Best Indoor Fiberglass Planters Guide: Our Top Picks

We all love our plants, whether they are inside our homes or out in the yard. Yet, these plants can be made even more beautiful with the best fiberglass planters.

Fiberglass planters make a lot of sense. You can easily pot your plants and place them indoors. They also allow you to have a beautiful accent for your yard and give your small trees and shrubs more soil without having to plant them into the ground.

Not only that, if you have ever tried to move your planters and pots around, you know that terracotta pots will break your back, while the bottoms of plastic ones are always in danger of breaking. These are not problems with a fiberglass planter.

As you can guess, there are a lot of situations where a fiberglass planter is all you need. And here are the ones that we recommend for you regardless of what you need right now.

The Best Fiberglass Planters Available Now

Fiberglass planters can make a lovely addition to your home’s décor. If you have plants inside the house, then forget about other materials when it comes to your pots. Fiberglass planters are especially useful when you require bigger containers for your plants.

This is because it might be very difficult to find something made with a different material. For instance, tall ceramic planters are prone to breaking and can be very heavy. These are not issues when you have a fiberglass planter.

Conversely, fiberglass planters also make sense outdoors because they can pretty much stand up against the elements. Their colors don’t fade even when exposed to sunlight.

So depending on where you plan to put these planters, we have listed down the best for you. On top of that, we have selected the best products according to their style, function, and design.

Question: Why should you use fiberglass planters anyway?

Answer: Fiberglass planters are made with plastic that is reinforced with glass. As such, these planters are lightweight and durable. If you want to design your garden in a certain way, these planters are also a good idea because they can mimic any material. Fiberglass planters are also:
• Weather-resistant, so it’s safe from extreme heat, freezing, and other elements
• Non-porous, so moisture is not lost.
• Color will not fade over time.
But there are some disadvantages to fiberglass panters as well. For one, the non-porous material means that you should always have a drainage hole.
Some fiberglass planters can also be expensive.

Question: Can you leave fiberglass planters outside during the colder winter months?

Answer: We’ve all had that heartbreaking realization that some planters made of terracotta, ceramic, or other porous materials freeze and then break in the winter. These materials allow and hold water in, which then freezes and expands in the cold.

Fiberglass planters are different. Harsh sunlight, cold winters, rain, ice, or snow should not affect it negatively. With the right kind of fiberglass planter, you don’t have to worry about the elements cracking or breaking it down. The material will not deteriorate even when you keep it outside.

Question: How do you maintain a fiberglass planter?

Answer: We know that fiberglass planters are hardy and can tolerate a fair amount of abuse. But you do have to care for it once in a while.

Cleaning Your Fiberglass Planter

Dirt and dust can easily accumulate on your planter over time. As such, you should make it a habit to wipe it down with mild soap dissolved in just enough warm water using a soft sponge.
Be sure to thoroughly rinse off the soapy water when you’re done. If you’re cleaning an indoor fiberglass planter, you can use a damp cloth instead of a soft sponge.

Take Care of the Little Cracks and Chips

Fiberglass planters can be chipped or cracked over time. It’s not really that big of a problem with this kind of planter.
However, leaving these cracks open might mean water and moisture getting under the protective coating. As time passes, the protective coating chips and flakes off. Also, if your planter has some mineral buildup, be sure to remove these as soon as you spot them.
The thing is, sometimes, the repair is easy. For example, you can touch up small scratches with a coat of paint. If the scratch, dent, or chip is deeper, you can just sand the area and then fill it out with epoxy before painting over the damaged part.

Waxing Your Fiberglass Planter

Giving your planter a coat of wax will help make it more durable, with the welcome side effect of making it look glossy and better protected from the elements. Coating it with wax will also make your planter less susceptible to dust and dirt, so you clean it less frequently.
You can use products like the Star Brite Premium Marine Polish, which is formulated for fiberglass and other similar surfaces. There are also sprays that can help you protect your fiberglass planters. A product like the 303 Marine UV Protectant Spray helps prevent cracking and fading while also repelling dust, dirt, and stains without the greasy feeling.

Other Tips:

• Handle your fiberglass planters with care. If you need to move it around, you should first empty it and move it safely rather than push, tug, or twist the planter.
• Avoid using harsh chemicals and abrasives to clean persistent dirt as these can strip the planter of its protective coating. A tough abrasive like steel wool can also leave deep scratches on your planter.
• Keep them off the ground. Fiberglass planters should have feet or a platform to keep them off the ground. There is a possibility that the planter will sink if you put it on grass or dirt. This will result in the planter having problems with drainage.
