What is the reason for the leaves of green radish to turn black?

1. Reasons why leaves turn black

1. The light is too strong: Pothos cannot tolerate the sun, especially the strong sunlight in summer. If placed in direct sunlight, the leaves will be sunburned over time, and black spots will appear on the leaves, gradually spreading throughout the leaves.

2. Temperature unsuitability: Its growth has certain requirements on the environment and it is not resistant to high temperatures or cold. If the temperature is not controlled during high temperatures in summer or low temperatures in winter, the plants will be harmed and yellow or black leaves will easily appear.

3. Infection with pests and diseases: If the environment provided during the management period is not suitable, such as high temperature, high humidity and poor air permeability, it will be easy to be infected by pests and diseases, which will hinder the growth of the entire plant and cause various growth problems. In severe cases, the plant will die.

2. Treatment Methods

No matter what the cause of the blackening of leaves is, it must be treated as soon as possible to avoid further deterioration. If you get sunburned due to excessive sunlight, you should move to a cool place and spray water frequently to keep moisturized, so that you can slowly recover. If the temperature is not suitable, pay attention to temperature control in the later summer and winter. In summer, more ventilation is needed to cool down the house. In winter, the house should be moved indoors and the temperature should be controlled above 10 degrees. If infected with pests and diseases, the diseased leaves should be removed as soon as possible and sprayed with fungicides to sterilize and avoid infection. In addition, the maintenance environment needs to be changed in the later stage.
