The answer to whether you can leave wicker furniture outside all winter depends entirely on the material it is made from. The critical distinction is between natural wicker and synthetic (all-weather) wicker.
Natural wicker, crafted from materials like rattan, cane, or bamboo, should never be left outdoors in winter. It is highly susceptible to moisture, which can lead to mold, mildew, and rot. Freezing temperatures make the fibers brittle, causing them to crack and break. For natural wicker, proper indoor storage is mandatory.
Synthetic or all-weather wicker, typically made from resin or vinyl, is designed to withstand the elements. It is generally safe to leave outside during colder months. However, to maximize its lifespan and appearance, taking protective measures is highly recommended. Prolonged exposure to snow, ice, and moisture can still cause fading or a buildup of grime.
For optimal protection of all-weather wicker, follow these steps:
1. Use high-quality, breathable, waterproof furniture covers to shield it from direct snow, ice, and rain.
2. If possible, move the furniture to a more sheltered location, such as under a covered patio or against the house, to minimize direct exposure.
3. Before covering, ensure the furniture is clean and completely dry to prevent trapping moisture.
4. Adding cushions to indoor storage will prevent them from absorbing water and developing mold.
In summary, store natural wicker furniture indoors for the winter. You can leave all-weather wicker outside, but protecting it with covers and strategic placement will ensure it looks great for many seasons to come.
