You can use sand to grow roots. Because of the good permeability of sand, 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 cultivate orchids can promote the growth of new shoots and new roots, and increase the rooting speed and survival rate of the plants. Growing orchids in sand can avoid problems caused by watering. Because sand has good permeability but poor water retention performance, it is conducive to water loss and can effectively prevent plant death due to excessive watering.

1. Can sand be used?

Sand can be used to grow roots. Because of 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, using sand as a substrate to cultivate orchids can promote the growth of new shoots and new roots, and increase the rooting speed and survival rate of the plants. There are also the growth characteristics of orchids, which are that moisture promotes roots and dryness promotes buds. This characteristic corresponds to the poor water retention of river sand, so it also promotes the rapid rooting and germination of orchids.

In addition, using sand to cultivate orchids can avoid excessive watering. If the amount is not properly controlled, there will be too much water in the pot, and water will accumulate in the pot, causing the roots of the plants to rot or die. Because sand has good permeability but poor water retention performance, it is conducive to water loss and can effectively prevent plant death due to excessive watering. Therefore, novices who are growing orchids can use pure river sand planting material as the substrate for growing orchids during the root-promoting and bud-promoting stage.

2. How to judge

Observation The glossiness of plant leaves. If the leaves of the plant are shiny and vigorous, and there is no 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, and the new shoots can develop normally and grow quickly and clearly, it means that the orchid is growing roots.
