Can orchids be grown on the gravel on the construction site?

The gravel on the construction site can be used to grow orchids, because the gravel on the construction site is granular and can increase the air permeability of the soil when used. However, this material contains more alkaline substances, so the alkaline substances must be removed before use.

The pros and cons of growing orchids on gravel on construction sites

Advantages: The gravel on the construction site is heavy in texture and has a good fixing effect. When it is spread in the flowerpot, it can also make the soil more breathable and drainable, which can promote the germination and growth of orchid roots.

Disadvantages: The gravel on the construction site contains a lot of alkaline substances. If used directly, it will affect the acid-base balance in the soil. In serious cases, the roots of the orchid will be damaged, which will affect its growth.

How to grow orchids on gravel on construction sites

1. Selection and disinfection: The gravel on the construction site needs to be soaked in water to test the alkali content before use. If there is too much alkali, it needs to be soaked and heated in high-temperature water, and then some particles of appropriate size can be selected.

2. Soil preparation: The gravel on the construction site needs to be mixed with leaf mold, pine bark and peanut shells when used. This will increase the fertility of the soil and allow the orchid to grow vigorously.
