Corten steel planters are more than just planting containers; they are dynamic design elements that change over time. They create a rich rust-coloured texture (while resisting corrosion) and are suitable for a wide range of outdoor styles, from modern to traditional. In this article, we will discuss how to use their aesthetic and functional advantages to enhance the style of outdoor spaces.

Why Corten Steel Planters are a Garden Essential

Durability For All Kinds Of Weather

Evolving Aesthetics

Low-Maintenance Benefits

The outdoor metal planter box is virtually maintenance-free: there is no need for painting, sealing or frequent renovations - the naturally occurring layer of rust is the best possible protection.

Choosing the Right Corten Steel Planter: Shape and Size

• Corten Trough Planters: suitable for defining borders, planting herbs or creating hedges. The long and low shape can outline the neat edges and is often used along walls or walkways.
• Corten Cube Planters: Ideal for structural planting, embellishing shrubs or creating a neat layout, these planters inject a modern architectural feel into outdoor spaces and can be sized to create a sense of rhythm.
• Round Corten Planters: Ideal for individual feature planting, as a focal point or to soften corners, the curved shape balances out angular landscapes and allows greenery to spread naturally.
• Tall Planters: Ideal for adding vertical visual effect, filling narrow spaces or creating eye-catching planting landscapes without taking up too much floor space, suitable for placing on either side of doorways or along walkways.
• Raised Garden Beds: both beautiful and practical, convenient for planting herbs, vegetables or flowers, easy to take care of, without affecting the overall style.

How To Design a Corten Steel Planter?

Strategic Placement

• Focal point: Use large round or tall Corten planters as the centrepiece of a garden or terrace rest area.
• Enhance frontage appeal: place long Corten planters along the driveway or pair square planters on either side of the front door to greet visitors.
• Zoning the space: divide outdoor ‘functional areas’ (e.g., dining and lounging areas) with planters to create a sense of flow and privacy.
• Responding to climate exposure: utilise its durability by placing it in exposed areas such as windy and rainy areas, where other materials may struggle to withstand these environments.

Creative Ways To Combine

• Group placement: Mix different sizes and shapes (e.g., tall cylindrical vs. low rectangular metal planters) to enhance visual hierarchy. 3-5 planters in a group create a well-designed effect.
• Layered displays: Place planters at different heights (e.g., low walls, planters) to create a staggered hierarchy of greenery.
• Privacy barrier: Plant climbing plants (e.g. ivy, jasmine) in tall metal planters to form a natural partition to separate different spaces.

Plant Mixing Tips: Maximising Visual Impact

• Focal point plants: Choose plants with eye-catching shapes and distinctive colours (e.g. red dragon's blood tree, ornamental grasses) to serve as the visual centre.
• Filler plants: fill in the gaps with compact, low-growing plants (e.g. pansies, geraniums).
• Dangling plants: let vining plants (e.g. creeping jenny, purple-flowered edelweiss) hanging down from the edge of the pot to soften the lines.
• Seasonal rotation: change plants according to the season (tulips in spring, succulents in summer) to keep the space always fresh.

Corten Steel Planter Maintenance Tips

• Regular cleaning: Rinse with water to remove dust and fallen leaves, and avoid using harsh cleaners to prevent damaging the rust layer.
• Ensure drainage: Check that the drainage holes are clear to prevent water from accumulating and affecting plant growth and the bottom of the planter.
• Preserve the natural rust layer: Do not paint or seal your garden planter, the naturally occurring rust colour is part of its charm.
