Homeowners may use a garden border to outline a flower bed, offer protection for plants against possible damage from a lawn mower or weedeater, or to provide a softening edge between the lawn or walkway and the garden. A garden border can be created from vegetation or from natural or artificial landscape material.
Ground cover like alyssum or candytuft will soften the edge between the garden bed and the lawn, walkway or driveway. Colorful low-growing perennial flowers like coreopsis that bloom almost all summer can make a garden border attractive--to you and to butterflies. Flowers like lavender or geranium planted along the border of a vegetable garden deters cats, while providing a distinctive border.
Raised Landscape Material
Rocks between 6 and 18 inches tall butted end-to-end, or a low wall of stacked flagstones, can create a border to withstand the biting string of a weedeater. Bricks can be mortared and stacked two rows tall to create a mini retaining wall. Bricks can also be set halfway into the ground and on a 45-degree angle, with one brick leaning against the next, for a zigzag appearance. Concrete curbing can be laid, and even colored and stamped with a stencil to make the concrete look like brick or cobblestone.
When tugging on a garden hose, you can rely on a sturdy, raised garden border to keep the hose away from tender plants.
Ground-Level Landscape Material
A garden border that is level with the ground provides a breaking point between the garden and the lawn, but it also provides a surface on which the wheel of the lawn mower can ride. Options for ground-level landscape material include bricks laid with the long sides together; flagstones or stepping stones; vinyl strips specifically designed for garden use; cobblestones; or pebbles.
