The US Department of Agriculture created a guide for different types of succulents, providing information for minimal winter temperatures in which these plants may or may not continue to thrive. This guide is called the hardiness zone, determining the ability of succulents to thrive and grow in 13 different temperature zones based on the hardiness level.

According to the guide, level 1 represents the coldest zone and level 13 stands for the warmest temperature zone. The temperature difference between each zone is set at 10 degrees Fahrenheit. Based on the type of succulents you are growing in your garden or planted in pots and kept indoors, you can determine the lowest and highest winter temperature for succulents so that your plant would continue to thrive during the change of seasons.

Other countries have also adopted the hardiness zone guide, so you may successfully determine the optimal temperature for succulents you are growing by finding out the hardiness zone of the plant.
