Autumn Foliage Color. The Process of Leaf Color Change. Leaves change color during the autumn because the amounts of pigments change as the leaves prepare to fall from the trees. All leaves gradually lose chlorophyll during the growing season, and this loss accelerates before leaf fall.
Anthracnose presents with irregular spots with darker borders on foliage. As the disease progresses, the centers of the spots disintegrate, leaving tiny holes in the leaves. Petiole rot causes foliage to yellow and then turn brown from the outer edge toward the base of the leaf. Eventually leaves wilt and fall from the plant. The base, or petiole, of the leaf softens and turn brown.
