Why Do Weeds Grow in Driveways?
Driveways may seem like tough surfaces, but cracks, gaps, and loose materials provide the perfect environment for weeds and grass to take hold.
🔹 Soil and debris build up in cracks, creating a space for weed seeds to germinate.
🔹 Moisture collects in gaps, helping weeds survive even in hot, dry weather.
🔹 Seeds from nearby lawns and plants get blown into the cracks by wind or traffic.
Once weeds establish themselves, they can expand cracks, damage asphalt or concrete, and make your driveway look unkempt.
The good news? Stopping weeds before they grow is much easier than removing them later!
Best Ways to Prevent Grass and Weeds in Your Driveway
1. Fill and Seal Cracks
🚧 Prevention Level: High
🔹 Small cracks eventually turn into big ones—sealing them early prevents weeds and structural damage.
✅ How to Do It:
- Clean cracks thoroughly using a pressure washer or stiff brush.
- Apply a concrete, asphalt, or paver sealant to prevent weeds from sprouting.
- For larger gaps, use flexible joint fillers or polymeric sand.
✔ Best for: Concrete, asphalt, and paver driveways.
2. Use Chemical Weed Killers
💀 Prevention Level: High
🔹 Chemical herbicides kill weeds at the root and stop new ones from growing.
✅ Best Options:
- Pre-emergent herbicides (stops seeds from sprouting).
- Post-emergent weed killers (kills existing weeds).
- Total vegetation killers (wipes out everything for months).
⚠️ Things to Keep in Mind:
- Avoid spraying near lawns or gardens, as chemicals can drift.
- Some herbicides last up to a year, so choose carefully if you want future plant growth nearby.
✔ Best for: Driveways with recurring weed problems.
3. Use Natural Weed Killers
🌱 Prevention Level: Medium
🔹 If you prefer a chemical-free approach, there are natural alternatives:
✅ Best Natural Options:
- Boiling Water – Instantly kills weeds by destroying their cells.
- Vinegar & Salt Solution – Dries out and kills weeds (mix 1 gallon vinegar + 1 cup salt + 1 tbsp dish soap). Use a more concentrated vinegar for quicker results.
- Baking Soda – Sprinkling it in cracks makes the soil less hospitable for weeds.
⚠️ Things to Keep in Mind:
- Vinegar and salt can affect nearby plants and soil quality.
- Natural options may require multiple applications for stubborn weeds.
✔ Best for: Homeowners who want an eco-friendly weed control solution.
4. Install Polymeric Sand in Paver Joints
🧱 Prevention Level: High
🔹 Paver driveways are notorious for weeds growing between joints, but polymeric sand can fix that.
✅ How It Works:
- When applied between pavers and hardened with water, polymeric sand forms a solid barrier that prevents weed growth.
- Stops ants and erosion while keeping your driveway intact.
✔ Best for: Brick or stone paver driveways.
5. Use Landscape Fabric Under Gravel Driveways
📉 Prevention Level: High
🔹 If you have a gravel driveway, installing weed barrier fabric underneath can prevent weeds from ever breaking through.
✅ How to Do It:
- Remove the top layer of gravel and clear out any weeds.
- Lay high-quality landscape fabric over the base layer.
- Reapply gravel over the fabric, compacting it for stability.
✔ Best for: Gravel driveways with recurring weed issues.
6. Regularly Sweep & Edge Your Driveway
🧹 Prevention Level: Medium
🔹 A clean driveway discourages weed seeds from settling in cracks.
✅ Maintenance Tips:
- Sweep weekly to remove debris and soil buildup.
- Use a string trimmer along driveway edges to prevent encroaching grass.
- Blow away loose dirt after mowing to stop grass clippings from taking root.
✔ Best for: All driveway types—prevention is always easier than removal!
When to Hire a Professional for Driveway Weed Prevention
While DIY methods work well, persistent weed problems may require professional treatment. A lawn and landscape professional can:
✔ Seal cracks and joints with long-lasting materials.
✔ Apply high-grade herbicides for season-long prevention.
✔ Properly install polymeric sand or landscape fabric for long-term weed control.
