The act of compacting soil in a lawn using a roller aims to address uneven surfaces and improve seed-to-soil contact. An example scenario involves using a lawn roller after seeding or to address minor frost heaving that may occur during winter months.
Soil compaction, achieved through this process, can create a smoother surface that is easier to mow and aesthetically pleasing. Historically, rolling was used more frequently, but modern lawn care often emphasizes alternative methods to avoid excessive compaction, which can impede root growth and water infiltration.
