Flower Bed With Trench Edging
Finish this type of trench lawn edging by covering the area with some type of mulch. A mulch layer helps keep weeds from sprouting in the uncovered soil and prevents soil erosion from the planting bed itself. If your trench area is shallow, you can run your lawn mower along the bed edge by dropping one wheel into the trench. This eliminates any need for string trimming the lawn edge.
