    • In fire-prone areas, create a “defensible space” around structures. Use non-combustible materials like gravel, concrete, or rock for at least 5 feet around any building.
    • Avoid deep layers of highly flammable materials (e.g., dry pine needles, fine bark mulch) close to your home or RV.
    • Choose living ground covers that are low-growing, succulent, and well-irrigated to reduce fire risk.
  • Pest Management:
    • Monitor new ground covers for signs of unwanted pests. Some organic materials can attract slugs, snails, or rodents.
    • Keep a tidy edge around structures to prevent pests from using ground covers as bridge access.
  • Allergies and Irritants:
    • Wear gloves, long sleeves, and a mask when handling dusty or irritating materials like some types of compost or wood byproducts.
    • Be aware of potential allergens if you’re working with certain plants as living ground covers.
  • Tool Use:
    • Always use appropriate tools (shovels, rakes, wheelbarrows) safely.
    • Wear sturdy work gloves to protect your hands.

By following these guidelines, you’ll not only create a beautiful and functional outdoor space but also ensure your safety and the longevity of your chosen ground covers.
