Winter Care for Fiberglass Planters

For year-round displays, it’s crucial to select planter materials that are able to withstand the elements. Fiberglass planters are frequently chosen for many commercial applications due to their ability to be used through every season. Though these planters are incredibly durable and require very little maintenance, here are a few things to keep in mind when purchasing and maintaining fiberglass planters during the winter months.

Can Fiberglass Planters Stay Out in Winter?

Yes. Fiberglass planters are able to withstand extreme hot and cold temperatures, and typically will not crack or break under those conditions. However, you’ll want to make sure your planters are prepared to withstand those temperatures and elements. 

Purchasing fiberglass plant pots meant for outdoor use is key. Commercial-grade fiberglass and thoughtful construction help to ensure exterior planters last through the elements.

A proper finish will also help to maintain the container’s luster. Every NewPro fiberglass planter has an automotive-grade finish applied that is UV resistant, and made to withstand the elements.

Finally, drainage holes are essential to resist against cracks and breaking. Freezing water pooled in the bottom of a fiberglass planter may expand, and cause the planter to crack and break. Ordering planters with holes pre-drilled is the easiest way to make sure your planters are ready for exterior display. 

Winter Care for Fiberglass Planters

Because fiberglass planters are so low maintenance, there’s not a lot to do to make sure they stay in good shape during the winter months. However, consider a few general care guidelines to make sure they stay in good condition throughout the year.

  • Clean Periodically: Dirt, debris, snow, salt, and ice can build up on planter exteriors. We put together some step-by-step instructions on how to clean fiberglass planters, but in general, use mild soap and water and a soft sponge or cloth to wipe off any accumulation.
  • Look for Scratches and Chips: Passing snow shovels or foot traffic may cause scratches or chips in the painted fiberglass finish. When water or debris gets under the finish, it won’t cause structural damage, but it may diminish the appearance of the planter. For small scratches, simply cover with some matching paint. For larger chips, sand and fill with an epoxy. Sand flush to the surface, and cover with some matching paint. Contact us if you need some matching paint. It may look different than the rest of the planter at first, but it will age and match over time.
  • Wax: Use a quality wax every so often to further protect the finish on exterior fiberglass planters.
