The answer to 'when to stone walkway' is that the best time to install a stone walkway is typically in the spring or fall when the weather is mild and dry. This allows the ground to be properly prepared and the stones to be set in place without the challenges of extreme heat, cold, or wet conditions.
Before installing a stone walkway, it's important to ensure the ground is properly graded and compacted to provide a stable foundation. This may involve excavating and leveling the area, adding a base layer of gravel or crushed stone, and tamping it down firmly. The stones can then be laid in a pattern of your choosing, with spaces between them filled with sand or small gravel to lock them in place.
