Autumn begins the changing of the leaves and New England seems to have the best. Leaf pigments, length of night and weather affect the color. Each leaf contains a certain amount of anthocyanins that act like a sunscreen and once the chlorophyll begins to break down, photosynthesis slows. This process retards the absorption of light and excess light damages the leaves. Researchers determined that nutrient-poor leaves, low in nitrogen, causes the intense red color of sugar maple leaves. The peak foliage dates for Maine are Oct. 1-21, with New Hampshire offering displays from Sept. 28 through Oct. 21. Vermont’s best viewing times are Oct. 5-28. The Farmer’s Almanac has designated the peak times in Louisiana from Nov. 2-11.
