Fall foliage has begun to appear across parts of Maryland, according to the Maryland Office of Tourism and the Maryland Department of Natural Resources Fall Foliage & Festival Hotline.
Some of the earliest displays of fall foliage can be found in western Maryland. Traditionally, foliage in Garrett County begins to turn around the end of September and peaks around mid-October.
Maryland's fall foliage hues usually vary from year to year, depending on Autumn temperatures, rainfall, storms, and other factors.
During the Fall season, trees release a chemical called phytochrome, which slows down chlorophyll production in preparation for winter dormancy. As the green chlorophyll recedes, foliage changes color.
The amount and acidity of tree sap also affects foliage colors. Strongly acidic sap leads to red and other brightly-colored foliage, while less acidic sap produces more yellows or softer tones.
