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.
Spotted, dark colors on leaves are an indication of serious problems with your plant. Plant leaves turn black for a number of reasons, including environmental factors and bacterial infections. In some cases the plant is salvageable. However, most of the problems that cause black leaves in plants are irreversible.
