, 4 min reading time
Planters, planter boxes and outdoor pots have become an essential part of modern gardens, terraces and balconies. They not only add greenery, but also create structure, privacy and atmosphere. In practice, however, planters and pots are often chosen or placed incorrectly, leading to poor drainage, limited root growth or unnecessary maintenance. In this comprehensive guide, you’ll learn step by step how to choose the right planter or planter box, how to install and assemble it correctly, and how to use and maintain planters for long-term healthy plants. This way, your outdoor planters and outdoor pots stay attractive and functional for years to come.
What is a planter and when should you use planter boxes?
A planter (also known as a planter box or plant container) is a fixed container used for flowers, plants, ornamental grasses or small shrubs. Compared to individual outdoor pots, planters offer more volume, stability and a cleaner overall look. Planter boxes are often used for linear planting, separation or as a visual feature, while outdoor pots are more suitable for flexible and seasonal planting.
Step 1: Choosing the right planter
1) Choose the right material
- Polyester planters: lightweight, sleek and colourfast. Ideal for balconies, roof terraces and modern outdoor spaces.
- Aluminium planters: rust-free, low maintenance and modern. A strong choice for entrances and terraces.
- Corten steel planters: robust and characterful, with a natural rust layer that protects the material.
- Wooden planters: warm and natural in appearance. They require periodic maintenance but suit green gardens perfectly.
2) Determine the right size
- 40–50 cm: suitable for compact planting and smaller outdoor spaces.
- 60 cm or larger: more root space, better moisture retention and healthier plants.
- Long planter boxes: ideal for privacy, borders and linear planting.
3) With base or without base?
- Planters with a base: required on paving, concrete and roof terraces.
- Planters without a base: only suitable when placed directly on natural ground.
Step 2: Installation, assembly, use and maintenance of planters
Installation
- Choose the final location before filling the planter.
- Ensure a level and stable surface.
- Check that rainwater can drain away properly.
Assembly
- Attach feet or spacers if required.
- Add a drainage layer of approximately 10 cm using clay pebbles or gravel.
- Cover the drainage layer with a permeable liner or fabric.
Use
- Fill the planter with an airy substrate suitable for the plants.
- Place the plant at the correct height.
- Water until excess water can drain away.
Maintenance
- Check soil moisture regularly.
- Remove dead plant material and inspect drainage openings.
- Clean planters periodically.
- Protect sensitive plants during frost.
