In May the alewives push up the ladder at Damariscotta Mills, the gulls lose their minds, and Nobleboro knows the season has actually begun. Little Enterprises gets going the same week: spring cleanup first, winter raked out of the lawns, and then the mowing settles into its steady turn through June. Trimming and edging give a yard its outline; mulch in the beds holds moisture through the dry stretch of August. Autumn brings the oaks down along the back roads, and those leaves come off the grass before rain can glue them into place. Ordinary work, done on time, which is most of what a good lawn actually is.
