How to Edge Your Lawn (2024)

A lawn can be your home's a masterpiece, and edging it is the final step in setting it apart from the average. Providing your lawn with a sharp edge gives it definition that makes your beloved lawn pop. Read on to learn how to edge a lawn like a pro with the proper tools.

Do You Have to Edge Your Lawn?

No. Whether or not you edge it has no impact on lawn health; from the perspective of lawn care, it's purely an aesthetic practice. Most homeowners don't edge their lawns; where the lawn abuts a driveway, flower bed, etc., they're content to trim grass that the lawnmower can't reach using a string trimmer.

To edge a lawn requires a lot of work (although, for lovers of well-manicured grass, the task is worth the work), even though the process, itself is easy. It isn't a job you can do once and then forget about. Once you've established an edge, you must maintain it. Homeowners who prefer low-maintenance will seek alternatives. A compromise is to lay hardscape edging: It provides definition but must be done only once.

While creating an edge doesn't improve lawn health, it does have practical benefits. Not only does it keep rhizomes from invading mulched beds, but it also works the other way: It keeps the mulch from spilling out onto your lawn.

When to Edge Your Lawn

To establish an edge between a lawn and flower bed, late spring is a great time for the job (although the operation can be performed any time the ground isn't frozen), because the ground will have dried out by then, making the soil easier to work with.

Plus, many people like to get their beds mulched before summer, when weeds grow most vigorously. Once you get your trench dug, you can apply mulch to the bed and achieve a clean look. If you reverse the process, you'll inevitably spill some soil onto your mulch.

Rhizomes will bridge the trench and invade your bed at some point during the summer. At this point, you'll have to remove the rhizomes and "touch up" your edge. Because doing so is messy, it's hard to avoid getting some soil on your mulch, but try not to.

Before Getting Started

Check on any utility lines, etc. that may exist where you'll be digging. Put on standard garden wear: heavy work boots, garden gloves, etc.

For equipment, first choose between power and manual tools. While there are power tools called "edgers" that some may prefer to use for big jobs, in this project, we'll be using a manual tool. For manual tools, choose between a spade and a half-moon edger. We picked the latter because it's specifically designed for the task. A flange called a "depth guard" runs perpendicular to the unit's cutting blade and facilitates creating a uniform trench. Sharpen the blade before using it.
