1、 Can I use sand

You can root with sand. Due to the good permeability of sand, it is beneficial to the growth of orchid roots. If the temperature and humidity of the maintenance environment are appropriate, cultivating orchids with sand as the substrate can promote the growth of new buds and roots, and improve the rooting speed and survival rate of plants. In addition, the growth characteristics of orchids are promoting roots by wetting and buds by drying. This characteristic corresponds to the poor water retention performance of river sand, so it also promotes the rapid rooting and germination of orchids

In addition, cultivating orchids with sand can avoid the occurrence of rot or death of plant roots due to too much water in the basin and ponding in the basin. Because the sand has good permeability and poor water retention performance, it is conducive to the loss of water, which can effectively prevent the death of plants due to excessive watering. Therefore, in the root promoting and bud promoting stage, novice orchid culture can use pure river sand as the substrate of orchid culture

2、 How to judge

Observe the glossiness of plant leaves. If the leaves of the plant are shiny and grow vigorously without discoloration, it indicates that the root of the orchid grows normally you can also observe the growth of new buds. If the old seedlings grow normally and do not change color, the new buds can develop normally, grow faster and grow significantly, it indicates that the orchid is growing roots
