PHOENIX — Authorities say a mulch fire at a north Phoenix plant nursery is smoldering after burning about eight acres.
Phoenix Fire Department officials say the blaze broke out Wednesday afternoon at the Bella Gardens Nursery.
Flames were fed by the nursery's green dumping grounds, which provided trees, plants and mulch.
About 80 firefighters went to the scene, which is isolated from water sources.
Crews used trucked-in water to prevent the fire from moving closer to Interstate 17.
Fire officials say the blaze started on its own. Mulch produces heat as the organic materials that make it decompose.
The owners of Bella Gardens Nursery are using water tankers to manage the smoldering mulch piles.
Fire officials may be overseeing it for a couple of days and the air quality is being monitored.
