1、 Reasons for rotten roots

1. Water quality problem: if the water is not changed for a long time during water culture, the water quality becomes worse, there are pollutants in it, which will hinder the growth for a long time, and the oxygen contained in it will become less, and the plant will rot its roots due to lack of oxygen. We should pay attention to changing the water in time to ensure that the water quality is clean and can grow normally

2. Excessive fertilization: the hydroponic Chlorophytum should put fertilizer into it regularly to ensure sufficient nutrients. But if there is too much fertilizer, it will burn the roots, resulting in root rot. In the later stage of fertilization, it is better to put a few grains of urea fertilizer each time, which can meet its demand for nutrients

3. The temperature is too low: the requirement for temperature is high during water culture. It is best to maintain it between 15 ℃ and 25 ℃. The cold resistance is extremely poor. If the temperature is lower than 12 degrees, it will grow slowly. If it is lower than 5 degrees, it will be frostbitten, and the root system will rot slowly. It is necessary to control the temperature. It is best to be above 12 degrees in winter

2、 Treatment of rotten roots

If rotten roots are found, take them out as soon as possible and cut off the rotten parts. Disinfect after pruning. If there is no disinfectant, put it in a cool place to dry the wound before putting it into the basin, so that it can grow normally in the later stage. If the treatment is not timely, it will be infected and the root rot will be more serious. In addition, disinfect the container to avoid bacterial infection
