Can a mandevilla plant surrive in the ground in the winter months in KY?

Mandevilla plants are typically not hardy enough to survive in the ground during winter months in Kentucky, as they are sensitive to frost and cold temperatures. They are generally considered tropical or subtropical plants and thrive in warmer climates. To protect them, it's best to bring them indoors or provide adequate winter protection, such as mulching or covering, if you want to attempt keeping them in the ground. However, for best results, many gardeners choose to treat mandevilla as an annual in colder regions.
