Trees are beautiful to have in your yard, but they can sure be a pain to mow around. Instead of fighting roots to get your grass cut, install one of our concrete tree rings instead! Tree rings are useful for a couple of reasons. First, they protect your mower from those pesky roots. Second, they protect your tree from the mower. And as an added bonus, they're decorative as well! Fill in your tree rings with one of our stunning decorative rocks for a tree with form and function.
