1、 Poor water quality

Reason: the smooth sailing of water culture has requirements for water quality. If the water is not changed for a long time, the water quality will become turbid and unclean. Smooth sailing. Growing in such water quality for a long time may lead to root rot

Treatment method: pay attention to changing water regularly during maintenance, and keep the water quality clean. If rotten roots are found, take the plants out of the container, cut off the rotten roots and put them in carbendazim solution for sterilization. Clean the container, replace it with new water quality, and then replant it

2、 Root hypoxia

Cause: if the water level is relatively high, the roots will be soaked in water, resulting in hypoxia and rotten roots

Treatment method: the amount of water added should be moderate, and the water level should not be too high. After rotten roots, in addition to cutting off the rotten roots, it is also necessary to pour out a little water from the container to expose part of the roots so that the roots can be exposed to air

3、 Low temperature

Reason: plain sailing can't stand the cold climate. If the temperature is relatively low, there will be problems in the growth, which will also lead to rotten roots

Treatment method: if the surrounding temperature is relatively low, it is necessary to move the plant indoors and keep the temperature above 10 degrees, which can prevent the problem of rotten roots. After rotten roots appear, the rotten part is cut off and placed in a warm environment
