Plumeria is sensitive to frost and freezing temperatures, which can damage the plant’s cells and lead to wilting or dieback. To protect your Plumeria from frost damage, move potted plants indoors or to a sheltered area before the first frost. In colder climates, cover in-ground Plumeria with frost cloth or burlap to insulate against frost. Avoid watering the plant before a frost, as wet soil can freeze more easily. Providing winter protection will help ensure your Plumeria survives cold weather and regrows when temperatures rise.
