You will have to remove that outer course of pavers on both sides.
To install the paver edging.
In order to put the proper edging down that gets spiked, you have to take out those two outer courses, so that you can put the edging down and put it in place. The bottom edge of the "L", which makes the edging, goes under the bricks, below the fill.Why would he have needed to remove the outer course of pavers in any case?
There are two forms of that edging. One that you spike on the outside, the other has an edge that goes under the outer course of paver's. It just depends on which type is available locally.So, you would remove pavers, to install paver edging that doesn't go under the pavers, but should be installed, and staked, alongside the pavers?
Sorry, I don't get it....
