The answer depends heavily on the type of wicker material. Natural wicker, made from materials like rattan, cane, or bamboo, is not designed for year-round outdoor exposure. Moisture, sun, and temperature fluctuations can cause it to crack, mold, and deteriorate quickly. It should be stored indoors or in a protected area during harsh weather, especially winter and rainy seasons.
In contrast, synthetic or all-weather wicker, typically made from resin or vinyl over an aluminum frame, is built to withstand the elements. It is UV-resistant, waterproof, and can generally be left outside throughout the year. However, even all-weather wicker benefits from protective measures to extend its lifespan. Using furniture covers during extreme weather, placing it in a partially shaded area, and performing regular cleaning are highly recommended best practices.
For long-term durability, always check the manufacturer's specific care instructions. Providing a covered space like a patio or using a high-quality, breathable cover is the best strategy to keep any wicker furniture—natural or synthetic—looking its best for seasons to come.
