Where does moss grow?

Moss mainly grows in shady areas where there is an abundance of moisture. As a general rule, moss mostly grows on the northern side of trees in the northern hemisphere, while it grows mainly on the southern side of trees in the southern hemisphere.

Because moss is not a vascular plant capable of moving water throughout its structures, it needs more water than other types of plants and must rely on moisture from the surfaces it lives on to sustain itself. Moisture is more prevalent on the shady side of a tree, fallen log, rock or other structure, which is why moss grows more abundantly there.
