Lichens of Crape Myrtle

Disease Information

Lichens

Symptoms

 A lichen is an unusual organism composed of a fungus and an alga living together in the same body. Lichens often appear as green to gray-green leafy or crusty growths on the trunks or branches of plants. Typically, they occur in abundance on plants that are declining in health or vigor. They are harmless to the plant, and are in no way responsible for the poor health of the plant. Less vigorous plants tend to be more open, increasing sunlight penetration, and subsequent lichen growth.

Management

 Controls are not necessary. Lichens will gradually disappear if the health of the plant is restored.
