When does ragweed season end in Georgia?
Ragweed season in Georgia typically ends with the first frost, around November 10. The coldest corners of the state see frost by early November; the mildest hold out until early December.
Ragweed keeps releasing pollen until a freeze kills the plants, which is why the season has no fixed end date — it ends when the cold arrives. More on how frost ends ragweed season.
