Which feature helps mowing and restrict grass encroachment between lawn and ornamental plantings?

• A. Letting grass encroach into the beds
• B. Using soft, flexible edging that can bend easily
• C. Installation of structural edging material between lawn and ornamental plantings
• D. Clearing edges to create flat, seamless transitions

Answer: (C)

A rigid, structural edging material placed between the lawn and ornamental plantings provides the key boundary that keeps turf away from the beds while making mowing easier. This solid barrier stops grass runners and roots from creeping into the mulch and bed soil, so the border stays clean and reduces the need for ongoing edging and weeding. It also gives a predictable, stable edge for the mower to follow, preventing the blade from crossing into the planted area and ensuring a neat, uniform transition. In contrast, soft edging or letting the grass encroach offers little resistance to spread, can bend or shift under mowing, and makes it harder to maintain a crisp edge. Clearing edges for a seamless transition removes the barrier that keeps turf out, which can lead to more encroachment over time.
