A mowing strip using block pavers
Edging-
Keep edges to a minimum by making the lawn shape simple. Install a mowing strip (a hard surface level with the lawn) along the edges of the lawn so that the lawn mower can trim right over the edge. Any awkward tufts of grass and rough areas can be dealt with quickly using a nylon -line trimmer.
