Fire-Safe Landscaping in Southern Arizona: Protect Your Home from Wildfire

It started with a spark.

One hot June afternoon in the foothills near Tucson, Maria was hosting a backyard barbecue for her family. As the carne asada sizzled on the grill, a gust of wind carried an ember into a patch of dry grass along her fence line. Within minutes, flames spread to nearby shrubs and a mesquite tree just steps from her home.

Thankfully, Maria had prepared. Months earlier, she’d worked with a professional landscaping company to create a defensible space—removing flammable debris, spacing plants wisely, and replacing wood mulch with gravel. Because of those smart decisions, firefighters were able to contain the blaze before it reached her home.

Maria’s story isn’t rare. In Southern Arizona, wildfire risk is increasing due to longer dry seasons, high temperatures, and invasive grasses like buffelgrass. Whether you live near open desert or in a suburban neighborhood, fire-safe landscaping can mean the difference between a close call and catastrophe.

What Is Fire-Safe Landscaping?

Fire-safe landscaping is the practice of designing and maintaining your yard to reduce the spread of wildfire. It focuses on slowing fire and giving emergency crews time and space to act. In Tucson and surrounding areas, the right approach can protect not just your property, but your entire neighborhood.

Key Principles for Southern Arizona Fire Safety

1. Create Defensible Zones

The Arizona Department of Forestry and Fire Management recommends three defensible space zones:

• Zone 1 (0–5 feet): Use gravel or decomposed granite. Avoid flammable plants and keep this zone clear of debris.

• Zone 2 (5–30 feet): Use fire-resistant plants like agave and red yucca. Space trees and shrubs to avoid overlapping canopies.

• Zone 3 (30–100 feet): Thin native vegetation, remove invasive species, and keep grasses trimmed to reduce fuel.

2. Use Fire-Resistant Plants

Many desert-adapted plants are naturally firewise. Consider:

• Red yucca (Hesperaloe parviflora)

• Desert spoon (Dasylirion wheeleri)

• Ocotillo (Fouquieria splendens)

• Desert marigold (Baileya multiradiata)

Avoid high-oil or fast-spreading plants like eucalyptus, fountain grass, or oleander.

3. Maintain Regularly

Even the best landscape needs care. Prune dead branches, clear leaf litter, and check your irrigation system. Healthy, hydrated plants are less likely to burn.

Southern Arizona’s Unique Threat: Buffelgrass

Invasive species like buffelgrass dramatically increase fire risk. This fast-growing grass fills gaps between native plants, creating a continuous fuel bed. Removing it is one of the most effective things you can do to protect your home. Learn more at the Southern Arizona Buffelgrass Coordination Center (SABCC).
