Can Rattan Furniture Be Left Outside in Winter?

Can rattan furniture brave the British winter? Short answer: Yes, but it needs a little TLC. While luxury garden furniture like PE rattan can handle the chill, snow and soggy cushions aren’t exactly stylish. Want it to survive (and thrive) till spring? Read on for must-know tips and winter-saving hacks!

The Winter Threat: How Cold and Wet Weather Affects Rattan

Impact on Natural Rattan

Moisture absorption leading to swelling, cracking, and rot

Natural rattan is beautiful, but it’s not made for soggy British gardens. When left out in the rain, it acts like a sponge—soaking up water and warping as it dries unevenly. Over time, this leads to cracking, swelling, and eventual rot. If your rattan’s looking a little warped after a wet week, you’re not imagining it.

Freezing temperatures causing brittleness and breakage

Come January, when frost coats the garden, natural rattan becomes fragile. The cold makes the fibres brittle, so the next time someone plonks themselves down, you might hear a snap instead of a creak.

Mould and mildew growth in damp, unventilated conditions

Let’s face it—mould loves moisture. Leave rattan in a damp corner or cover it poorly, and you’ll return to a musty, speckled mess. Mildew loves to hide in the nooks and crannies of the weave.

UV degradation even in winter sunlight

Even in winter, the sun has a sneaky way of fading and weakening natural fibres. What seems like harmless sunlight on a crisp day could be slowly bleaching your furniture.

Impact on Synthetic (PE/Resin) Rattan

Increased brittleness in extreme cold

PE rattan is far tougher than natural alternatives, but it’s not invincible. In freezing temperatures, the plastic weave can lose flexibility. Knock it too hard and it might crack under pressure.

Fading from UV exposure (even if less severe than natural)

Synthetic rattan holds up well, but it’s not totally fade-proof. Prolonged UV exposure, even in winter, can dull the colours. That stylish grey set might look a little more “dusty” come spring.

Accumulation of dirt, debris, and potential for algae/mildew

Leaves, rain, and garden grime have a habit of settling into the weave. Without a clean and cover, algae can take hold—and nobody wants a slimy armrest in April.

Water freezing in weaves, potentially causing stress

Rainwater can collect in the crevices of your set. When it freezes, it expands, subtly stressing the frame and weave. Over time, it can loosen joints or cause minor cracking.

Best Practices for Natural Rattan in Winter

The Golden Rule: Bring it Indoors!

Ideal storage locations (shed, garage, conservatory, spare room)

If you’ve got natural rattan, don’t leave it to battle the elements. Bring it into a dry shed, a garage, or even a spare room. A conservatory is perfect—warm, bright, and sheltered.

Ensuring items are clean and dry before storage

Wipe down every piece. Remove dirt, leaves, and any lingering moisture. Storing damp furniture is a recipe for mould.

Maintaining good air circulation in storage

Don’t stack it like a game of garden-furniture Jenga. Leave breathing space and avoid wrapping it in plastic sheeting—opt for breathable fabric covers instead.

If Indoor Storage Isn't Possible (Last Resort)

Thorough cleaning and drying

If it’s staying outside, start with a good clean. Use warm water and a soft brush. Then let it dry fully before any cover goes on.

Applying a protective sealant or oil (if suitable for the type)

Some natural rattan can be treated with a sealant or protective oil. Just make sure it’s safe for the material—some treatments can do more harm than good.

Using high-quality, breathable, waterproof covers

Cheap plastic covers trap condensation. Choose breathable, weatherproof ones that let moisture escape while keeping the rain out.

Elevating furniture to prevent ground contact and pooling water

If your set sits on a lawn or uneven patio, add rubber feet or risers. That little lift can prevent water from seeping into the legs.

Regular checks for moisture and damage

Check in occasionally. A quick lift of the cover and a glance can catch mould or damage before it spreads.

Best Practices for Synthetic Rattan in Winter

Can It Stay Out? (Usually Yes, with Caveats)

Understanding the material's cold resistance (check manufacturer)

Most synthetic rattan sets are sold as “all-weather,” but it’s always wise to check your product’s spec. Some brands are more frost-friendly than others.

Benefits of its UV and moisture resistance

PE rattan is designed to handle the UK’s unpredictable climate. It resists fading, shrugs off showers, and doesn’t swell like its natural cousin.

Recommended Winter Protection for Synthetic Rattan

Investing in durable, waterproof covers (essential for longevity)

A snug-fitting, high-quality cover is key. It protects from rain, frost, and even the odd bird visit.

Ensuring furniture is clean and dry before covering

Dirt left under a cover will stew all winter. A quick wipe-down now saves a weekend of scrubbing in March.

Regular brushing off of snow and ice

Snow build-up adds unnecessary weight. Use a soft broom to keep it clear—no scraping required.

Storing cushions indoors or in waterproof storage

Even “weatherproof” cushions benefit from being indoors. Store them in a dry box, garage shelf, or utility room.

Preparing Rattan Furniture for Winter Storage/Exposure

Deep Cleaning Before Winter

Removing all dirt, grime, and potential mould spores

Use a soft brush and soapy water. For stubborn patches, try white vinegar or a gentle cleaner. Rinse well and let it breathe.

Drying completely for several days

Moisture is the silent killer. Let your furniture dry thoroughly before covering or storing it.

Cushion and Fabric Care

Washing and drying cushions

Check care labels—most cushion covers can go in the washing machine. Wash on a gentle cycle, dry completely, and avoid storing them damp.

Storing cushions indoors in a dry place

Tuck them into an airing cupboard, loft, or covered storage box. Damp cushions = mildew mayhem.

Signs of Winter Damage and How to Address Them

For Natural Rattan: Cracking, splintering, mould, rot

Look for faded colour, flaky strands, or that musty smell. Clean gently, sand lightly, and re-treat where needed. In bad cases, it might be time for a replacement.

For Synthetic Rattan: Brittleness, fading, ingrained dirt

Cracks or stiffness may appear in cold-exposed pieces. Let them warm up before use, clean them carefully, and apply a UV protectant if needed.

Repair and Restoration Tips Post-Winter

Loose weaves? Use pliers and replacement material to rethread. Frames looking dull? A wash and coat of suitable polish brings back the shine.

FAQs about Rattan and Winter

Will my rattan furniture warranty cover winter damage?

Check the fine print. Most warranties only apply if the furniture is used and maintained properly—neglect often voids the cover.

What's the difference between rattan and wicker for winter?

Rattan is a material, wicker is a weave. You can have wicker furniture made from PE rattan (ideal for winter) or natural rattan (best kept indoors).

Should I remove snow from my covered rattan furniture?

Yes! Even with covers, heavy snow can put stress on the structure. A quick brush-off prevents strain and sagging.

Conclusion: Smart Winter Care for Your Rattan Investment

Rattan furniture—especially luxury garden furniture—adds style and comfort to outdoor spaces. But winter isn’t kind, especially to natural rattan. Whether it’s a resin weave or a handcrafted set, a little prep now will save you time and repairs later.

Clean it. Cover it. Store it right. And when spring returns, your garden set will be ready to shine again—no nasty surprises, just sunny afternoons and compliments all round.
