Aluminum Landscape Edging for Tree Rings

For residential tree rings, the 1/8" (3.2mm) CrispEdge or EZ-Edge is ideal — lightweight, flexible, and easy to curve. For commercial or high-traffic areas where greater rigidity is needed, the 3/16" SureEdge provides added strength while still accommodating smooth circular shapes around trees.

Aluminum edging flexes naturally into curves without tools. For tree rings, simply bend the section into your desired circle radius and stake it in place using the 45-degree stake angle method. Sure-loc's edging sections can also be cut on-site to achieve precise ring diameters, ensuring a clean, professional finish.

No. Aluminum does not rust or corrode, even in consistently moist soil conditions common around tree bases. Sure-loc aluminum edging is non-toxic, corrosion-resistant, and rated for marine environments — making it an excellent long-term choice where soil stays damp near irrigation, mulch, or rainfall.

For most residential tree rings, a 4-inch height aluminum edge installed with approximately 1–2 inches below grade provides stable, clean borders. In areas with steep slopes, sandy soils, or frost-prone climates, the 8-inch SureEdge model offers deeper anchoring to prevent shifting during ground movement or temperature changes.

Yes. Sure-loc's Anti-Frost Heave Technology uses stake pockets angled at 45 degrees, which prevents the edging from being pushed up by ground heaving during freeze-thaw cycles. This is particularly valuable for tree ring applications in northern climates, ensuring the edging stays flush and level year after year.

The required length equals the circumference of the ring: multiply the diameter (in feet) by 3.14. For example, a 6-foot diameter tree ring needs approximately 19 linear feet. Sure-loc edging ships in 8-foot and 16-foot sections, so you can cut to exact length on-site with no waste and seamless connections.
