Stone walkway turning brown

Landscaping

The answer to 'stone walkway turning brown' is that the most common causes are mold, mildew, or algae growth on the stone surface. This can happen when the stones are frequently wet, don't get enough sun exposure, or haven't been properly sealed and maintained.

Some common symptoms include discoloration, slippery or slimy surface, and an overall dingy or dirty appearance. To fix this, you'll need to clean the stones thoroughly, treat any existing growth, and then seal the walkway to prevent future issues.
