Fiberglass planters are robust and also look good. It's only annoying if the hardware store doesn't have any copies in its range. In this case, the skilled gardener simply builds his own fiberglass plant pot. With the instructions on this page, you can also build your own.
How do I build a fiberglass planter myself?
To build a fiberglass planter yourself, you first need a concrete blank as a mold. Attach cut fiberglass panels around the blank, roughen the surface for a rustic look, and protect the interior with foil and drainage.
Industrial production of a fiberglass planter
- Production of a positive model of the plant pot made of wood or plastic (identical to the later product)
- Making a negative model from fiberglass
- Fine polishing and polishing of the model
- Painting with polyresin
- Stabilization by attaching three-layer fiberglass mats
- Removal of the mold after around 24 hours
- fine touches
- Painting and re-polishing
- High-gloss vessels are painted and polished four times
The material determines the robustness
High-quality models are made of pure fiberglass and can therefore easily be left outdoors in frost. However, for cost reasons, many manufacturers add stone chips to the material. These soak up water when it rains and crack when it freezes. This means that expensive fiberglass plant pots are really worth the money.
Build your own fiberglass plant pot
Of course, it is not possible for you to carry out a similarly complex production in your home garden as with the procedure described above. For your self-made fiberglass plant pot, you will need a raw form, for example made of concrete. You can get the required fiberglass for the cladding at any hardware store. Cut the panels to size and attach them around the blank. No one will be able to tell the difference. To create a rustic style, lightly roughen the material with sandpaper. To increase the longevity of the plant pot, you should line it with foil before planting. Use drainage to ensure that no waterlogging occurs.
