Moss – Control on Walkway

Q: We have a beautiful walkway with steps of large Georgia creek rocks. They are getting moss on them and are slippery. What can I use to kill the moss without killing the plants that grow between the stones?

A: Moss is a plant after all, so killing moss while protecting nearby plants is tough. One option is to use strips of cardboard to protect plants at the edges of your stones and spray ammoniated soaps of fatty acids (Lilly Miller Moss Out! for Roofs and Walks) on the moss. Another option is to use a foam paintbrush to paint bleach diluted with water in a 1:1 ratio onto the moss. Both methods should kill moss within a few hours. The stones can then be washed off with lots of water to avoid hurting nearby plants.
