2-Step Guide To Removing The Moss Growing On Your Garden's Decorative Rocks

by Claude Walters

If you use decorative rocks as a way to add texture and visual appeal to your home's landscape, you may be perturbed to see that moss has started growing on them. If this is the case, use the following guide for safely removing the moss growing on your decorative rocks.

Step 1:  Sweep the Rocks

The first step in removing the moss on your rocks is sweeping off as much of the loose growth and dirt as possible before going on to the next step. Doing so not only makes it easier to see where the roots are embedded, but it also clears the way so that the cleaning solution can soak into the cracks and pores of the rocks' surfaces.

If your rocks are small enough to lift without straining yourself, move them to your driveway or sidewalk first so you can easily sweep their surfaces. Then, use a whisk broom or stiff paintbrush to brush away the dirt and moss cover. Once you have removed as much as you are able, go on to the next step.

Step 2:  Wash the Surfaces with Vinegar

Now that you have gotten most of the moss and dirt off of the rocks, it is time to clean them using a solution made of water and white distilled vinegar. The vinegar helps remove the moss growth by killing the roots embedded deep within the stone. It also removes the green and brown stains left behind by the moss that are marring the appearance of your rocks.

Mix equal parts of water and vinegar in a plastic spray bottle, and then liberally spray the rocks. Let the solution soak into the stones for a few hours. If possible, place the rocks in direct sunlight to help with the action of the vinegar's acetic acid. Because moss grows in shaded areas to avoid the sun, putting it in the light will help burn up the roots more quickly.

After you have allowed the vinegar to work, use a stiff brush to scrub the surfaces. Then, rinse them off with a garden hose with the nozzle set on a high pressure stream to facilitate the removal of the cleaner and dead roots.

Using the steps above can help you safely remove the moss on your rocks without damaging or staining them. However, if you find any that are worn or damaged, contact a landscape material supplier to see if they have any decorative rocks that match or complement your existing ones.
