Is wood chip mulch a fire hazard?
Coarse textured organic mulches, like wood chips, are the least flammable of the organic mulches. Fine textured mulches are more likely to combust, and rubber mulch is the most hazardous of all tested landscape mulches. If organic mulches are kept moist, they are less likely to catch fire. If you use flamers for weed control in areas near wood chips, be sure to soak the mulched area first.
