The Pros and Cons of Fiberglass Planters

Fiberglass planters are a durable and versatile planter material that can easily take plant designs to the next level. Though it’s already a fairly popular planter material, we often encounter a lot of questions about whether it’s the right choice for an installation.

If you’re trying to decide if fiberglass planters are the right choice for your plant displays, we answered some of our most frequently asked questions and put together a list of pros and cons about this adaptable planter material.

What are fiberglass planters made of?

Fiberglass planters are made of sheets of spun glass fibers held together with a polymer resin.

How are fiberglass planters made?

To make a fiberglass planter, a mold is filled with resin then covered in sheets of fiberglass. The resin and fiberglass sheets harden, and create the planter structure. The planter is then removed from the mold, sanded and painted. After the paint dries, it is ready to ship!

What makes a quality fiberglass planter?

Though this process seems simple, some vendors will cut corners to reduce costs at the price of planter quality. As time goes on, low-quality planters start to look worn and those shortcuts become more apparent. This is why it’s important to source planters from companies that specialize in fiberglass planters that are fully dedicated to the finishing process.

The tell-tale signs of a low-quality planter are:

  • Weight: If a fiberglass planter is overly heavy, the manufacturer likely added fillers to the resin.
  • Rough Surface: Bumps, waves, and imperfections in the finish often indicate poor-quality construction or that shortcuts were taken during finishing.

Pros of Fiberglass Planters

Indoor and Outdoor Usage

The durability of fiberglass planters make them a versatile pick for both indoor and outdoor usage. 

Outdoors, fiberglass planters with a proper finish are able to withstand all four seasons and inclement weather. An automotive-grade finish helps to prevent wear and discoloration from UV rays, rain, snow and sleet.

Additionally, a majority of outdoor fiberglass planter installations have drainage holes to allow water to seep out and ensure plants aren’t sitting in moisture. This also prevents additional damage to the planter, as extra water freezing and expanding can crack and break the fiberglass.

For indoor usage, the automotive-grade finish helps fiberglass planters stand up to wear and tear from foot traffic and natural oils from curious hands. Drainage holes aren’t typically needed for indoor installations. Most interiorscapers will frequently choose to keep fiberglass planters sealed to keep moisture contained and help protect client floors.

Lightweight

Compared to stone, concrete, ceramic and terracotta planters, fiberglass plant pots are incredibly lightweight. The fiberglass fibers and resin at the right consistency create a planter structure that is easy to move even in extra large dimensions.

Weather-Resistant

Quality finishes on fiberglass planters ensure they are able to withstand harsh weather conditions during spring, summer, fall and winter. Snow, sleet, rain, and excessive sunshine are no match to a fiberglass planter’s durability.

UV Resistant

A fiberglass planter paired with an automotive-grade finish will resist cracks and fading colors from UV rays. This type of finish keeps fiberglass planters looking fresh despite any harsh sunlight.

Low Maintenance

Fiberglass planters require very little maintenance. They can be left without care for a significant amount of time in both indoor and outdoor conditions. However, an occasional cleaning and wax can help to keep them looking their best.

Durability

Fiberglass planters are made to last. Whether placed indoors or outdoors, fiberglass plant containers are able to withstand adverse weather, foot traffic, UV rays and more while offering an attractive foundation to plant designs.

Color Palette Availability

Match any interior or exterior design with a wide selection of standard available colors. If you need to match a particular color scheme, some companies specialize in offering custom painted planters to match a RAL color code.

Cons of Fiberglass Planters

Initial Price

One of the biggest drawbacks of fiberglass planters is their initial price. Fiberglass planters can be a pricier choice, especially when compared to plastic planters. However, the overall durability of fiberglass planters often makes an initial investment worthwhile. 

Fiberglass planters are constructed to last year after year, while plastic plant pots will frequently break, crack, fall apart or fade after one season. Instead of spending funds replacing plastic planters every year, a slightly larger investment in fiberglass planters offers a foundation that lasts for much longer.

If you’re looking for planters that are durable, beautiful, high quality and low maintenance, fiberglass planters are truly the best option out there. Though plants should certainly take center stage, a fiberglass planter is an amazing accent for any residential or commercial plant design.
