What's the best way to clean up the edges of my driveway where the grass keeps creeping in?

Driveway edge creep is a constant battle in Ottawa, especially in established neighbourhoods like Nepean, Alta Vista, and Old Ottawa South where mature lawns aggressively encroach on driveway borders.

Why Edges Deteriorate

Ottawa's cycle of frost heave and spring thaw pushes soil and grass toward your driveway. Snow ploughs pile snow on edges all winter, compressing the lawn into the driveway border. By spring, the clean edge you had in September has disappeared under 5 cm of turf.

Manual Edge Cleanup (Best DIY Method)

A half-moon edging tool ($20 to $35) is the most effective tool for this job. Here's the process:

Mark your line — Stretch a string line or garden hose along the original driveway edge. On asphalt, the edge is usually visible as a slightly raised lip underneath the encroaching grass.

Cut along the edge — Drive the half-moon edger straight down along the driveway edge, cutting through grass and roots. Apply firm foot pressure.

Remove the strip — Pull out the cut grass strip and shake off loose soil. Compost the green waste.

Clean the gap — Use a flat shovel or trowel to remove compacted soil from the driveway edge, exposing the full width of the asphalt or concrete.

Optional: install edging — For a lasting solution, install plastic or aluminum driveway edging ($1.50 to $3.00 per linear metre) to create a physical barrier.

Power Edging Option

A string trimmer turned on its side does quick edge work. Hold it vertically and walk along the driveway edge. This takes 15 to 20 minutes for a typical two-car driveway. For a cleaner cut, dedicated power edgers are available to rent for $35 to $50 per day in Ottawa.

Preventing Regrowth

• Edging material — Pound in aluminum or steel landscape edging flush with the driveway surface. This stops root creep underground. Budget $40 to $80 for a full driveway perimeter.
• Gravel border — Some homeowners in Kanata and Orleans create a 10 to 15 cm gravel strip between lawn and driveway. This creates a mow strip and suppresses grass encroachment.
• Edge twice per year — A quick pass in late May and again in September keeps edges sharp year-round. Each session takes about 20 minutes once you've done the initial cleanup.

Dealing with Heaved Edges

If frost heave has pushed your driveway edges up or the asphalt is crumbling at the edges, edging alone won't fix it. Edge crumbling is common on driveways in Ottawa that are 15+ years old. The asphalt edge needs professional repair — either patching with hot mix or installing a concrete curb.

Cost Summary

• Half-moon edger: $20 to $35 (one-time purchase)
• Aluminum edging: $40 to $80 for full perimeter
• Power edger rental: $35 to $50 per day
• Professional edge repair: $200 to $600 depending on severity

If your driveway edges are crumbling or the asphalt has broken away, that's beyond a DIY edging job. Browse Ottawa Driveways to find contractors who specialize in driveway edge repair and restoration in your part of the city.
