Look out your window. See that in the trees? The colors of autumn are dominating the Missouri landscape.
Watching a sea of green trees transform to the reds, greens, oranges and yellows of autumn seems like magic. But it’s not hocus-pocus in the woods. The trees are just getting ready for winter.
Shedding leaves allows trees to conserve water during the dry months of winter. And should the tender leaves remain, they would freeze. So most of our trees deal with winter weather by shedding their leaves in fall and growing new ones again in spring.
As autumn days get shorter, other colors replace the greens in tree leaves. Many of the leaf’s chemicals and nutrients move into the tree trunk. The veins that carry the tree’s food in and out of the leaf gradually close, and the base of each leaf is sealed. Chlorophyll is the pigment that makes the greens appear. The green leaf begins to fade when the sealed veins don’t allow the leaf to replace its chlorophyll. Then the yellow, orange and brown pigments already in the leaves shine through.
Leaves of shrubs and trees turn color in October and are usually shed by November. If fall days are warm and sunny with cool nights, the colors will be at their brightest. If heavy frosts persist, they’ll be dull and fade quickly.
