A fire sparked up in a corn field behind Pickett Elementary around 3 this afternoon.
Multiple fire engines from St. Joseph were called to the scene after it spread to trees around the area.
The Dekalb and Agency Fire Departments also responded.
Captain Tom Roe says people need to be careful this time of year because there is a higher risk for fires.
"First of all, barbeques, be careful with them, watch out," Roe said. "(There's) no open burning this time of year because of the winds that we've had. Just be careful with anything involving fire."
The fire department does not know how the fire started.
Crews looked for hot spots in the area and watered them down so it would not spread.
The National Weather Service issued a red flag warning today, meaning there was a higher risk for fires.
Roe says he expects his crew to respond to more grass fires now that open burning season is approaching.
