How to Choose the Right Outdoor Planter for Your Balcony or Terrace

When designing a balcony, terrace, or garden, choosing the right containers is a key step. Far more than a simple pot, an outdoor planter is a true decorative element that adds structure to your space and enhances your plants. But with the vast array of shapes, materials, and features available, it can be hard to know where to start. This guide is here to shed light on the essential criteria and present our selection of the best models to help you make the right choice.

Key Criteria for Choosing Your Outdoor Planter

Before you take the plunge, let's review the few points that will make all the difference for the longevity of your setup and the health of your plants.

1. Material: Balancing Aesthetics and Durability

The material is arguably the number one criterion. It determines not only the look but also the durability. New-generation plastic planters have come a long way. A far cry from the models of the past, they are now treated to resist UV rays and frost, making them a perfectly reliable frost-proof option for our climate. Being lightweight, they are easy to move, which is a definite advantage for a balcony planter or a terrace planter. Modern finishes, like the stone effect, successfully combine the practicality of plastic with a stylish and natural aesthetic.

2. Functionality: The Water Reservoir

Do you sometimes forget to water your plants or often go away for the weekend? A planter with a water reservoir is the solution you need. This clever system stores excess water at the bottom of the container and gradually releases it to the plants through capillary action. The result: the moisture at the root level remains constant, you can water less frequently, and your plants no longer suffer from water stress, even during a heatwave.

3. Size and Shape: A Matter of Space and Plants

The size of your flower box should be considered based on the available space, but also on the needs of your plants.

  • A large planter is ideal for structuring a terrace, creating a plant-based partition, or housing shrubs that need room for their roots.
  • The rectangular planter remains a timeless classic for dressing up a windowsill or defining a balcony.
  • The tall planter plays with verticality to highlight certain plants and create an eye-catching focal point.

Your Questions, Our Answers

How do I choose the size of an outdoor planter?

The ideal size depends on two things: the space you have and the plants you plan to put in it. For a small balcony, a rectangular planter of 50 to 80 cm is often a good choice. For a terrace, a large planter of 80 L or more can accommodate a shrub or serve as a plant-based privacy screen. Always remember to check the space needed for proper root development before you decide.

What are the benefits of a planter with a water reservoir?

Simply put, it allows you to water less frequently. The excess water is stored and continuously made available to the roots through capillary action. It's the perfect system for summer, if you go on holiday, or if you tend to forget to water. It ensures consistent hydration, promotes healthy growth, and prevents the soil from drying out.

How can I protect a plastic planter from frost?

Quality plastic planters, like those from the EDA brand, are now designed to be frost-proof. However, it's mainly the roots that need protection. In case of a deep freeze, a few simple steps can make all the difference: mulch the soil surface, wrap the pot in a winter fleece, or raise it off the frozen ground with blocks. Finally, check that the drainage hole is not clogged so that water doesn't stagnate and freeze, which would be fatal for the roots.
