Usually, the time to see red leaves starts in early to mid-October, and the viewing period lasts about a month and can extend to mid-to-late November.

2. Reasons why red leaves turn red

Leaves not only have green leaves, but also anthocyanins, lutein and carotene. However, the content of the latter three is low, so most people cannot see it. After entering autumn, the temperature will slowly drop, and the chlorophyll in the leaves will be decomposed into roots and trunks. When the chlorophyll content in leaves is low, the remaining pigment content is high, so they change color. Moreover, in autumn, low temperatures will synthesize anthocyanins. When anthocyanins meet acidic cell fluid, they will turn red.

In addition, sunlight will also affect the yellowing of leaves. , Under normal circumstances, the location of the top of the mountain is better, so if it grows in a sunny place, the leaves will turn red in advance. The sunlight at the foot of the mountain will be worse, so the discoloration will be slightly delayed.
