Abstract: A method of and an apparatus for forming a containment volume into which concrete, or another suitable landscape border material, may be added to form a landscape border involves positioning first and second elongate members such that the distance between them is substantially the same as the desired width of the landscape border. At least one connecting member configured to engageably interconnect with each of the first and second elongate members is positioned between the first and second elongate members to secure them at the desired landscape border width and thereby form a containment volume having a structural integrity that is sufficient to withstand the lateral forces imposed on the containment volume during addition of the concrete, or other landscape border material, into the containment volume.
