How to Edge a Flower Bed or Garden in 5 Easy Steps

Using a half-moon edger, face your flower bed and cut the outline of your marked shape by stepping on the tool with one or both feet and pushing your turf upward.

Depending on your soil's hardness, you may need to face the opposite way and use your edger to loosen the turf from a 45-degree angle.

You can also cut your shape with an electric, circular-bladed edge cutter. This tool helps to cut clean lines along your border. However, an electric edger only cuts 1 1/2 inches deep, so you’ll have to dig down further with a half-moon edger or spade to finish the process.

Once you’ve cut out your shape, use your hands or a shovel to dig out the loose turf at a 90-degree angle. It will come out in chunks, so you can easily toss it in your wheelbarrow. 

Next, you’ll want to trench your edge to make room for your border material.

Grab your garden rake and add 2 to 3 inches of fresh pine bark mulch to your flower beds. Spread and smooth the mulch with your rake. Pine bark mulch prevents weed growth and nourishes the soil.

Next, you’ll want to plant your flowers and shrubs a few inches away from your border. This breathing space will help with tending to your lawn and garden by allowing easier pruning and mowing. 

Lastly, give your newly planted greenery a fresh drink!

Now comes the fun part—selecting your border material. A well-defined border helps to separate grass from your flower bed. There are several border edging methods to choose from:

Trench Edging 

Grab a small shovel or garden trowel and dig out a shallow trench along the edging line. You’ll want to take the soil and mound it upward as you dig to create a downslope. This slope will help with drainage and create a polished look.

Metal Edging

A metal or aluminum edge goes right inside your edging border. Metal borders come in a long, lightweight, and firm strip. Aluminum also provides a rust-free separation between flower beds and your lawn.

Plastic Edging

Plastic is the least expensive option for edging materials. It’s nearly indistinguishable between your grass and garden, as it comes in a long, stiff, clear strip. And, it’s easy to find and install from most home improvement retailers.

Brick Edging

Line the edge of your trench with stone dust, line up your bricks in and above the trench and mound them into place with a rubber mallet. Seal the bricks by adding water to the sand to create a heavy locking paste.

Concrete Edging

Fill your trench with a paver base and place your concrete pavers along the border. Add polymeric sand to the paver linings, hose them down with water, clear off the pavers, and set them into place.

Stone Edging

Stones are a natural material that creates a beautiful raised border along your flower beds. For this option, you’ll want to add a mound of fresh soil, stack your stones above your flower bed and secure them in place with an adhesive paste.

Now that you’ve created a beautiful edge around your flower bed, you’ll want to ensure that it continues to look immaculate. 

You can maintain your garden edge with the following tasks: 

• Trim your edges horizontally or vertically with garden shears or an electric yard trimmer after each mow.

• Carefully mow around your edges by following the straight or curved path.

• Clean up your flower beds after each mowing and when weeds start to grow.
