Rock, crushed stone and other hardscape options can limit the amount of mulch used.One of your annual gardening tasks might involve applying a new layer of mulch to help control weed growth, reduce soil erosion and add nutrients to the soil.While your fruits, vegetables or ornamentals might benefit, mulch is a combustible material, and care must be taken to avoid the possibility of it igniting.

Once burning, mulch can be difficult to extinguish.TYPES OF MULCH Mulch is any material, organic or inorganic, used to cover the soil surface for a variety of purposes.Most organic mulches come from plant materials such as pine needles, wheat straw, pine bark nuggets, shredded cedar and redwood bark, or wood chips from recycled pallets.

Ground and shredded rubber are also considered organic mulches.Inorganic mulches, usually derived from non-plant materials, include rock, gravel or brick chips.THE FIRE DANGER Mulch can ignite in a variety of ways: Improperly discarded smoking materials Spontaneous combustion Sparks from wildland or other fires Factors that can increase the possibility of ignition include below-average rainfall, dry conditions, warm temperatures and high winds.

AVOIDING MULCH FIRES We can reduce the risk of mulch fires by: Watering to keep the garden consistently moist Installing inorganic mulch that is less likely to ignite Limiting mulch depth to no more than 3 inches Adding a non-combustible barrier, such as a rock bed, between the mulch and any structures on your property.If your mulch does ignite, this will allow more time to extinguish the fire, keeping you and your property safe Keeping fire pits or grills a safe distance from mulch beds Discarding cigarettes in proper receptacles, not in mulch or potted plants MORE INFORMATION The Combustibility of Landscape Mulches, University of Nevada Cooperative Extension Preventing Mulch Fires, Office of the State Fire Marshal, Massachusetts   This loss control information is advisory only.The author assumes no responsibility for management or control of loss control activities.
