Edging a flower bed with stone helps to define the space and add contrast to the landscape. There are a variety of tough and durable stones that can be used to edge the garden. Wide stones like flagstone and slate are ideal to create stacked edges and are helpful along sloped gardens for leveling the land. Smaller stones like river rocks and pebbles create a low-maintenance, classic design.
River rocks are a type of stone to use for edging a flower bed and, as their name suggests, can be found lining a river or stream. These multicolored rocks have earthen hues that complement a garden. River rocks come in many sizes and shapes to create a large or small edging design. River rocks can be stacked along the flower bed or spread out to create a wide edging. When wet, the color of the river rocks deepens to create a contrasting design.
Slate is a rich, flat and stackable stone that comes in deep gray, blue and black. There are many sizes, and slate and can be broken to form smaller pieces to help fill in awkward spaces along the flower bed. To create the slate edge, lay the widest pieces on the bottom of the soil with smaller pieces on top. The small pieces can also be used to level larger slate stones and to help fill in small gaps among the edge. As you stack them along the flower bed, angle the slate pieces so as they are flush with the rest of the stones. Choosing pieces of slate that are similar in size will help create a cohesive design. Slate is ideal to help with water runoff and drainage, especially on a sloped bed, because of their ability to be stacked together for a snug fit.
Field stones are larger stone that, as the name indicates, can be found naturally in fields like those on farms. Their colors are similar to river rocks, earthy and natural, but the size is significantly larger. Field stones create attractive edging around the flower bed and are easy to move around for different designs. Many field stones also have a flat side to make it easy to situate along the landscape. For larger field stones, and to create an even edge, bury part of the stone in the soil. They can be situated side-by-side for a simple flower bed edge, or stacked together to create a miniature rock wall along the garden.
Bricks are made in a variety of colors and shades for elegant flower bed edging. These sturdy and long-lasting stones have a classic rectangular shape and can be nestled along the flower bed side-by-side or stacked to create a high edge along the bed. Bricks can also be partially buried into the soil to create an edge that is flush with the rest of the garden.
