1. It is better to provide it with a better quality water for irrigation. The best choice is the rainwater, river water or well water in nature. However, if you use the tap water from your home, you need to put it aside for more than a day for irrigation

2. When maintaining orchids, do not use the original plastic pot for planting, because the plastic pot not only has poor air permeability, but also contains some toxic substances, so it needs to be replaced in time. You can choose clay pots with good air permeability, porcelain pots, purple sand pots and so on

3. Although orchid likes water very much, the water in its basin should not be too much. Always keep the humidity in its basin at about 50% to 70%. If the rotten roots are caused by heavy water, the soil should be replaced in time and replanted with new soil

4. Maintain its growth temperature at about 20 degrees and grow in a place with plenty of light

5. If the root rot is caused by the disease, take it out of the flowerpot in time, trim the diseased root system, put disinfectant on it, blow dry it in a cool and dry place, and then plant it in a new soil
