1. Water quality problem: If the water is not changed for a long time during the water culture period, the water quality will become worse, and there will be pollutants in it, which will hinder the growth for a long time, and the oxygen contained in it will also become less, and the plant will rot its roots due to lack of oxygen.We should pay attention to changing water in time so that the water quality can grow normally.
2. Excessive fertilization: Fertilizer should be put into the water-raised chlorophytum regularly to ensure adequate nutrients.But if the fertilizer is excessive, it will burn the roots, which will lead to root rot.Later fertilization should be less rather than more, each time put a few grains of urea fertilizer on the line, it can meet its demand for nutrients.
3. The temperature is too low: the temperature is required to be high in water culture, and it is best to maintain the temperature between 15 and 25 degrees at ordinary times.Cold tolerance is very poor, if the temperature is less than 12 degrees, it will grow slowly, less than 5 degrees will be frostbite, slowly the root system will rot, to control the temperature, winter is best above 12 degrees.
When rotten roots are found, they should be removed as soon as possible, and the rotten parts should be cut off.After pruning, disinfection treatment is needed, if there is no disinfectant, the wound should be dried in the shade before it can be potted, so that it can grow normally in the later period.If not handled in time, it will be infected and root rot will be more serious.In addition, containers should be disinfected to avoid bacterial infection.
