Whether your garden bench can brave the winter outdoors depends largely on its material. The short answer is: some can, but most benefit from protection or storage.
For durable materials like powder-coated steel, cast aluminum, or high-quality synthetic rattan, leaving them outside is often acceptable if properly prepared. Ensure they are clean, dry, and consider using a fitted waterproof cover that allows for air circulation to prevent moisture buildup and mold.
However, natural materials like untreated wood, wrought iron (which can rust), and cheap plastics are winter-vulnerable. Untreated wood will crack and warp from freeze-thaw cycles and moisture. For these, indoor storage in a garage or shed is the best choice. If storage isn't possible, a full, breathable cover and elevation off wet ground are crucial.
Here’s your essential winter prep checklist:
1. Clean Thoroughly: Remove all dirt, sap, and debris.
2. Apply Protector: Treat wood with a fresh sealant and metal with a protective wax or coating.
3. Elevate & Cover: Place benches on feet and use a breathable, waterproof cover.
4. Secure or Store: Anchor lightweight benches against wind or move vulnerable ones indoors.
A well-maintained bench, whether left outside under cover or stored, will reward you with many more seasons of peaceful rest in your garden. When in doubt, protecting your investment by storing it is always the safest bet.
