Short version: sometimes, but it depends on what “wicker” you actually have, your winter climate, and how much protection you’re willing to add. In this guide, you’ll get a clear, practical answer (not vague advice), plus a simple checklist to keep your baskets and wicker pieces looking great through cold months. 🧺
If you’re storing seasonal items and want a neat indoor solution, a Wicker Storage Baskets setup can be a winter lifesaver (especially for blankets, throws, and accessories).
In a hurry? Here’s the honest summary ✅
- Natural wicker (rattan, reed, willow): not ideal outdoors in winter—moisture + freezing temperatures can weaken fibres fast.
- Synthetic wicker (resin/PE rattan): much more winter-tolerant, but still benefits from covers and airflow.
- The #1 enemy isn’t cold—it’s water trapped inside the weave + freeze-thaw cycles.
- If you can’t bring it inside: elevate it, keep it dry, use a breathable cover, and avoid sealing in condensation.
1) What “wicker” really means (and why it matters) 🧠
“Wicker” isn’t a material. It’s a weaving technique. That’s why two “wicker” items can behave totally differently in winter: one may survive fine, the other may start cracking or warping after a few wet, freezing nights.
Most people mean one of these:
- Natural wicker: willow, rattan, reed, bamboo—beautiful, warm, traditional, but more sensitive to moisture and temperature swings.
- Synthetic wicker: resin/PE rattan—built for outdoor use, more flexible in cold weather, less prone to rot (but still not “invincible”).
The key idea: winter isn’t one thing. It’s usually a combination of humidity, rain, frost, and repeated freeze–thaw cycles. Those cycles slowly push moisture in and out of fibres, and that’s what creates long-term damage.
2) What winter does to wicker: the 5 most common damage patterns ⚠️
A) Softening + loss of structure
Natural wicker is made of plant fibres. When those fibres repeatedly absorb moisture, they can soften. Over time, the weave can lose its tightness, and the piece starts to feel “loose” or slightly deformed. This is subtle at first—then one day you notice it doesn’t sit straight anymore.
B) Cracking after freezing nights
If moisture gets into the fibres and temperatures drop below freezing, water expands. That micro-expansion can cause tiny splits that become visible cracking later on—especially at stress points like corners and handles.
C) Mould and mildew (the slow killer)
Even if your winter isn’t “snowy”, damp air is enough to grow mildew, especially if an item is covered in a way that traps moisture. Mould often starts inside the weave where airflow is poor, so by the time you see it, it’s already spread.
D) Fading + dry-brittle fibres
People think winter sun is harmless. But UV still affects fibres, and cold air can dry them out. The result can be a weird combo: parts stay damp, parts get dry and brittle, leading to uneven ageing.
E) Metal frame issues (if your wicker has one)
Many wicker furniture pieces use a metal frame. Winter moisture can speed up corrosion. Once the frame starts to rust, it can push against the weave and cause stress, bulges, or breakpoints.
“Cold isn’t the main problem, trapped moisture is. If you keep wicker dry and ventilated, you already win 80% of the battle.”— Practical outdoor care rule (used by many patio specialists)
3) Natural vs synthetic wicker: quick comparison table 📊
If you want a simple decision framework, this is it. Think of it like choosing clothing for winter: wool behaves differently than polyester, even if both look “warm”.
| Feature | Natural Wicker (willow/rattan/reed) | Synthetic Wicker (resin/PE rattan) |
|---|---|---|
| Moisture resistance | Low–medium (absorbs water) | High (doesn’t absorb like fibre) |
| Freeze-thaw tolerance | Low (risk of cracking/weakening) | Medium–high (still benefits from cover) |
| Mould risk | Higher if damp | Lower, but can still grow on dirt/dust |
| Best winter approach | Indoor storage strongly recommended | Outdoor possible with good protection |
| What makes it last | Dry air + gentle cleaning + protection | Ventilation + cover + off-the-ground storage |
4) So… can you leave wicker outside in winter? ✅❌
If it’s natural wicker
If we’re being strict: you shouldn’t leave natural wicker outside all winter—especially uncovered. It’s not because it will instantly collapse, but because winter damage is cumulative. A few weeks might look fine. Then, months later, you’ll notice softness, cracking, or mildew stains that never fully disappear.
The “real world” answer: if you have no space indoors, you can leave it out only if you use a protective strategy: elevation, breathable covering, airflow, and a way to keep the weave dry.
If it’s synthetic wicker
Synthetic wicker can usually stay outside, but here’s the catch: many people protect it in a way that causes problems, like sealing it under plastic where condensation forms. The best strategy is protection + ventilation, not “wrap it like a sandwich”.
One more truth: if your winter is very wet (lots of rain, damp air), even synthetic wicker benefits from being moved under a covered area. The goal is to reduce daily “soak and dry” cycles that age the piece faster.
5) How to protect wicker outdoors in winter (step-by-step) 🧰
Here’s a practical routine that works for baskets, storage pieces, and wicker furniture. Treat it like winterising a car: you’re not doing one magic thing—you’re reducing risk across multiple points.
Step 1: Clean it (properly)
Remove dust and organic debris. Why? Because mildew loves dirt. Use a soft brush or microfibre cloth. If needed, a slightly damp cloth is fine, just avoid soaking natural wicker.
Step 2: Dry it completely
This sounds obvious, but most people fail here. If you cover wicker while it’s even slightly damp, you’re basically creating a mini greenhouse for mould. Let it dry in a ventilated space until it’s truly dry (including inside the weave).
Step 3: Elevate it
Never leave wicker sitting directly on wet ground, patio slabs that stay damp, or grass. Even a small elevation—wood blocks, a shelf, a pallet—reduces long-term moisture absorption.
Step 4: Protect from rain + allow airflow
Use a breathable cover (more on that below). If you can place it under an awning, porch, or balcony cover, do it. The biggest win is reducing direct rain exposure while still letting air circulate.
Step 5: Monthly 2-minute check
Once per month, lift the cover, check for condensation, wipe any moisture, and re-adjust ventilation. That’s it. This tiny habit prevents 90% of “surprise mildew” in spring. ✅
Pro tip for households: winter is when baskets become part of your indoor organisation. A Wicker Laundry Basket can look genuinely stylish in a bedroom or bathroom while keeping clutter invisible. 🧺✨
6) Covers: breathable vs sealed (the mistake most people make) 😬
When people ask “Can I leave wicker outside in winter?”, what they often really mean is: “Can I cover it and forget it?”
The problem is that many covers trap moisture. And trapped moisture is worse than cold. So here’s a simple cover rule:
The cover rule 🟦
Rain protection is good.
Condensation trapping is bad.
Quick cover comparison table
| Cover type | Good for winter? | Why |
|---|---|---|
| Breathable furniture cover | ✅ Yes | Blocks rain but lets moisture escape |
| Plastic sheet / cling film | ❌ Avoid | Condensation builds up fast → mildew risk |
| Tarp without ventilation | ⚠️ Risky | Better than nothing, but can trap damp air |
| Cover + small airflow gap at bottom | ✅ Best practice | Reduces condensation while staying protected |
If you only remember one winter tip, remember this: leave a small airflow gap so moisture can escape. A fully sealed cover can look “safe” but quietly damages wicker over time.
7) Cleaning before winter: what to do (and what to avoid) 🧼
Cleaning isn’t just about looks—it’s about preventing mould and odours. But with wicker, cleaning technique matters, because too much water can cause swelling or softness in natural fibres.
Safe cleaning routine
- Brush off dust and debris with a soft brush
- Wipe gently with a barely damp cloth
- Let it dry thoroughly (warm, ventilated room is ideal)
Avoid these mistakes
- Pressure washing natural wicker (forces water deep into the weave)
- Strong bleach or harsh chemicals (can weaken fibres and fade colour)
- Storing while damp (the fastest route to mildew)

8) Style + home tips: make winter storage look good 🏡✨
Here’s the underrated trick: instead of “fighting” winter storage, turn it into décor. People love wicker because it feels warm, natural, and calm, winter is actually the perfect season to bring that inside.
3 easy styling ideas
- Bathroom spa corner: rolled towels + candle + wicker basket = instant “hotel vibe” 🕯️
- Bedroom storage: throw blankets in a basket near the bed (looks intentional, not messy) 🧺
- Entryway organiser: gloves, scarves, keys in small baskets = no chaos at the door 🚪
Bonus: when you use wicker indoors during winter, it stays dry, stable, and lasts longer—so it’s both aesthetic and practical.

FAQ: Can you leave wicker outside in winter? (SEO-optimised) ❓
Is it OK to leave a wicker basket outside in winter?
If it’s natural wicker, it’s usually not ideal because winter moisture and freezing temperatures can weaken fibres over time. If you have to keep it outside, elevate it off the ground, keep it dry, and use a breathable cover with airflow.
What happens if natural wicker gets wet and freezes?
Water can get trapped in the weave. When it freezes, it expands and can cause tiny fractures in fibres. Over repeated freeze–thaw cycles, this leads to cracking, softening, and a loss of structure, especially around corners and handles.
Can synthetic wicker stay outside all winter?
Synthetic (resin/PE) wicker is generally more winter-resistant and can often remain outdoors. However, it still benefits from rain protection and ventilation—because mildew can still form on dirt or trapped condensation.
Should wicker be covered in winter?
Yes, but use the right type of cover. A breathable cover is best, because it blocks rain while allowing moisture to escape. Avoid sealing wicker under plastic sheets, which often creates condensation and increases mildew risk.
How do you prevent mould on wicker in winter?
Clean it before winter, dry it fully, store it in a ventilated space if possible, and avoid trapped moisture. If it must stay outdoors, elevate it and leave airflow at the base of the cover. A quick monthly check prevents surprises in spring.
Can I store wicker in a shed or garage?
Yes, often this is a great compromise. Just make sure the shed/garage isn’t damp and has airflow. If it’s humid, add ventilation or keep wicker off the floor to reduce moisture absorption.
Do I need to oil, varnish, or seal wicker before winter?
For most baskets, heavy sealing isn’t necessary and can sometimes trap moisture if applied incorrectly. The best “seal” is actually dry storage + airflow. If you’re treating wicker, always follow the product instructions and ensure the piece is fully dry before covering or storing.
Conclusion: The smart winter rule for wicker ✅
So, can you leave wicker outside in winter? If it’s natural wicker, the safest answer is: bring it inside if you can. If it’s synthetic wicker, it can often stay out—but your protection method matters more than your optimism.
The winning formula is simple: clean → dry → elevate → cover (breathable) → ventilate. Do that, and you’ll dramatically extend the life of wicker through the harshest months. ❄️🧺
