Concrete planters are a stylish and durable addition to any garden or patio. However, even the hardiest concrete can suffer cracking, spalling, and moisture damage when winter arrives. Fortunately, with the proper preparation, you can protect your handmade concrete pots from the harshest weather.
In this guide, we’ll share expert advice on winterproofing concrete planters so they survive the season beautifully.
Why Winter Care Matters for Concrete Planters
Concrete is a porous material, meaning it absorbs water. When this trapped moisture freezes, it expands, causing cracks, crumbling, or surface damage. Taking steps to winterproof your planters can prevent:
Freeze-thaw damage
Waterlogging and root rot
Weakened structural integrity
Unsightly cosmetic deterioration
Choosing the Right Concrete Planters for Winter
Begin with quality craftsmanship. Look out for features that make a difference in winter:
Built-in drainage holes
Substantial wall thickness
Sturdy, frost-resistant design
Raised bases or the ability to use pot feet
Preparing Your Planters Before the First Frost
Prevention is key when it comes to winter damage. Before temperatures drop:
Empty and thoroughly clean planters using mild soapy water
Remove limescale and mineral deposits with a vinegar solution (1:1)
Allow them to dry out completely
Apply a breathable, weatherproof concrete sealant
Use pot feet or bricks to lift them off cold, wet ground

Planting Tips for Winter-Ready Arrangements
If you plan to keep plants outdoors during the winter:
Choose hardy plants like heather, hellebores, or ornamental grasses
Place a layer of gravel at the bottom to improve drainage
Use a compost that’s resistant to frost
Water sparingly—especially before a cold snap—to avoid ice damage inside the container
Best Placement for Winter Protection
Where you position your planters can significantly affect their longevity in cold weather:
Move containers closer to house walls or under sheltered areas
Elevate using pot feet or timber to prevent freezing to surfaces
Avoid placing them in waterlogged or low-lying spots
Storage Solutions for Smaller Planters
If your planters are small or not currently in use, store them safely:
Keep indoors if possible—in a shed, garage, or greenhouse
If storing outside, turn them upside down and raise them off the ground
Cover with breathable horticultural fleece (avoid plastic, which traps moisture and causes damage)
Stylish Winter Planter Ideas
Winter doesn’t mean your garden has to look bare. Create visually appealing displays by:
Combining evergreen foliage with pinecones, berries, or twigs
Adding fairy lights for a warm, festive glow
Using dried flowers and seed heads for a natural, rustic look
What to Do If Your Planter Already Has Cracks
If your planter has already suffered some damage:
Treat fine cracks with a concrete repair compound
Seal the exterior to prevent further water ingress
Repurpose damaged pots for decorative use, avoiding heavy plant loads

Regional Tips: Colder vs. Milder Climates
Adjust your care based on the severity of your region’s winters:
In colder areas (e.g. Scottish Highlands, northern England), storage and sealing are essential
In milder southern regions, good drainage and sheltered placement may be sufficient
Pro Tip: Create a Seasonal Maintenance Checklist
Set a reminder every autumn to inspect and prepare your planters. Regular checks can prevent costly damage and keep your garden looking its best year-round.
Conclusion
Concrete planters offer timeless beauty and robust design but need a little TLC to survive winters. By following these practical tips—cleaning, sealing, storing, and placing with care—you’ll ensure your containers last for many years.
Winterproof Concrete Planters: Frequently Asked Questions
1. Can I leave concrete planters outside during winter?
Yes—provided they are sealed and elevated to prevent water absorption and freezing. Otherwise, move them indoors for safety.
2. How should I seal a concrete planter?
Use a breathable, water-repellent sealant. Apply it to a clean, dry surface and allow it to cure fully before exposure to rain or frost.
3. What plants are suitable for winter pots?
Top choices include hellebores, evergreen grasses, ivy, pansies, and dwarf conifers.
4. How can I stop my planter from cracking in the cold?
Ensure proper drainage, avoid overwatering, seal the concrete, and keep the pot off direct contact with frozen ground.
5. Should I cover planters with plastic during winter?
No—plastic traps moisture, which can cause damage. Instead, use breathable materials like fleece or hessian to protect from frost while allowing airflow.
