Covering patio furniture during winter can protect it from snow, ice, moisture, debris, and Minnesota’s repeated freeze-thaw cycles. The right cover may extend the life of your outdoor furniture, preserve its appearance, and make spring cleanup easier.
However, furniture should always be clean and completely dry before it is covered. A poorly fitted or non-breathable cover can trap moisture and contribute to mold, mildew, rust, and material deterioration.
How Winter Can Damage Patio Furniture
Minnesota winters can be difficult on outdoor furniture.
- Moisture damage: Water can enter seams, joints, cracks, and porous materials. When it freezes and expands, it may cause cracking or deterioration.
- Rust and corrosion: Metal furniture and hardware can rust when moisture reaches exposed areas.
- Mold and mildew: Damp cushions and fabrics may develop mold or mildew when moisture becomes trapped.
- Fading and staining: Covers help protect furniture from sunlight, dirt, tree debris, and animal activity.
- Snow weight: Heavy snow and ice can strain furniture and damage poorly supported covers.
How to Winterize Patio Furniture
Before covering or storing your furniture:
- Clean it according to the manufacturer’s instructions.
- Allow every surface to dry completely.
- Repair loose hardware, cracks, or damaged finishes.
- Store cushions and fabric accessories indoors when possible.
- Move furniture to a garage, shed, covered porch, or sheltered area if space is available.
Choosing the Right Furniture Cover
Select an outdoor furniture cover that:
- Fits the furniture properly
- Resists water while allowing ventilation
- Includes vents to release trapped moisture
- Has straps, buckles, or ties for windy conditions
- Prevents water and snow from pooling
Avoid wrapping furniture tightly in an unvented plastic tarp. It may keep snow off while trapping condensation underneath.
Check Your Furniture During Winter
Periodically check for loose covers, trapped moisture, standing water, animal activity, and heavy snow accumulation.
When conditions are safe, remove excessive snow with a soft broom. Avoid sharp tools that could tear the cover or damage the furniture.
Does All Patio Furniture Need to Be Covered?
Not every material requires a cover. Some outdoor furniture is designed to remain outside throughout the year. Always follow the manufacturer’s care instructions.
Even weather-resistant furniture may benefit from cleaning, protection, and sheltered storage. When indoor storage is available, it generally provides the best protection during a Minnesota winter.
A little fall preparation can help prevent moisture damage, rust, mold, fading, and freeze-thaw deterioration while making it easier to enjoy your outdoor space again in the spring.
