A fire in the nursery building at Izzo's Country Gardens and Landscaping was quickly extinguished Thursday evening before causing significant damage.
The fire was reported to firefighters just before 6 p.m. Thursday, and fire crews arriving at the Post Road East plant nursery found that the flames were moving across the ceiling.
The fire was quickly doused by firefighters from Engine 5, the first crew on the scene.
The Post Road was briefly closed to traffic as a water-supply line was attached to the nearest fire hydrant.
Firefighters from Fairfield and Norwalk provided assistance both at the scene and as backup coverage for the rest of town.
The fire is being investigated by the Fire Marshal's office.
