If you’ve ever admired a well-manicured lawn with crisp, defined borders, chances are you’ve noticed the results of edging. Edging is the secret weapon that separates a tidy yard from an exceptional one. Whether you’re trying to boost curb appeal, create a more polished outdoor space, or simply keep grass from spilling over onto sidewalks and garden beds, learning how to edge a lawn is an essential skill for any homeowner or renter.
From homes in Charlotte, NC to homes in Phoenix, AZ, clean lawn edges can elevate any property’s exterior. In this Redfin article, we’ll walk you through what edging is, why it matters, and how to edge your lawn like a pro using the right tools and techniques.
What is lawn edging?
Lawn edging is the process of trimming the edges of your grass to create a sharp boundary between your lawn and adjacent surfaces—like sidewalks, driveways, flower beds, or patios. It gives your yard a clean, organized appearance and helps prevent grass from encroaching into areas where it doesn’t belong.

Expert-recommended tools and techniques
Use a power edger for clean lines
“For the cleanest lawn edges, a power edger is your best friend,” recommends AZ Citiscapes. “Follow the natural lines of your lawn and use the height attachment for consistent depth. Avoid relying on a weed wacker, which can create uneven cuts and damage the grass. For tricky layouts or large yards, bringing in a pro can ensure a flawless finish and save you serious time.”
Steel blades create the sharpest edges
“The best lawn edges come from a steel-bladed power edger,” notes Yardly. “It cuts through grass, thatch, and soil with a clean gap between the turf and hardscaping. Depending on your soil, the results vary—thicker bases give that sharp, cake-slice look, while thinner ones show more thatch. Either way, a pro touch boosts curb appeal and often inspires the whole block to step up.”
Quality tools and regular maintenance matter
“Using quality tools like a Stihl edger makes all the difference for clean, professional lawn edges,” says Torres Lawn & Landscaping. “The longer you wait, the more time it takes—overgrown edges can turn into a 2–3 hour job. During the summer, edge twice a month to keep things sharp. If it gets overwhelming, hiring a pro ensures your lawn stays in great shape year-round.”
Slow and steady wins the edge
“Rushing is a common mistake—take your time for consistent results,” says RP Lawn Services. “Sharpening your blades regularly keeps edges sharp and tools working efficiently. Edge once a month during the growing season to keep things looking clean.”
Step-by-step: How to edge a lawn
Step 1: Plan your edging line
Start by identifying the areas you want to edge. This typically includes:
- Along sidewalks and driveways
- Around garden beds
- Bordering patios or walkways
Use a garden hose or string as a flexible guide to outline your desired edge. This is especially helpful for creating smooth, curved lines.
Step 2: Choose the right day
Edging is easiest when the soil is slightly moist. Avoid edging when the ground is bone dry or soggy—both conditions make clean cuts harder to achieve.
Step 3: Cut the edge
For manual tools:
- Position your half-moon edger or spade straight up against your line.
- Step down firmly to cut into the soil and grass, about 2–3 inches deep.
- Wiggle the tool slightly to loosen the sod, then lift and remove it.
- Repeat along the entire border, keeping a consistent depth.
For powered edgers:
- Follow the tool’s instructions and slowly guide it along your edge line.
- Keep a steady hand and consistent speed.
- Let the blade do the work—no need to force it.
Step 4: Remove excess sod
Use your hands or a rake to remove the clumps of grass and soil you’ve dug up. For a polished look, use garden shears to trim any uneven bits.
Step 5: Clean up and maintain
- Sweep or blow away leftover clippings and soil from sidewalks and driveways.
- Water the newly cut edge lightly to help the grass recover.
- Re-edge every 2–4 weeks during the growing season to maintain sharp borders.
Pro tips for lawn edging success
- Be consistent: Regular edging makes future upkeep quicker and easier.
- Use mulch or brick edging around flower beds to reduce the need for frequent edging.
- Combine with mowing: Edge your lawn on the same day you mow for a seamless finish.
- Mark sprinkler lines before edging to avoid damage.
Expert tips for manual edging and personal techniques
Use a half-moon edger or string trimmer consistently
“A sharp half-moon edger or vertical string trimmer is essential for crisp, consistent lawn edges,” advises GleeWork. “Edge every one to two weeks to prevent overgrowth and maintain that polished curb appeal. A lot of people overlook regular maintenance—installing permanent materials like steel or brick helps keep your edges looking sharp longer.”
Turn your trimmer vertically for clean results
“To trim your lawn’s edge, turn your line trimmer vertically and walk it along the edge for a clean, defined cut,” recommends Southland SOD Farms. “We’ve grown sod for over 40 years and this simple technique—paired with clean tools—makes a big difference. Whether you’re edging your driveway or defining a bed, this method works across the board.”
Common mistakes when edging your lawn
Even with the right tools and techniques, there are a few common missteps that can throw off your results. Here are some key mistakes to watch out for:
- Cutting too deep: This can weaken or damage the grass’s root system, leading to brown edges or patchy growth.
- Using dull or dirty tools: Dull blades tear rather than slice, which stresses the grass and can introduce disease. Always clean and sharpen your tools regularly.
- Edging after mulching: Doing this in reverse order can create a mess and reduce the sharpness of your lines. Edge first, then mulch.
- Inconsistent edging: Irregular timing can lead to overgrowth and make it harder to maintain a clean look. Aim for a consistent schedule during the growing season.
- Incorrect technique with string trimmers: Holding your trimmer at the wrong angle can create jagged, uneven edges. Adjust your grip and positioning to cut vertically.
Incorporating expert insights, like those below, can help avoid these pitfalls
Avoid deep cuts and use guides
“An edging guide can be a game changer when it comes to maintaining straight, consistent lines,” says Kelstone Contracting. “Be careful not to dig too deep, especially around tight curves. We often suggest brick or metal edging for a clean finish and less frequent touch-ups. For larger or detailed landscapes, pros can handle the job more efficiently.”
Prioritize shallow cuts and clean tools
“A shallow, precise edge protects your lawn’s root system while creating that defined look,” explains MOOWY. “Clean, sharp tools are key—dirty blades spread disease and make cutting harder. A clean border boosts curb appeal and helps control weed spread by forming a natural barrier.”
Use simple tools and recycle sod
“I swear by a garden spade over those pricey edgers—they’re simple, strong, and super effective,” shares Mom Versus the World. “I edge before laying mulch, and touch it up in midsummer if needed. If you cut clean sod, save it. I reuse pieces to patch worn areas along my pavers, just water them daily for two weeks. Bonus tip—don’t edge after mulching, and for the love of grass, wear goggles.”

Frequently asked questions about edging a lawn
1. How often should I edge my lawn?
Most experts recommend edging every 2–4 weeks during the growing season, depending on how fast your grass grows. If you’re using mulch or have permanent edging installed, you might be able to go longer between sessions.
2. What tool is best for beginners?
A half-moon edger or a string trimmer with an edging guide is beginner-friendly and effective for small to medium lawns. For large yards or tougher soil, a power edger is worth the investment.
3. Should I edge before or after mowing?
You can do either, but edging after mowing lets you clean up any grass that’s spilled over and get a more precise cut.
4. Can I edge my lawn with a weed wacker?
Yes, but be careful—weed wackers can be tricky to control and may lead to uneven lines if not used properly. Always hold it vertically and walk slowly along the edge.
5. Do I need to install permanent edging materials?
Not necessarily. A clean, natural trench cut can hold mulch in place and define your bed. But materials like metal or brick can reduce long-term maintenance and add a decorative touch.
