Remember that fire does not respect property lines, so the whole community needs to be involved. One person's best effort at fire safe landscaping may be at the mercy of a neighbour's complacency. Any plant can burst into flame during severe fire danger weather. Most plants accumulate excess woody material and all shed some seasonal foliage. Branches spread, often touching other vegetation.
Weeds grow between landscape plants.
You must actively reduce the accumulation of potential fuel by regular pruning, mowing and raking, followed by proper disposal. The less accumulated plant debris, the slower a fire will spread. Reducing the amount of fuel limits the fire's intensity. Low volume of total vegetation High moisture content in leaves Drought tolerance Slow growth, requiring less frequent pruning Remove combustible materials from around all structures, and propane or other fuel tanks. This includes ground and ladder fuels, woodpiles, building materials, cardboard boxes, and solvents.
