Long-Term Weed Control for Gravel Driveways Using Soil Sterilants

Introduction

Gravel driveways need a weed barrier that lasts months. Salt-based soil sterilants provide 6–12 months of control.

Product Selection

• Choose herbicides labeled for "patios" or "driveways."
• These contain sodium salts that persist in soil, preventing all plant growth.
• Avoid products that only kill active growth and dissipate quickly.

Application

Follow label rates. Apply to dry gravel; water in if required. Reapply when weeds reappear (typically 6–12 months).

Note on Borates

Fire-retardant borates used in forest fires are not standard driveway products. Stick to commercial driveway herbicides.

Conclusion

Salt-based sterilants are the practical choice for long-term, low-maintenance weed suppression in gravel driveways.
