1. Adjust the room temperatureReason: The indoor temperature for growing green radish is too low, so its leaves will easily rot, wilt and turn yellow, and even turn black over time. Remedy: The temperature of the breeding environment should be adjusted in time, and the lowest temperature should be around 10℃. If the room temperature is too low, the plants will easily be frozen. Especially in northern regions, appropriate measures to keep out the cold are needed. 2. Control wateringReason: Don't water it too much, because it is very afraid of water accumulation. If you give it too much water during maintenance, the root rot will cause the yellow leaves to droop. Over time, the leaves will droop and turn black. Remedy: The amount of watering should be greatly reduced. If there is excess water in the potting soil, it should be drained out as soon as possible, and ventilation should be increased. The amount of watering in the later stage should also be controlled well, and water accumulation should be avoided. 3. Increase light exposureReason: The plant grows in a dark place for a long time. At first, the leaves will turn yellow, become soft and droop. If the maintenance position is not changed in time, its leaves will turn black. Remedy: It should be moved to a location with sunlight as soon as possible. It should not be kept in the dark for a long time. It is best to move it to a location with light so that the plant can receive scattered light. It should not be directly exposed to direct sunlight. |
