Shorter days and cooler nights start a precise clockwork of physical and chemical interactions within leaf cells bringing forests ablaze with color as they prepare for winter dormancy. In response to certain environmental stimuli, leaf pigments begin to reveal themselves in the leaves of Georgia’s deciduous trees. The amount of pigments in trees depends on the tree species, soil composition, and other environmental components.

Lowering temperatures and adequate rainfall has led to the beginning of foliage color change in NW GA.

The past week has been cool and sunny with a little rain, allowing many of the trees to slowly progress with color change. Areas with high concentrations of blackgum and sourwood are currently showing the most vivid colors providing differing shades of red and orange. Sassafras is also beginning to show a variety of colors including yellow, orange and red. 

Foliage color change is steadily progressing and is most visible in areas above 2000 feet. Sourwood and blackgum continue to provide a majority of the red patches seen from overlooks and ridges. Hickory and poplar have made the most significant changes over the past week as they are beginning to display a mix of vivid yellows, golds, and browns.
