🌿 Bark Mulch Fire Safety

Bark mulch is a popular landscaping material—but under the right conditions, it can become a serious fire hazard.

🔥 Why Mulch Fires Happen

  • Hot, dry weather and low rainfall increase the risk.
  • Fires often start from discarded smoking materials like cigarettes or matches.
  • Mulch can smolder unnoticed, especially when placed against buildings.
  • Once ignited, fire can spread quickly to shrubs, decks, siding, and even the structure itself.

🚫 Common Risk Factors

  • Mulch beds placed too close to buildings
  • Improper disposal of smoking materials
  • Dry, windy conditions that accelerate fire spread

✅ How to Reduce the Risk

  • Keep mulch moist, especially during dry months.
  • Maintain at least 18 inches of clearance between mulch and any combustible building materials.
  • Never discard cigarettes or matches into landscaped areas.
  • Consider using non-combustible ground cover (like gravel) near building foundations.


Mulch fires can cause extensive damage before they’re even noticed. By taking a few simple precautions, you can help protect your home or business from this hidden hazard.
