What makes a good raised bed – from modular shapes to optimal filling

A raised bed is much more than just a design element.
It brings structure to your garden, increases your yield, and makes gardening noticeably easier.

Creasteel raised beds combine design, functionality, and durability in a modular system. Here you can find out what really matters when it comes to a high-quality raised bed—from the shape and choice of materials to the right filling.

Modular raised beds – maximum design freedom

A good raised bed adapts to your garden—not the other way around.

The modular 80 × 80 cm elements allow you to create a wide variety of shapes:

  • Classic rectangular solutions
  • Generous U-shapes
  • Practical L-shaped layouts
  • Custom combinations for terraces or large garden areas

This allows you to make optimal use of your space and create clear, architectural structures in your outdoor area. The modular system also allows you to expand or reconfigure your raised bed at any time.

Robust materials – the basis for durability

The choice of material determines service life and stability.

Creasteel raised beds are available in two high-quality designs:

Steel with a patina finish

The natural patina develops its own character over time. This makes each raised bed unique.

Powder-coated aluminum

Modern, elegant, and particularly easy to maintain—ideal for clean, contemporary garden designs.

Both variants are:

  • Extremely stable
  • Weatherproof
  • Dimensionally stable even under high earth loads
  • Can be used outdoors all year round

Why metal is clearly superior to wood

Compared to wooden raised beds, metal offers decisive advantages:

  • No weathering or rotting
  • No swelling due to moisture
  • No annual maintenance such as oiling or glazing
  • Resistant to pests and fungi
  • No moisture absorption in the material

While wood loses stability over the years, metal remains dimensionally stable and durable. This ensures a significantly longer service life—without any maintenance.

Why a raised bed improves your garden

A high-quality raised bed offers you several advantages:

  • Back-friendly working thanks to raised planting area
  • Better soil quality through targeted layering
  • Higher yield through natural heat generation
  • Optimal drainage against waterlogging
  • Protection against snails and voles
  • Longer growing season due to faster warming of the soil
  • Clear structure and modern look

A well-designed raised bed is not only practical—it also enhances the quality of your garden in the long term.

Proper filling – the basis for healthy plants

The filling is crucial for nutrient supply and heat storage. A classic layering method has proven particularly effective:

1. Drainage layer (approx. 10–12 inches)

Branches, twigs, or wood chips form the base.
They ensure good aeration and prevent waterlogging.

2. Green material (approx. 15–20 cm)

Turned-over turf, leaves, or grass clippings promote decomposition and support natural heat generation.

3. Nutrient layer (approx. 10–12 inches)

Semi-mature compost or, alternatively, semi-rotted manure will provide your plants with nutrients in the long term.

4. Plant layer (approx. 25–30 cm)

High-quality garden soil mixed with mature compost forms the top layer for optimal growth.

This natural composting inside generates heat and reduces the need for watering.

Made for long-lasting gardens

A high-quality raised bed is a long-term investment.
It creates clean lines, increases yield, and remains stable and attractive for many years.
