1. Leaf spotA major reason for this phenomenon is leaf spot disease. Plants infected with this disease will grow black spots on their leaves. If you find that this is the reason, you can solve it yourself. Solution: Generally speaking, we have to clean up the diseased leaves first, because it is difficult to eliminate the black spots on it no matter how we take care of it. Then we have to ensure ventilation. Of course, this is not a way to eradicate the disease. Finally, we have to use a special agent to deal with this disease. Of course, this agent cannot be used casually. We have to dilute it so that the leaves will not be burned due to the concentration. 2. AirIf we keep it in a place where there is no wind, even the best plants will be hit hard, so this is also an obvious reason why the green radish grows black spots. Solution: Every few days we need to move it outside the room and let it bask in the sun. It is best to place it in a ventilated place at ordinary times. This is an important way to solve black spots caused by air problems. 3. LightingAlthough we cannot give it direct sunlight, it does not mean that it does not like scattered sunlight. If it is often in a dark place, it is not impossible for it to develop black spots. Solution: It is best to put it outside in the sun in the morning and evening. 4. ColdIt cannot withstand very low temperatures, and if it is frozen, black spots will easily appear. Solution: Take certain warming measures in winter to help it survive the winter safely. |
