Why is the number of fallen leaves in Guangzhou in spring (the more detailed the better) less than 300 words?

Many landscape experts said in an interview with reporters yesterday that it is normal for some trees in Guangzhou to turn yellow, wither and fall leaves in early spring, mainly because after winter, the leaves change alternately and the old leaves wither before new leaves can grow.

Huang Zhenglian, a landscape engineer at Liuhuahu Park, said that there are large areas of fallen leaves in Guangzhou every year. He said that it is normal for autumn leaves to fall in the north, but Guangzhou is located in the south and the climate is warmer. In addition to falling leaves in autumn, there will be large areas of falling leaves in early spring. "In winter, the temperature is relatively low, and there is less water in the tree. In spring, trees begin to absorb water. After the original old leaves complete their mission, they will turn yellow and dry, then fall and grow new buds again. " This is a signal that spring is coming!

According to the introduction of the Greening Department of the Municipal Bureau of Landscape Architecture, the deciduous trees in Guangzhou are mostly large-leaved banyan trees, which are planted in many road sections and parks. "Some big-leaf banyan trees are deciduous trees, and some are deciduous trees, so some big-leaf banyan trees have fallen leaves, but some big-leaf banyan trees next to them don't."
