therefore, it is necessary to control the amount and replenish nutrients in time.

Advantages and Disadvantages of Weathered Stone Orchids

Advantages: The texture of weathered stone is relatively soft, and it is generally in the form of particles, so it has good air permeability and drainage when used, and will not cause root suffocation, and it has the advantage of preventing water accumulation.

Disadvantages: If the amount of weathered stone used is not controlled, it will lead to a lack of nutrients in the soil. The relatively single nutrition will affect the growth of orchids, and the growth will be uneven.

How to grow orchids from weathered rocks

1. Particle processing: Weathered stone needs to be dispersed into particles of different sizes when used. Do not use weathered stone that is too large. You can disinfect it before use.

2. Soil preparation: When using weathered stone, it needs to be matched with other materials. Generally, you can choose to use it with leaf mold, pond mud and expanded clay, so that the soil will be richer in nutrients.
