Little did I know that the yellow, orange or red coloring of tree leaves during the fall is actually something trees do to be more efficient. Instead of just shedding their green leaves during the winter, they try to prepare for the shedding by making the colors yellow, orange or red. This allows them to recycle all the valuable nutrients they had laboriously gathered and put in leaves earlier in the year to make the leaves!
So, leaves are disassembled and all the nutrients are carried from leaves to the branch to store them. But this process is tricky and these details are well illustrated in the video below.
