Moss-covered asphalt driveway

Asked June 10, 2018, 2:11 PM EDT

Hi. We have a 400 yard long asphalt driveway that courses through hilly and wooded terrain. The past 3-4 years have been wetter than previous years. In the shade and lingering dampness, moss has gone from being an interesting biological phenomenon to an eyesore that may even be contributing to surface deterioration. We have a well near a part of the drive closer to the house. What are some DIY suggestions for effective moss mitigation? Thanks.

We don't have research or expertise on this particular problem. There are products on the market that kill moss (usually for roofs or decks.)

Bearing in mind that the moss is living on the "soil" created by particles building up in the crevices of the asphalt over the years, you may be able to get rid of the moss and also clean up its growing medium, by cleaning the drive with a pressure-washer.
