1、 What is the reason for rotten roots

1. Watering too much: butterfly orchid likes a humid environment and cannot grow without water, but pay attention not to water too much, otherwise it is difficult for the plants to absorb it. Over time, it is easy to accumulate water, which will hinder the root respiration and lead to rotten roots

2. Too much fertilization: fertilize it with thin fertilizer and apply it frequently. It is best to apply it after dilution, so that the fertilizer solution can be absorbed by the plant more easily. If too much fertilizer is applied at one time or high concentration of fertilizer solution is easy to cause fertilizer damage, root burning will occur, and the root system will rot

3. Soil discomfort: it requires extremely high soil permeability and good drainage. If it is too sticky, it is difficult to breathe, and it is easy to rot after a long time

2、 How to deal with rotten roots

1. Take off the pot and prune the roots: once the root system is rotten, take off the pot as soon as possible and take the plant out of the flower pot. Also prepare tools after disinfection, cut off the rotten roots, disinfect the cut wounds, put them in a ventilated and dark place to dry the wounds, and then put them in a basin

2. Replace the soil and put it in the basin: after the plant has rotten roots, the original basin soil can no longer be used. There are bacteria in it, so all of them should be replaced. The soil should be loose, breathable and permeable. When ready, you can plant in a basin again. Pay attention to put it in a ventilated and cool place in the early stage, control light and water, and restore management after adaptation
