Whether you can leave your outdoor furniture outside all year depends on several factors, including the material it's made from, your local climate, and whether you take protective measures. Generally, it's possible, but doing so without proper care can lead to damage, shortening the furniture's lifespan.
The biggest threats to outdoor furniture are sun, rain, snow, and extreme temperature changes. Ultraviolet (UV) rays from the sun can cause fading and weaken materials like wood and plastic. Moisture from rain and snow can lead to rust on metal frames, mildew on cushions, and rot in wood. Freezing temperatures can make some materials brittle and cause cracking.
Here’s a quick guide by material:
* Wood (Teak, Cedar): Durable hardwoods like teak can withstand the elements well and develop a silvery-gray patina. Softwoods require regular sealing. All wood benefits from being covered or stored in harsh winters.
* Metal (Wrought Iron, Aluminum): Aluminum is lightweight and rust-resistant, making it a good year-round choice. Wrought iron is sturdy but must have a protective powder coat to prevent rust; check for scratches.
* Plastic/Resin: Highly weather-resistant and a good option for leaving out. However, it can become brittle in cold weather and may fade in intense sun.
* Wicker (Synthetic): Synthetic wicker is designed for outdoor use and holds up well, but it should be covered to prevent dust and moisture buildup in its weave.
To protect your furniture if you decide to leave it outside, follow these tips:
1. Use High-Quality Covers: Invest in waterproof, breathable covers tailored to your furniture. This is the single most effective step.
2. Store Cushions and Pillows: Always bring cushions, pillows, and fabrics indoors or into a dry storage box. They are highly susceptible to moisture and mold.
3. Clean Regularly: Clean your furniture at the start and end of the season to remove dirt, pollen, and debris that can cause stains or deterioration.
4. Elevate if Possible: Raising furniture slightly off the ground, especially on a deck or patio, helps prevent moisture from being trapped underneath.
In conclusion, while you can leave many types of outdoor furniture outside all year, it requires mindful material selection and a commitment to maintenance. For harsh winter climates, storing furniture in a garage or shed is the safest option to ensure it looks great for many seasons to come.
