Outdoor flower pots and containers require proper winterization in order to survive the cold months. Even if no plants are in the pots, the pots themselves may suffer winter damage. Prepare the flower pots in late fall before the soil begins to freeze to ensure both the pots and the plants inside survive until next spring.
Dig up the roots or rhizomes of tender perennial container flowers such as begonia. Store the plants inside perforated plastic bags filled with dry peat moss in a 40-degree-F location until spring replanting.
Dump out the old potting soil from flower pots that had annuals and tender perennials in them. Place the soil into the compost pile.

Cover the soil in pots housing hardy perennials with a 2- to 3-inch layer of organic mulch. Use wood chips, bark or straw. Mulching preserves moisture in winter and helps prevent root freeze.
Move plants to a greenhouse, shed or garage to protect them from extreme winter cold and wind if possible. Alternately, move the flower pots to the side of a building or fence that is protected from heavy winds.
Turn empty pots upside down or place them in a covered area so they do not collect snow or water during winter. Standing water in pots may freeze, leading to cracked flower pots.

Place large, heavy planters on wheeled carts to make moving them easier in fall.
Take baskets down from where they are hanging when winterizing your flower pots. Winter winds may blow them down and damage them, or the weight of the frozen soil and heavy snow can potentially rip their hanging hooks out of the eaves.
Check soil in planters housing evergreen plants or dormant plants throughout winter for dryness. Water as needed, otherwise plants may suffer from dehydration or winter burning.
