Creating a Fire-Resistant Landscape With Proper Tree Care

The Clarks used local resources to design a landscape that would help them reach their goal of defensible space. They have gravel and rock surfaces within 30 feet of the house, plus a mixture of grasses and low-growing fire-resistant plants.

They also have good vertical spacing of shrubs and trees to prevent crown fires, which can move quickly through tree canopies. They also keep a 10-foot ember-resistant zone around woodpiles and propane tanks.

1. Plant Fire-Resistant Trees

A fire-safe landscape starts with thoughtful plant selection. Most people typically choose plants based on factors like flower color, light requirements, habitat value, or aesthetics. However, it is crucial to prioritize plants that are well-adapted to the site. Equally important is the practice of grouping plants with similar soil, water, and sunlight needs together.

The initial “zone,” spanning 30 feet from the house, should feature fire-resistant shrubs and ground covers such as ice plant, sedum, purple coneflower, or wild lilac. It is advisable to steer clear of ornamental grasses and conifers in this zone, as they tend to be more flammable. Instead, consider incorporating shrubs with low-growing ground cover characteristics like red penstemon or sulfur buckwheat, which are native to Idaho and not only offer aesthetic appeal but also attract wildlife.

In addition to incorporating fire-resistant plants, strategic hardscaping plays a crucial role. Elements such as rock gardens, gravel pathways, or the use of a dry riverbed or water feature can effectively disrupt the continuity of vegetation and fuels. This, in turn, helps slow down the spread of fire, contributing to a safer environment. Considering the importance of fire safety, it’s wise for residents in regions like Boise to integrate these landscaping practices, prioritizing local conditions and the surrounding environment without necessitating drastic measures like Boise tree removal.

2. Keep Your Trees Healthy

A healthy tree is less prone to fire damage and is more likely to survive a wildfire. Proper planting, watering and care can help keep trees healthy and reduce their risk for fire.

Firescaping emphasizes the use of plant species that are low-flammability, drought tolerant and native to your area. These plants can add color and texture to your landscape while providing a fire-resistant buffer around your home.

Plants with a high moisture content and open branching habits are more fire-resistant. Deciduous trees are typically more fire-resistant than conifers such as pines, spruces and junipers (which have thick needles instead of leaves).

The first step in a firescaping plan is creating defensible space around your house. Defensible space includes the zone up to 200ft from your home that is free of combustible materials and provides firefighters a safe work area to defend your home. Horizontal and vertical spacing between plants is also important to prevent flames from spreading.

3. Trim Trees Regularly

When it comes to fire resistance landscaping, pruning is a critical part of the process. It removes dead or diseased limbs and thins the canopy to reduce overall flammability. Additionally, it ensures that trees can withstand destructive winds and prevents limbs from falling during a fire.

It’s important to prune on a regular schedule, so that a tree is not overgrown. If a tree is allowed to grow too large, it will be difficult for the crown to seal wounds and resist insect infestation. Moreover, large cuts can compromise the structural integrity of a tree and make it vulnerable to wind or fire.

Zone 1, the area closest to your home, should be kept “lean and green” by regularly irrigating low-flammability plants and removing dead vegetation. In addition, you should keep a 10-foot fire break around your home, sheds, decks, and propane tanks. Also, keep the grass mowed and weeds cleared at all times. Mulching the soil around trees reduces weed growth, holds moisture, and keeps lawnmowers and weed eaters away from the trunks.

4. Don’t Forget About Fall Cleaning

In the wild, fire serves an important role by removing dead and decadent plant material to make way for new seedlings and recycles and makes available essential plant nutrients. This natural process can also be employed to reduce a landscape’s fuel load and prevent fire from spreading.

For example, homeowners in Boise who have designed a defensible space should avoid planting grass and other flammable plants within 30 feet of their home and instead choose ground covers such as low-growing native Idaho plants like firecracker red penstemon or sulfur buckwheat that are slow to burn. A landscape plan may also include Zone 3, which extends out 100 feet from the home and focuses on keeping large shrubs, conifers, and other flammable plants away from the house.

Additionally, maintaining a fire-resistant landscape often involves clearing out dead vegetation and pruning weeds and other flammable plants from lawns and landscape beds. This can be done in the fall to ensure that plant materials don’t accumulate throughout the winter and prevent the spread of fire in the landscape.
