Let’s get to it!

But the first thing first 

Is it fibreglass or fiberglass?

According to wikidiff,  fiberglass is the US spelling of fibreglass.

Since I live in the US, I will be using the word fiberglass in this article. 

And now the next question arises:

What are fiberglass planters made of, exactly?

Fiberglass planters are made of composite material formed from fibers of spun glass that are held together with resin.

Sometimes fiberglass is called glass reinforced plastic.

Some manufacturers are now adding different materials  to create a better planter texture.

For example, it is possible to get  fiberclay planters made of a mix of fiberglass and clay,

or fiberstone planters in which fiberglass is combined with about 60% finely ground stone.

How fiberglass planter is made

  1. Making of a fiberglass planter or pot starts with the mold. The resin is mixed and poured into the mold and then brushed on the mold walls.
  2. Sheets of fiberglass are placed in the mold over  the resin layer to give the planter structure.
  3. Then a chemical reaction occurs: fiberglass and resin warm up and harden.
  4. After 24 hours the planter is taken out of the mold.
  5. It gets sanded, cleaned, and painted.

You can watch the whole process of making a fiberglass pot in this YouTube video created by Spruce Home and Garden – a maker of fiberglass planters.

 

Fiberglass planter advantages from a design point of view

What I like the most about fiberglass planters is the range of design options to choose from, because fiberglass pots can be made to mimic any material.

So, depending on your decor needs or style of your garden  you can get a fiberglass planter that looks like wood, terracotta, cement, stone, ceramic. It can be glazed, shiny, slick and modern, or dull and aged – the possibilities are endless.

Your new fiberglass planters will look great in a container garden and kitchen garden, on a patio, balcony, rooftop, front porch, outdoors or indoors.

They are an ideal solution for commercial applications too. If you need long lasting great looking planters in the front of your restaurant or shop – fiberglass planters are a great maintenance free choice.

You might wonder though, why wouldn’t get a terracotta or cement planter in the first place instead of setting on an imitation?

That’s because the fiberglass planters have many other great benefits.

Benefits of fiberglass outdoor planters 

  • long lasting
  • lightweight which makes them easy to move – great choice for a container garden and especially for rooftop gardens
  • durable
  • don’t require maintenance
  • weather resistant
  • won’t rust
  • won’t crack from temperature changes
  • nonporous, can actually prevent water evaporation and minimize soil moisture loss
  • color will not fade from sun
  • can be left outdoors during frost, so don’t require special storage over winter
  • you can leave soil in a fiberglass pot over winter.

So, it seems everything screams YAY for fiberglass pots. Don’t you think?

Yet, there are some

fiberglass outdoor planter drawbacks

  • fiberglass planters trap heat in hot weather (because they are non porous) which leads to overheating of the soil on hot sunny days. This can bake plant roots. 
  • fiberglass pots can crack when dropped
  • some of them are quite pricey
  • fiberglass containers are not ideal for growing tall vegetables – like tomatoes, peas, green beans, because they might topple over if you insert support (stakes, cages) for plants
  • small fiberglass pots may get blown by heavy winds and need to be sheltered in severe weather
  • many fiberglass containers come with no drainage holes.

How to overcome some disadvantages of fiberglass pots

To avoid the possibility of plant roots getting baked in the fiberglass pot in hot sunny weather choose white or very light colored planters.

You can also line the insides of a fiberglass container with thermal fabric if you are growing decorative plants in it. If you are planning on growing vegetables in this planter, be sure that the liner you are using is safe for food growing.

To solve the tipping over issue, you can place rocks in the bottom of the planter.

As for drilling a drainage hole – it’s easily done. To see instructions, scroll down and find the useful tip “How to make a drainage hole” in my article about container gardening.

Who should avoid fiberglass outdoor planters?

If you live in a desert or tropical climate and need a pot that will be exposed to sun rays all day long, then maybe this kind of planter is not the best choice for you (and clay pots will be a more suitable option).

Are fiberglass planters toxic?  Is it safe to grow vegetables in fiberglass planters?

After scouring the internet I didn’t find any mention of possible toxicity of fiberglass planters.

Unlike plastic planters, where color pigment that can be toxic is mixed with plastic, the paint and glaze on fiberglass planters  are applied to the outer surface of the planter.

Most likely, fiberglass planters are suitable for growing dwarf fruit trees, blueberry bushes, strawberries or veggies in them.
