Spring on this stretch of Long Island arrives in a hurry — one warm week in April and every lawn in Coram is a shade greener than it was on Friday. Perfect Lawn Care meets it with the first cuts of the year, the cleanup that pulls winter's litter out of the beds, and the edging that hands a front yard its outline back. Street after street off Middle Country Road, the work is the same and so is the standard: a straight cut, a tight trim around the mailbox and the walk, clippings swept off the sidewalk. By August, when the air goes thick and the afternoons stack up with heat, the mowing keeps its rhythm anyway. Lawn care and seasonal cleanups throughout Coram, Gordon Heights, Selden and the nearby Brookhaven area.
