GT Thorn Guard – Robust Tree Protection from Grazing Animals, Exclusive to Green-tech.
Protect your valuable trees from damage caused by grazing animals with the GT Thorn Guard, the ultimate solution for safeguarding both newly planted saplings and mature veteran trees. Grazing animals such as cattle, deer, sheep, and other livestock can inflict significant harm in a short period, often damaging tree bark and stems, which can stunt growth or kill young trees. The GT Thorn Guard provides instant, robust protection by surrounding the tree trunk with a tough, galvanised steel barrier equipped with protective spikes designed to deter even the largest grazers.

Crafted from heavy-duty galvanised steel, the guard is engineered to last in all weather conditions, ensuring your trees have the best chance to establish and flourish. Simple to assemble and install, the GT Thorn Guard is supplied as a flat grid that rolls into a cylindrical form fitting snugly around the tree. Its design promotes airflow and growth while preventing animals from reaching the vulnerable trunk.
