Provide shelter for your plants by moving them indoors or under an overhang that's sheltered from the elements. Remove any stems that have died or dried leaves that are falling off plant stems. Cut back to healthy foliage and give it very little water, if any. If you live in a climate where you can leave your plants outside during winter, move them to an area that receives partial sunlight and shelter them from the wind. Continue to protect until nighttime temperatures are above 50 degrees Fahrenheit (10 Celsius).
