How to get rid of weeds growing in driveway cracks

Posted on

Introduction

Are weeds popping up between the cracks in your driveway, making it look messy and neglected? You’re not alone. Driveway cracks are the perfect breeding ground for weeds, thanks to trapped soil, moisture, and sunlight. Learning how to get rid of weeds growing in driveway cracks not only improves curb appeal but also prevents long-term driveway damage. In this guide, you’ll discover proven methods to eliminate weeds, stop them from returning, and restore your driveway’s clean, polished look.

Why Removing Weeds Matters for Your Driveway

Weeds might look harmless, but they can cause significant problems if left unchecked:

  • Driveway damage – Roots push deeper into cracks, widening them and leading to costly repairs.
  • Reduced safety – Weeds create tripping hazards and make surfaces uneven.
  • Lower curb appeal – Nothing spoils the look of a driveway faster than weeds sprouting through cracks.
  • Encourages further growth – Once weeds take hold, they spread quickly across the entire driveway.

By removing weeds promptly, you protect your driveway’s structure, maintain safety, and keep your home exterior looking its best.

Step-by-Step Guide to Removing Weeds

1. Gather the Right Tools and Supplies

You’ll need:

  • Garden gloves and safety goggles
  • A screwdriver, putty knife, or weed removal tool
  • A stiff-bristle brush
  • Weed killer (natural or chemical)
  • Garden hose or pressure washer
  • Sealant for driveway cracks

2. Pull Out Visible Weeds by Hand

Start by removing as many weeds as possible manually. Grip them firmly at the base and pull straight up to get the roots. Use a screwdriver or weeding tool to pry out stubborn weeds lodged deep in the cracks. This prevents them from regrowing.

3. Apply a Weed Killer Solution

Once you’ve cleared the surface, apply a weed control treatment:

  • Natural Solutions
    • Boiling water: Pour directly into cracks to kill weeds instantly.
    • Vinegar: Use household vinegar or horticultural vinegar for tougher weeds. Apply on sunny days for best results.
    • Salt: Sprinkle sparingly to dehydrate weeds, but avoid overuse as it can harm nearby soil.
  • Chemical Solutions
    • Apply a driveway-safe herbicide following the manufacturer’s instructions. Choose a product labeled for cracks and crevices to ensure effectiveness.

Allow the solution to penetrate for several hours or as directed.

4. Scrub and Clean the Cracks

Use a stiff-bristle brush to scrub dead weeds and roots out of the cracks. For larger areas, a pressure washer can blast away debris and remaining organic matter. This ensures a clean surface before sealing.

5. Fill and Seal Cracks

After removing weeds and cleaning the cracks, let the driveway dry completely. Use asphalt crack filler or concrete patch, depending on your driveway type, to fill the gaps. Once cured, apply a sealant across the surface. Sealing prevents water penetration, discourages weed regrowth, and extends driveway life.

6. Repeat as Needed for Maintenance

Weeds are persistent, so inspect your driveway monthly. Spot-treat small growths immediately before they spread. Regular upkeep keeps your driveway clean and weed-free.

Common Mistakes to Avoid

  1. Only Cutting Weeds at the Surface
    Mistake: Snipping weeds without removing roots.
    Solution: Always pull weeds out completely, including roots, to prevent regrowth.
  2. Overusing Salt or Vinegar
    Mistake: Applying too much, which can damage surrounding soil and nearby plants.
    Solution: Use natural treatments sparingly and only in cracks.
  3. Skipping Crack Sealing
    Mistake: Leaving cracks open after weed removal.
    Solution: Fill and seal cracks to block future growth.
  4. Not Following Herbicide Instructions
    Mistake: Over-applying chemicals and damaging surfaces.
    Solution: Always follow the label directions carefully.
  5. Ignoring Regular Inspections
    Mistake: Waiting until weeds are out of control.
    Solution: Perform monthly inspections and address small weeds early.

Extra Driveway Tips & Hacks

  • Flame Weeding: For stubborn growth, use a propane weed torch to burn weeds at the root. Always follow safety guidelines.
  • Install Edging: Adding edging along the driveway helps prevent seeds and soil from blowing into cracks.
  • Combine with Pressure Washing: After removing weeds, pressure wash the surface to eliminate spores and debris that encourage regrowth.
