1. To make orchids take root quickly, you can plant them with fresh sawdust. Using fresh sawdust to cultivate orchids can keep moisture, ventilate, ventilate and drain quickly, which is beneficial to the development of orchid roots. Because sawdust is loose, has large gaps and strong water retention, it can provide a good rooting environment for orchids. It should be noted that the use time of miscellaneous wood bran should not be too long, and orchids should be replaced immediately after taking root. 2. adjust the pH value. Orchids take root quickly. By adjusting the pH value of soil, suitable acidic substrate can be given to promote rooting. Specific operation: water can be diluted with salicylic acid solution, or aspirin powder dissolved in alcohol can be diluted with a lot of water, and then the orchids can be watered slowly. 3. Fertilization promotes rootless orchids. They can't absorb nutrients and water through roots, but only use leaves and stems to protect stems from pests and diseases. It is also necessary to spray fertilizer on the leaves to promote the growth of orchids and make them grow new roots quickly. Orchids are fertilizer-loving plants, and base fertilizer should be applied when planting, and liquid fertilizer and foliar fertilizer should be added during the growing period. 4. The environment of temperature control and pruning orchid growth requires neither cold nor hot. Therefore, in order for orchids to take root quickly, it is necessary to give them a suitable temperature, keep warm when it is cold, and cool down when it is hot; In addition, orchids should be pruned properly in the rooting process to remove diseased and dead leaves and reduce nutrient loss.

Rooting of hydroponic orchids

First, treat the roots of orchids. Soak the roots in clear water for two days to see if the roots are broken. If it is, it won't work. If the root system is healthy and complete, then hydroponics can be carried out. In the process of cultivation, put it in a place with light. Sufficient light can promote the full development of its root system, make its leaves grow thicker and fuller, and there will be no phenomenon of excessive growth. If the mouth of the container is large, the root can be fixed and fixed with pebbles, which looks particularly primitive. With gravity, the roots can grow stronger and stronger, so as not to drift askew.
