Why gardeners reach for these:
● Protects tree trunks from strimmer and mower damage
● Rust-finish non-galvanised mild steel develops a natural patina over time
● Two sizes — 50cm or 70cm diameter— to suit different tree ages and trunk sizes
● Rust releases metal oxide which helps bind the soil, increasing nutrient absorption
● Simple to install around an existing tree
Product Description
A single pass with a strimmer or mower collision can do lasting damage to a tree's bark and trunk— and it's one of the most common, easily preventable causes of tree stress in gardens. Devonia's Metal Tree Protection Ring maintains lawn cutting at a safe distance while ageing into a natural rust patina.
Made from non-galvanised steel, the ring is left to weather naturally, developing a rust finish that blends into the garden rather than standing out. Choose the 50cm size for younger or smaller trees, or the 70cm for more established ones — both create a clear, physical boundary against strimmer and mower damage, robot lawnmowers included.
How to use:
Position the ring around the base of the tree, ensuring an even gap from the trunk.
