How to Manage a Mossy Deck
Although moss gives a beautiful aesthetic to a garden landscape, it isn’t so attractive when it covers the deck. Since moss does not have any roots, it may develop freely on sidewalks, decks and roofing. Moss also rises at a rapid pace, quickly covering a great portion of your deck if it is not eliminated. This is dangerous as it may leave the deck slippery. Eliminating the moss is simply the initial step in dealing with it. You also must take action to maintain the moss from coming back.
Remove any furniture, toys or barbecue equipment in the deck before taking measures to eliminate the moss.
Mix half of a gallon of hot water and half a gallon of sodium hypochlorite (chlorine bleach) at a garden sprayer. Spray straight over the moss on your deck so that the moss is soaked entirely with the option. Wait 30 seconds before continuing.
Dip a brush in a bucket of water and then bathe the moss loose. You will not require much elbow grease, as the moss will appear without much work.
Clean the deck with a power washer. This will eliminate any moss that still stays on the deck, in addition to the bleach option you implemented earlier.
Trim back any branches that are preventing sunlight from reaching your own deck. Moderate to intense shade offers moss with the states it should grow. Adding sunlight makes the deck less vulnerable to the moss.
Sweep your deck often during the autumn months when the leaves begin to fall from the trees. The University of Minnesota Extension recommends removing this kind of organic material in order to decrease the chances of moss returning to your deck.
