A tree guard is a square-based metal structure designed to protect the base of a tree. It is made of metal strips—thin strips of metal welded together to form a square grid. This grid creates a regular geometric pattern while providing the structure with strength and stability.
In the center of the tree guard is a circular hole, sized to accommodate the tree trunk. This hole allows the tree to grow freely, while the surrounding grid prevents people from stepping on the soil and protects the roots.
