What Is Lichen Removal & Control?
Lichen is a composite organism made of fungus and algae living together. It appears as crusty growth in orange, grey, green, or black colors. Unlike moss, lichen growth is very slow but can persist for many years.
Causes & Triggers
Lichen grows in clean air areas exposed to moisture and established on hard surfaces. It thrives on brick, stone, and concrete. Slow growth means lichen-covered properties are often older or long-neglected.
