Natural Way to Kill Moss

Updated March 23, 2017

Unsightly moss growing on the side of your house, in between pavement stones and along sidewalks can be a difficult fungus to kill naturally. Moss typically grows in areas that are void of sunlight but abundant in moisture. Using harsh and toxic chemicals to kill moss outside of your home can kill surrounding patches of grass, and can also stain surfaces. Conquer and destroy moss naturally using gentle household items and a little force.

Pressure Washer

Use a simple pressure washer on surfaces such as sidewalks, driveways and directly on your house to blast moss away. Plain hot water will effectively remove the moss and adding solutions such as vinegar to the water tank will assist you in keeping moss at bay.

Try adding basic baking soda to your water tank or you could apply the solution directly to the mossy area, scrub and then blast with your pressure washer. Use your pressure washer on the areas at least once a year in drier climates of the country and quarterly if you live in tropical area.

Hard Surface Solution

Remove pesky clinging moss on hard surfaces using a watering can and a few products from home.

Dissolve 0.454kg. salt in an equal amount of extremely hot water. Add 1 gallon malt vinegar, two squirts of dish washing liquid and 4 tbsp lemon juice. Pour the mixture into your watering can and apply liberally to mossy areas. This mixture may affect other surrounding greenery so cover or protect these areas before applying. Use this solution on a day when no rain is expected and do not rinse after applying.


Killing moss on your lawn is tricky because most moss killing agents wipe out greenery too. According to the Northwest Coalition for Alternatives to Pesticides (NCAP) the presence of moss means that your lawn is experiencing stress or is unhealthy.

One of the best ways to remove the moss immediately from lawns is to use a hard rake to remove mechanically. Bag and throw away the removed moss. Prune trees and areas around the affected areas so that moss does not return.

One reason moss grows on lawns is because the grass is nitrogen deficient. Prevent moss from forming using simple organic fertiliser. Use nutrients and minerals, including nitrogen, for a healthy, moss free lawn. The NCAP suggests applying organic fertiliser to your lawn because it releases nutrients slowly and there is less run off.
