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.
Dormancy. Lilies grown as houseplants, such as the peace lily, need a period of dormancy each year. During this time, the leaves turn yellow, the plant produces no new flower buds, and the lily can look bedraggled, like it is dying.This is natural and can happen during the winter or when you repot a houseplant lily.ater. Too much or too little of this natural resource can cause leaf yellowing. If you notice yellow leaves on an indoor or outdoor lily, touch the soil. If the soil feels dry and dusty, you're probably not watering the plant enough. If the soil feels slushy or boggy, you're giving the lily far too much water.
