Aloe Vera Plants need to be kept at temperatures between 55 and 80 degrees Fahrenheit, so you should only place them outdoors when temperatures are in this range. For most areas of the U.S., this means keeping them inside during the fall and winter months, and placing them outside in the spring and summer. If overnight temperatures drop below 55 degrees Fahrenheit, bring the Aloe Vera Plant inside to avoid frost, which can harm or kill the plant.
