Idaho Firewise is dedicated to educating homeowners about fire protection for their homes. One of the most frightening experiences is seeing your home surrounded by wildfire and being powerless to do anything to stop it. Idaho Firewise wants to show homeowners the principles of designing defensible space with fire-resistant landscapes and fire-resistant plant materials.
Zone 1- Your buildings and the first 30 feet. The plant materials here should be green and clean. Use low-growing, fire-resistant plants, and turf and remove leaf litter, etc. Use gravel mulches rather than wood materials.
Zone 2- From 30 to 100 feet. The plant materials in this space should be pruned and groomed, with firewood and propane tanks on non-flammable pads. Tree canopies separated by at least 18 feet. Trees should be pruned up to 6-10 feet with cleared spaces underneath, no other plantings under the trees.
Zone 3-100 feet and beyond to the native vegetation. Remove any dead plants, thin and prune as needed, provide irrigation.
Gardentronic has added images and information on many of the Firewise plants. If you want to view plants that are on the Firewise list, search here Plants Then in the search bar, type the words "firewise" you will then see a display of plants in our database that are from the Firewise website.
Each plant will have information on Firewise's recommended planting zone. How far away should this plant be from my buildings to maintain a defensible space? Should I plant 30 feet away to protect my home, or do I need to put them 100 feet away? Here are a few examples:

Many of the evergreens that grow well in Idaho have been given a Firewise rating of 1, meaning it is recommended they be planted 100 feet or more from your home to maintain the best defensible space.
The best way to understand a concept is to see it in real life. Firewise has several demonstration gardens in Idaho to show landscaping principles in action.
There are currently eleven
