Question
I am trying to find a source for concrete curved tree rings. These are usually about 2-3 feet long and you just place them together to make a ring around your tree. Usually you need about 5 or 7 pieces to make a ring. The problem I'm having is that all the ones I find have the bump on the inside shorter edge of the curve. I need ones that have the mow strip part on the inside part and the 'bump' on the longer outside edge. The reason for this is that I actually want to make sort of a zig-zag design around my trees instead of just a plain circle around my trees. I hope someone can direct me to a supplier of these. I'm in Alberta, Canada and I would like to find someone here in Canada but anywhere in the U.S. would be ok too for a supplier. Thank you very much.

Answer
For commercial applications, there is a supplier I've used before:  Quickcrete

http://www.quickcrete.com/treegrates.html

If you are in Canada, its quite a distance from these guys, as they are in So. California.

If I were you, I'd do a google search with the parameters: "Concrete Tree Grate" & maybe add "Canada", too. See what comes up.

There are lots of METAL products too, like Neenah (www.nfco.com), or Ironsmith (ironsmith.biz) - they may also carry a concrete grates or know someone who does.  ~M
