A. Not all the plants growing on your property present a threat and some can be helpful. Trees help keep the surface cool when their canopy is green. Some green ‘Fire-wise’ plants in the understory can slow the spread of flames with their moisture, if they are well maintained and watered. Some native, or low-growing evergreen broadleaf plants can keep the area cool and resist flames if they are watered or retain moisture. Trees native to our area, such as Oaks and Ponderosa pines, and introduced Redwoods are not highly flammable and can help keep the area around your home cooler. These trees should be limbed up but can be an important part of the landscape. A Defensible Space Advisor can help you with determining which plants add value and which need mitigation.
