Fuchsia plants do best in environments where the temperature remains between 55-85 degrees Fahrenheit, although some hardier cultivars have been developed. In most cases, below-freezing temperatures or consistently high temperatures will kill fuchsia plants. Keep an eye on the forecast and move your plant indoors if extreme weather is expected. These plants prefer humid conditions, so if you live in a dry climate, mist your fuchsia regularly to keep it healthy and blooming.
