What “cheap” actually means here
Edging a lawn can cost you $0 or it can cost you $150, and the finish line looks almost the same either way if you’re not chasing a landscaping-crew look. The real question isn’t “what’s the cheapest tool” but “what’s the cheapest tool that won’t make this job miserable twice a month.” A $12 half-moon edger does the same cut as a $300 electric edger. It just takes 20x longer and leaves your forearms wrecked after 40 feet of bed line. So the cheap way to edge a lawn is really a decision about where you want to spend: money up front or time every two weeks.
Manual edging: the actual cheap option
A manual half-moon edger (sometimes called a step edger) is a flat, curved steel blade on a stick. You step on it like a shovel and rock it to slice a clean line between lawn and bed or walkway. These run $15-$30 and never need gas, batteries, or charging. For a small yard, under about 1,500 square feet of edge line total (think a typical quarter-acre suburban lot with a few beds), this is genuinely the best value, not just the cheapest.
The catch: it’s a workout. You’re putting your body weight through your foot into packed soil, and if your soil has clay or roots, every few inches you’ll hit resistance that makes you reposition and stomp again. Expect 45-60 minutes for a yard that an electric edger would finish in 10. It also only cuts a vertical trench, it doesn’t clean out the loosened soil, so you’ll want a flat spade or hoe to scoop debris after.
A manual rotary edger with a star-wheel blade (you push it like a mini lawnmower) is the other cheap option, usually $25-$40. It’s faster than the half-moon on long straight runs like sidewalks but struggles on curved bed lines and gets twitchy in thick grass. If your yard is mostly straight sidewalk edges, this beats the half-moon. If it’s curvy garden beds, the half-moon wins.
The string trimmer trick: zero extra cost
If you already own a string trimmer, you likely already own an edger. Most trimmers let you rotate the head 90 degrees so the string spins vertically instead of horizontally. Run it along the edge of the lawn and it’ll chew a rough line. This costs nothing beyond what you already spend on trimmer line, which is maybe $5 a season.
It’s not a clean cut, more of a ragged scalp line, and it throws grass clippings and dirt everywhere, including on your shoes and shins. It also wears string fast since you’re grinding it against soil and sometimes concrete. For someone who just wants the lawn to look tidy from the street and doesn’t care about a crisp architectural edge, this is the actual cheapest method because the tool cost is already sunk. For someone who wants the sharp line you see around professionally maintained lawns, it won’t get you there.
When a cheap electric edger beats manual
Corded electric edgers start around $45-$70 and are worth considering once your total edge length gets past that 1,500 square foot mark, or if you have more than, say, 100 feet of combined walkway and driveway edge. At that volume, manual edging starts eating 90+ minutes every two weeks in growing season, and the math on your time flips. The downside is obvious: you need an outlet within extension cord range, and dragging a cord around tree beds and corners is its own annoyance. Battery edgers remove the cord problem but jump to $100-$180, and that’s where “cheap” stops applying.
If you’re shopping this route, look at corded electric lawn edgers before battery models. You lose almost nothing in cutting performance and save real money, assuming your yard isn’t a cord-management nightmare.
Cost and time comparison
| Method | Upfront cost | Time for average yard | Edge quality | Best for |
|---|---|---|---|---|
| Half-moon manual edger | $15-$30 | 45-60 min | Clean, sharp | Small yards, curved beds |
| Rotary manual edger | $25-$40 | 30-40 min | Clean on straight runs | Sidewalks, driveways |
| String trimmer (edge mode) | $0 (if owned) | 15-20 min | Rough, ragged | Low-effort upkeep |
| Corded electric edger | $45-$70 | 10-15 min | Clean, consistent | Larger yards, long edges |
| Battery electric edger | $100-$180 | 10-15 min | Clean, consistent | No outlet access, frequent use |
Other ways to keep it cheap
Skip buying a dedicated edging spade if you already own a flat shovel. It won’t make as crisp a cut as a true half-moon edger, but for occasional touch-ups it’s fine. Also skip the pre-emergent “edging guard” strips sold for garden beds. They cost $20-$40 per roll and don’t actually reduce how often you need to re-edge, they just mark where the line should be, which you can do by eye after the first pass anyway.
If you want a sharper manual edger without buying a specialty tool, a basic garden edging shears set handles touch-up trims along already-cut lines for under $20, which stretches the time between full edging sessions. It won’t cut a new line through sod, but it keeps an existing line looking sharp for weeks longer.
The honest bottom line on cost: for most home lawns, a $20 half-moon edger and 45 minutes every other week beats any powered tool on pure dollars. Power tools earn their keep only when your edge length or your patience runs out first.
