Plants in hanging baskets suffer damage from freezing temperatures in much the same way that plants in other containers and plants in the soil do. Gardeners can minimize this damage by moving the hanging baskets to sheltered areas when freezing temperatures are expected. Gardeners who live in regions that allow outdoor planting year-round often plant winterized hanging baskets filled with plants that are able to withstand colder winter temperatures.
Cut the fleece so that you can line the inside of the hanging basket with a double layer. Fold several sheets of newspaper to use as an inner liner. Dampen the newspapers with water.
Place the saucer into the bottom of the hanging basket. The saucer will help to reserve water in the basket and will insulate the bottom of the basket from cold. Place the double layer of fleece around the inside of the hanging basket. Place the dampened newspapers against the layers of fleece.
Fill the basket with a mixture of potting soil and the granular fertilizer. Consult the fertilizer package for measurement recommendations for the size of your basket.
Plant the winter flowers in the hanging basket, planting them at the same depth as they were in the temporary containers.
Water the winterized hanging baskets every third day during the winter.
Move the hanging baskets to a sheltered area if you expect extremely cold temperatures. A porch, garage or basement would be suitable shelter during freezing temperatures. Return the baskets to their regular locations after the weather warms again.
