Lawn and Garden — FAQ
What makes a rotary edger better than a string trimmer for lawn edges?
Rotary edgers create cleaner, more defined edges that last longer. The steel blade cuts through grass roots and soil, creating a physical barrier that prevents grass from spreading into beds. String trimmers merely shred grass tips, requiring weekly maintenance.
Can manual rotary edgers cut through tough sod and clay soil?
Quality manual edgers with sharp blades and sufficient weight (4+ lbs) can cut through most sod and moderate clay. Pre-moistening hard soil helps. For rocky or extremely compacted soil, consider edging after rain or using a spade to establish the initial cut.
How often should I sharpen or replace the edger blade?
Sharpen the blade after every 1,000 linear feet of edging or when you notice tearing instead of cutting. Most homeowners need to sharpen once per season. Replace the blade when sharpening no longer restores a clean edge—typically every 3-5 years with normal use.
What's the ideal handle length for my height?
Users under 5'6" prefer 48-56 inch handles. Those 5'7" to 6'0" work best with 56-66 inch handles. Taller users over 6'1" need 66+ inches to maintain upright posture. Adjustable handles offer the best versatility for shared tools.
Are dual-wheel edgers worth the extra cost?
Dual-wheel designs provide superior stability along straight runs and sidewalks, reducing blade wander by 40-60%. For properties with extensive straight edging, the upgrade pays for itself in time saved and edge quality. Single wheels suffice for small yards with mostly curved borders.
Can I use a rotary edger to install new flower bed borders?
Yes, but establish the outline with a garden hose first. Walk the edger along the line, applying firm downward pressure to cut through sod. Make 2-3 passes for deeper cuts, then remove the sod strip. For beds wider than 4 inches, use a spade to remove soil after edging.
