Help sourcing limestone planter block in St. Louis, MO
I was wondering if anyone in Missouri (St. Louis area) could recommend a good, inexpensive source for cut limestone blocks? I am not sure if I am even calling them by the correct name but I saved an article from This Old House from several years ago that refers to them as 'limestone planter block'. Basically I am looking for limestone blocks to dry stack for a 2' garden wall. I attached a picture of what i am referring to, though I don't even need them to be as large as in the picture. Any thoughts would be appreciated.
