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.
Insects like aphids, mealy bugs or scale feeding on the plant can also cause brown leaves and flowers. Examine the plant carefully, turning over the leaves. Insects may show up as clusters of white under leaves, on stems or around flowers.
