The answer to 'how to install stone walkway' is to carefully plan the layout, prepare the ground, and properly install the stones to create a durable and attractive pathway. Start by measuring the desired walkway area and sketching out the design. Excavate the ground to a depth of 4-6 inches, compact the soil, and lay a 2-3 inch base of crushed gravel or stone dust. Arrange the stones in your desired pattern, leaving 1/4 to 1/2 inch gaps between them. Use a rubber mallet to level the stones and fill the gaps with sand or fine gravel. Finally, add edging along the sides to keep the stones in place and prevent weeds.
Installing a stone walkway requires some physical labor but can be a rewarding DIY project. However, for larger or more complex designs, it's best to consult a professional landscaper who can ensure the walkway is properly installed and will last for years.
