Will the maple leaves turn red after the first frost?
Maple leaves usually turn red in autumn.
Whether the maple leaves will turn red after the first frost is a question that many friends have. According to previous data, maple leaves gradually turn red because of the autumn temperature. Although autumn in the north is in August-10, it usually doesn't really enter autumn until the end of September, so maple leaves usually don't bloom until September-10. When autumn comes, the days get shorter and the nights get longer, which makes the trees begin to shed their leaves. Trees don't produce a lot of chlorophyll as in spring and summer before falling leaves, and the existing pigments, such as chlorophyll, will gradually decompose. In this way, with the gradual reduction of chlorophyll content, the colors of other pigments will gradually appear on the leaves, so the leaves will show yellow, red and other colors.
