Lawn edging creates a clean, vertical line separating turf from non-turf areas (sidewalks, driveways, or garden beds). This practice provides a high-definition boundary, instantly improving the overall aesthetic appeal of your landscape. Edging maintains the intended perimeter, preventing grass from creeping into adjacent areas.
Standard Edging Frequency
Edging frequency depends on the desired crispness and the activity of the growing season. During the peak season (mid-spring through mid-summer), hard edges along concrete or asphalt should be addressed weekly or with every mow to maintain a sharp appearance. This frequent maintenance prevents grass blades from growing sideways and blurring the line.
For a slightly more relaxed look, edging every one to two weeks is sufficient during periods of rapid growth. Letting the grass overgrow requires significantly more effort to re-establish the boundary. For soft edges, such as those bordering flower beds or mulch, a maintenance schedule of every two to four weeks is often sufficient to keep the area neat.
Monthly edging is the minimum for maintenance, practical only during slower growth periods. The most consistent recommendation is to align edging with your mowing schedule, performing the task with every pass for maximum definition, or at least every second or third mow.
Factors Influencing Your Edging Schedule
Lawn conditions and grass type are the primary variables influencing edging frequency. Runner-type grasses, which spread aggressively through stolons and rhizomes, require more attention. Warm-season grasses like Bermuda and Zoysia are aggressive runners that require weekly attention during peak summer heat because their lateral growth rapidly invades adjacent areas.
In contrast, clump-forming grasses, such as Fescue or Kentucky Bluegrass, spread primarily from the crown of the plant. These varieties pose a much lower threat of encroachment and may only need edging every three to four weeks, or even every six to eight weeks, depending on the season.
Growth speed is heavily influenced by environmental factors. Frequency must increase during mid-spring and early summer when optimal temperatures and abundant moisture lead to the fastest growth rates. Conversely, the schedule can be reduced to monthly or stopped entirely during the dormant season. Heavy rainfall or increased irrigation also accelerates growth, demanding a shorter interval between sessions.
Essential Edging Tools and Techniques
The choice of tool affects the ease and permanence of the edge. A string trimmer (weed wacker or whipper snipper) is the most common tool for light maintenance and quick touch-ups after mowing. To create a clean edge, the operator must hold the tool vertically, rotating the cutting line perpendicular to the ground. This provides a vertical cut that cleanly shaves the grass overhanging the hard surface.
For establishing a deep, permanent line, a dedicated blade edger or a manual tool like a half-moon edger is more effective. These tools use a spinning metal blade or a sharp spade to cut a shallow trench, establishing a defined boundary. A dedicated edger provides a precise, 90-degree angle cut, which is superior for creating a lasting, shadow-line effect.
Regardless of the tool, the technique must focus on maintaining a consistent, vertical angle to achieve a sharp separation. Work slowly, especially around curves, to ensure the cut is precise and uniform. Clearing debris and wearing appropriate safety gear are basic preparatory steps for an effective session.
