Paving stones include a distinctive and elegant appearance to the hardscape areas of the landscape. It’s disappointing when you look out at your lovely patterned pavers and see moss covering the stones. Moss can also be a hazard, because it turns a walkway to a slippery mess when the moss is moist. In case your pavers are in a moist, shady place, moss growth is unavoidable. Eliminate the moss and slow its recurrence.
Shed some light on the area. Moss will not grow in sunny places, so trimming overhanging tree or tree limbs that shade the pavers are going to keep the moss away.
Pressure wash the stones. Use the pressure washer at a low angle to blast the moss away. Examine the spray in a small spot at first to make sure it will not damage the pavers. Don’t linger in one spot; spray the moss-covered place quickly and proceed.
Scrub the moss away with a scrub brush. The moss should scrub off with water in case you do not want to work with a pressure washer. Wash the area with a hose or a bucket of water to clean the loosened moss in the stones.
Spray the pavers with a solution of equal parts water and chlorine bleach annually to help stop the moss from returning immediately. Examine the solution in a small area first to make sure it doesn’t discolor the rocks. Wet the stones for 30 seconds. Wash the bleach solution in the stones with clean water.
