Can orchids grow roots in sand? How to judge whether they are growing roots

1. Can sand be used?

You can use sand to root. Because sand has good permeability, it is beneficial to the growth of orchid roots. If the temperature and humidity of the maintenance environment are suitable, using sand as a substrate to grow orchids can promote the growth of new buds and new roots, and increase the rooting speed and survival rate of the plants. Another growth characteristic of orchids is that moisture promotes rooting, while dryness promotes budding. This characteristic corresponds exactly to the poor water retention capacity of river sand, so it also promotes the rapid rooting and germination of orchids.

In addition, using sand to grow orchids can avoid the situation where water accumulates in the pot due to inadequate control of the amount of watering, which can cause the roots of the plant to rot or die. Because sand has good permeability and poor water retention, it is conducive to water loss and can effectively prevent the death of plants due to excessive watering. Therefore, for novices who are growing orchids, during the root and bud promotion period, they can use pure river sand planting material as the substrate for growing orchids.

2. How to judge

Observe the glossiness of the plant's leaves. If the leaves of the plant are glossy and shiny and growing vigorously without any discoloration, it means that the roots of the orchid are growing normally. You can also observe the growth of new shoots. If the old seedlings grow normally and do not change color, the new buds can develop normally, and the growth rate is fast and obvious, it means that the orchid is growing roots.
