Can fiberglass planters withstand freezing soil? Can fiberglass planters stay out for winter? Are fiberglass containers truly frostproof? The answer to all these questions is a resounding yes!
Fiberglass is one of the most durable and hardy materials out there for planters, they do not rust, they are frost and heat resistant, and there is no fear of breaking.
In fact, fiberglass is often used to make automobile parts, building materials, boat hulls and more. You can be assured that they are the best material at withstanding cold temperatures.
Vietnam CDM’s outdoor planters not only keep outdoor plants safe throughout winter, they also look good doing it.
However, not all planter materials are made equal. Many are not frost resistant; they cannot survive snow and have to be taken into the house or a warmer area during the cold season.
Read on to learn more about how to protect commercial or residential gardens during cold weather, and how to winterize planters.
Who Is This Advice For?
Many of our clients procure planters and plant pots for industries that require outdoor landscaping such as hotels, campuses, and food & beverage establishments.
The following advice is to help commercial buyers decide which planter material is the best, and how your customers can protect their investment with the right winter planter maintenance. Feel free to share our advice with them too!
What Kind Of Planters Can Withstand Freezing Temperatures?
There are so many different types of containers out there, metal pots, ceramic pots, wooden pots, terracotta pots, and more!
To withstand the cold weather, frost, and snow, the materials must not break apart when soil or water freezes in the plant pots. When the container break apart, the cold will have access to the plant roots, affecting its health. When spring comes around, not only will the pot need to be replaced, the plant likely would as well.
To avoid unnecessary expenditure and heartbreak, we share expert insights below on which material is the most suitable for winter.
1. Fiberglass Planters
Fiberglass planters are by far the best choice – not only will they survive the ice and snow, but they will also continue to look great and keep your plants healthy for many years to come.
Generally, you need commercial-grade fiberglass planters to get the benefits of a professional product such as the stunning visual aesthetics that don’t deteriorate over winter.
Our planters are made to thrive in all elements, from spring, summer, fall, to winter. Not only do we use naturals resins with our fiberglass to create a durable product, but our planter’s durable finish is also achieved through the application of top-quality marine and automotive-grade paint and top coating.
The best part about using fiberglass planters during winter is that they need little maintenance and care even when left outside. Now, what about other containers?
2. Will Glazed Pots Crack in Winter?
Glazed pots are earthenware pots with a coating of liquid that is fired in a kiln to create a glaze on the outside. Generally, these are ceramic pots, terracotta pots, and clay pots finished with an attractive glaze.
Earthenware is made of permeable material – this means that it is porous, absorbs water, and will freeze during winter, causing the pot to break easily.
Glazed pots fare better than unglazed pots, however, this protective layer is often only on the outside, leaving the bottom and inside of the planter vulnerable.
Leaving these pots in your yard through winter is a huge risk, they might survive one winter, but probably not two. It is better to move them indoors.
3. Will Concrete Planters Survive Winter?
Cement or concrete containers, as a general rule, will not perform as badly as clay pots during winter.
Concrete is a frost-resistant material, except when it gets wet! This can happen as the pot ages and it develops small openings and holes in its surface, this allows moisture in, causing the pot to split. Another issue is the soil freezing in the container, this will expand, and can also cause the planter to crack.
Concrete planters are heavy and hard to move indoors every cold season. The best way to avoid cracking them is to remove half the potting soil during winter, which will allow some space for expansion.
4. Are Plastic Pots Winter-Proof?
In general no, plastic pots do not do well under wintery conditions, especially in the long term.
The good thing is that plastic pots do not absorb water. However, similar to concrete, they can suffer damage when the soil they house freezes and expands. The planter will then crack.
The issue with using a plastic container for your garden is that plastic is susceptible to ultraviolet rays emitted by the sun. The plastic planters will become more fragile and brittle. This can cause the pot to crack apart. Plastic containers often only last for two to three years.
5. How About Other Materials?
What about wood, stone, or metal outdoor planters?
Wood has a natural elasticity and hence can tolerate frozen soil. However, the continuous cycle of freezing and thawing of the soil can damage the planter. All wood pots, even those that are treated, will rot with repeated exposure to moisture. It is best only take out half the soil if you are leaving it outside for winter.
A stone container is clearly made from a durable, highly weather-resistant material. However, it is heavy, hard to handle, and does not suit the look of most modern gardens. If using such planters, make sure they have drainage holes for water to flow out of during winter.
Metal planters are unsurprisingly very resistant to frost; the soil can freeze in them with no issue. However, metal is prone to rust and oxidization over time.

Notes on Winterized Planters
When winter comes along, it is always a good idea to protect your frost-proof planters and plants, to ensure they thrive in the cold weather. Check out our tips on how to protect pots below!
Avoid Waterlogging in Cold Weather
The ground can freeze during winter, which can cause water flow issues for planters, trapping water inside with the soil and roots.
Lift the pot above the ground during these months to ensure water can exit through the drainage holes. Use pot feet, small tiles, or even wine corks, to elevate the pots during winter.
Insulate The Plant Pots
Keeping planters warm is key during cold conditions. A few layers of bubble wrap will help ensure that the pots are protected against the freezing winds and reduce
s frost access to the plants.
Winter Care For Fiberglass Pots
Even though fiberglass pots are low maintenance and require no special upkeep. A little care will go a long way. Here are some tips.
Wipe and clean the exterior with mild soap and a soft cloth. This will protect the finish on the pots and maintain its luster.
For added protection and a glossier finish, apply a coat of high-quality marine-grade wax twice a year. The extra effort is worth it, as the wax contains sealers that fill microscopic holes in the finish coat, keeping it brand new.
The Best All-Season Choice – Fiberglass
