Begonia tubers survive minimum temperatures of 40 degrees Fahrenheit and are winter-hardy in USDA plant hardiness zones 8, 9 and 10. They require winter storage at temperatures of 40 to 50 degrees Fahrenheit in climates with prolonged freezing spells. They are replanted outside once spring temperatures of 65 to 68 degrees Fahrenheit appear.
