Do you have areas of moss growing on your asphalt driveway? If so, it's time to eliminate the moss once and for all. Here's how:

Removing the Moss

Removing the moss is fairly easy. You simply need to use a flat blade spade to scrape it off of the driveway. Press with enough pressure to scrape all of the moss away, as well as the soil and debris that the moss had rooted in.

Now, take a quick trip to your local home improvement store and pick up some herbicide for moss. Look for a brand that is metal-sulfate based and is safe for use on asphalt surfaces. Not all formulas are meant for use on asphalt and could cause the surface to become discolored.

Treat the areas where the moss had grown with the herbicide. Use enough to saturate the area so that it seeps into the crevices and kills all of the moss spores. Let the herbicide sit for about 24 hours before continuing to the preventative steps.

Note: Don't overdo it with the herbicide or you could damage the plants around your driveway. Follow the instructions on the container and only use it on the moss-troubled area.

Preventing New Moss Growth

You will need to complete regular inspections of your driveway. After rain has passed, go out and look for areas that are holding water. Check your downspouts and gutters to be sure they aren't creating puddles on the driveway. Also, watch as your sprinkler system is working or just after it finishes for areas that are saturating the driveway and leaving water behind. You don't want any puddling on the driveway because that moisture is exactly what moss needs to thrive.

Fix gutters and downspouts that are leaking onto the driveway, adjust the sprinkler heads so they no longer saturate that part of the driveway and have any dips in the driveway repaired so that there are no areas for the water to sit after a rain.

Trim back the trees, bushes, and shrubs that are shading your driveway. Excessive shade is another reason that moss is able to grow.

Take the time to sweep dirt and debris off of your driveway from time to time. If soil is constantly an issue, install trim around your driveway to keep the dirt from washing onto the driveway while it's raining.
