Commercial-grade aluminum stakes, 1/8″ thick, made to my specification. Extra tall, which gives you room to set a tag above groundcover or mulch instead of down inside it.
Dimensions: 10.5″ tall x 5/8″ wide
Material: 1/8″ aluminum
Mounting a tag to one
Outdoor-rated 1/2″ 3M VHB tape is what I use, and it holds well. In a bed that sees foot traffic, or anywhere a hose or a dog can catch a tag, add a screw or a rivet as well — tape alone will eventually let go of something that gets knocked repeatedly.
Limited availability.
Care and installation
Soap and water for the stake and the tag. If your ground is hard, water the spot the evening before and open a pilot hole first — the care and installation guide covers hard desert soil and caliche.
