Overview
Define clean edges between lawn and beds. Add fresh mulch 2-3 inches deep to suppress weeds, retain moisture, and give your landscape a polished look.
Step-by-Step Guide
Plan your edge lines
Use a garden hose or spray paint to outline the desired edge shape along beds and walkways. Step back and evaluate the line from multiple angles before cutting.
Cut the edge with a half-moon edger or flat spade
Drive the blade straight down 3-4 inches along your guideline. Angle the cut slightly toward the bed so the turf side is vertical and the bed side slopes away.
Remove the turf strip
Peel back the sod and grass from the bed side of the cut. Shake off loose soil and compost the turf or use it to patch bare spots in the lawn.
Create a shallow trench
Scoop out a V-shaped or flat-bottom trench 2-3 inches deep along the edge. This trench prevents grass stolons from creeping back into the bed.
Remove old mulch and debris from beds
Rake out decomposed mulch, fallen leaves, and weed material from the bed. Pull any weeds that have established roots near the edge.
Spread fresh mulch evenly
Apply 2-3 inches of hardwood, cedar, or pine bark mulch across the entire bed. Keep mulch 2-3 inches away from plant stems and tree trunks to prevent rot.
Clean the walkway edges
Sweep or blow stray mulch and soil off walkways, driveways, and patios. A leaf blower makes quick work of this step.
What You'll Need
Tools
- - Half-moon edger or flat spade
- - Garden hose or marking spray paint
- - Steel rake
- - Wheelbarrow
- - Work gloves
- - Leaf blower or broom
Materials
- - Mulch (hardwood, cedar, or pine bark) — 2-3 cubic yards per 100 sq ft of bed area
- - Landscape fabric (optional, for new beds)
Cost Estimates
DIY Cost
$30–$80 (mulch and edging tool)
Professional Cost
$150–$400 depending on linear footage and mulch volume
Safety Tips
- Wear steel-toed boots when driving edging tools into the ground.
- Call 811 before edging near utilities to locate underground lines.
- Lift mulch bags with your legs, not your back — they can weigh 40+ lbs when wet.
When to Call a Professional
Call a landscaper if you have more than 200 linear feet of edging, need to install permanent steel or aluminum edging, or want to reshape beds with retaining walls.
Pro Tip
Edge beds in early spring before mulching and again in late summer for a crisp look year-round. A sharp edge is the single biggest visual upgrade you can give your landscaping.
Common Mistakes to Avoid
- Piling mulch against tree trunks (volcano mulching) — this causes bark rot and invites pests.
- Cutting edges too shallow — the grass creeps back within weeks without a proper 3-4 inch cut.
- Applying mulch more than 4 inches deep — this suffocates plant roots and repels water.
- Skipping old mulch removal — layering new mulch on top of decomposed mulch raises the bed level too high over time.
