1、 Illumination

1. The plant receives too much sunlight for too long, which will affect the production of chlorophyll in the plant, so the leaves will become thin and red

2. Usually you can put the plant in the shade to recover, and the plant can recover in about a month

2、 Temperature

1. If the temperature of the breeding environment is too low or the environmental temperature difference is too large, it will lead to the stagnation of plant growth and the phenomenon of red leaves

2. At this time, you need to put the plants in a higher and constant temperature environment, and wait a few weeks for the plants to return to normal

3、 Growth and development

If the environment in which the plant is located, whether temperature or surrounding humidity, is suitable for its growth, and the plant has not been damaged by insects, the plant may be due to normal growth and development, resulting in the metabolism of red leaves. It usually gets better after a while

4、 Moisture

1. If the plant is seriously short of water, the leaves of the plant may turn red

2. At this time, we should supplement water to the plant in time and loosen the soil properly
