A tree collar is a protective and decorative ring that surrounds the base of a tree trunk where it meets the ground. In simple terms, a tree collar creates a clean, finished edge around your tree while helping to protect its base from lawn tools, weed growth, and moisture imbalance. Tree collars can be made from timber, metal, composite, stone or recycled materials, and they are widely used in Australian gardens, courtyards, parks and streetscapes for both practical protection and aesthetic enhancement.
Here’s why Australians love tree collars: they blend functionality with design, turning what can be an overlooked part of landscape into a polished, tailored feature — ideal for modern outdoor spaces as well as traditional gardens.

How to Choose a Tree Collar
Choosing the right tree collar isn’t just about visual appeal — it’s about matching size, material and functionality to your specific garden needs.
1. Measure Your Tree
2. Select Material Based on Environment

Timber: Best for shaded or mixed garden areas

Metal: Suited to exposed courtyards or contemporary landscapes

3. Consider Garden Style
Match the collar finish with existing elements:

Natural woods with leafy gardens

Cor‑ten steel with urban or industrial gardens

Polished concrete for minimalist landscapes
4. Think About Maintenance
-
Timber may need periodic sealing
-
Metal may develop patina or rust with time (for a lived‑in look)
-
Composite generally needs only basic cleaning
5. Installation Practicalities
-
Ensure level ground and firm base
-
For heavier stone collars, enlist help for safe placement
In simple terms, proportion, durability and style should guide your choice.
