stone walkway yellowing

Landscaping

The answer to 'stone walkway yellowing' is that the most common cause is mineral deposits or efflorescence on the surface of the stone. This can happen when water evaporates from the stone, leaving behind salts and minerals that create a yellow or white hazy appearance. Other potential causes include dirt, mold, or mildew buildup on the surface.

The symptoms of a yellowing stone walkway include a dull, hazy, or discolored appearance compared to the original stone color. In some cases, you may also see white or yellow crystalline deposits on the surface.
