For all the do-it-yourselfer gardeners out there, this post is a flat-out informational piece in hopes of having you learn from my mistake. And this particular one concerns the importance of using "paver edging" for your brick paver projects. Please do-as-I-say, not-as-I-do (did).
Alas, you can guess that the result was having the bricks at the edge eventually shift away from the center on all the edges, as pictured at left above, leading to an unattractive affront to my in ordnung sensibilities. Fortunately, the K-State Gardens had recently installed a paver walkway and I had carefully observed the construction and learned of the importance of paver edging. Paver edging is a simple commercial strip of plastic, "L"-shaped in cross section, that we lay down beneath and along the edges of our paver constructions to prevent just such migrations. Priced at approximately the weight of the plastic in gold, it should nonetheless be viewed as a necessity in your paver designs.
