The habitat which the Smooth Green snake is found in includes grassy, moist meadows, native prairies, and clearings in pine forests.

Smooth Green snakes are day snakes, often found moving through grasses or shrubs. Their primary foods are worms, grubs, crickets, grasshoppers and smooth caterpillars. Some of this species decline may be due in part to pesticide use on their food sources.

Smooth Green snake reproduction occurs in the spring but the egg laying varies by individual. Egg clutch sizes range from 3-15 eggs. Some females will incubate the eggs until just a few days before they hatch, others will be laid and hatch around one month later.

Hibernation can include many individuals and their may be several snake species such as Garter or Red-bellied snakes with the hibernating Smooth Green snakes.
