The first mow of April is a kind of ceremony in East Windsor. Along One Mile Road the ground softens, the forsythia goes off like a flare, and the grass finally asks for it. Jose Carpintero Landscaping opens the year right there — clearing winter's litter out of the beds, cutting high on the first pass, trimming and edging until the yard has its outline back. From then on it is steady work through the growing months, mowing on a week that holds and keeping the borders sharp against walks and driveways. There is a particular satisfaction in the smell coming off that first cut, and in a lawn that looks like someone is paying attention.
