In northwest Houston, the mulch fire at the Living Earth landscaping company is burning for a third straight day.
The flames were first reported Sunday afternoon at the Living Earth landscaping facility at 5802 Crawford Road in the Carverdale neighborhood.
Helicopter video spotted heavy machinery moving some of that smoldering material apart.
The Houston Fire Department said it was not putting any more water on the fire and is waiting for it to burn itself out. It could be days before it stops burning.
Mulch fires are stubborn due to how flammable it can become, especially in hot and dry conditions.
The exact cause of this fire is unknown, but fires like these are known to start by spontaneously combusting.
