Does the coloring stain sidewalks, driveways or clothes?
Mulch colorants are similar to a wood stain. When dry, it bonds to the wood surface – but until properly dried, the color can rub off and bond to the surface it dries on. Before laying mulch that might still be wet on a driveway or sidewalk, lay down a tarp. It’s a good idea to water the driveway or sidewalk before and after dumping the mulch so that any color that does get on the surface has less chance to dry. Then, while it is still wet, use soap, water and a broom to brush up any remaining color.
