Reasons for Milan Leaves Turning Red1. From a physiological perspective
The redness of Milan leaves is caused by a decrease in the content of chlorophyll in the plant and an increase in the content of pigments such as carotenoids and anthocyanins. In autumn, as the temperature gradually decreases and the intensity of sunlight weakens, the plant slows down photosynthesis to adapt to environmental changes, leading to the degradation of chlorophyll and making pigments such as carotenoids and anthocyanins visible in the leaves.
2. Environmental factors
In addition to physiological factors, environmental factors also affect the redness of Milan leaves. Light, water, and soil nutrients all have an impact on the growth and development of plants. In a suitable environment, Milan leaves are more likely to turn red.
