Kentucky Frost Dates
Kentucky has a generally favorable growing season, with warm summers and enough variation in topography to keep frost timing interesting. River counties and the west usually warm sooner, while eastern hills and sheltered hollows can hold late spring frost and cool down faster in fall.
