Landscaping slopes is a challenging task because erosion is such a major problem. Plant flower beds to beautify the landscape and prevent soil erosion on the slope. Once the flower bed is installed, you may determine that the slope is still missing a finishing touch. Edging creates a border to frame the flower bed, making it appear complete and more defined. Stones are natural objects that blend with other outdoor elements and are easy to find for little to no cost to the homeowner. The major problem with edging slopes with stones is ensuring that the stones stay in place.
Lay out the area for the border with a garden hose, rope or landscape paint.
Measure a few of the stones to determine the average height of your stones.
Dig out a trench for the edging area; the trench depth should be half the average height of the stones.
Place the larger stones at the base of the slope and progress to smaller stones as you work your way up.
Lay each stone on the broadest side to ensure that it will sit properly.
Dig out the area for a specific stone as needed for stones that are taller than the average figure you used to dig the trench. Add fill dirt to compensate for shorter stones.
Fill in the spaces around each stone with dirt as you fill in the edging so that at least half of the stone is covered. Pack the dirt well to ensure that the stone is anchored in the ground.
Pack smaller stones to fill in the gaps between larger stones.
