Methods
of Moss Control
Some homeowners are interested in controlling or removing mosses
growing on their roofs, decks, sidewalks, patios, lawns, or trees
and ornamental shrubs. Mosses are viewed by some people as unattractive.
Others are concerned about possible structural damage to parts
of their property.
Moss control is generally achieved by physical removal, chemical
treatment, or a combination of these methods. These methods have
different costs, effectiveness, and potential side effects that
need to be considered. A key point is that mosses flourish under
certain environmental conditions. If you try to control mosses,
but do not address the underlying conditions that favor moss
growth, they will surely return (see Basic
Biology of Mosses).
Be cautious if you decide to attempt
chemical control. Many methods of chemical control can cause
plant or animal injury, stains, corrosion, or pollution of soil
and water (Davison and Byther, 1999).
For these reasons, chemicals should be applied according to the
label instructions. Furthermore, the effectiveness of many herbicides
against mosses is poorly known. Learn about some of the problems
and alternatives from the Washington Toxics Coalation Fact Sheet,
"Tales
from the North Side: Problems with Moss."
