Just past the northern edge of Manville the Millstone gives itself up to the Raritan, and the borough sits in the flat green bottomland the two rivers made. Mana on Earth Landscaping LLC takes its year from that ground: soft, fast-growing summers that want mowing and edging, then a hard clear winter that wants a plow blade before sunrise. Summer work is the pleasure of a lawn brought back to order — trimmed close around the posts, swept off the walk, done before anyone is out looking. Winter work is quieter and colder, a set of headlights moving down a side street so a driveway is open and salted when the coffee is still hot. Same streets, two very different kinds of care, and both of them leave a place better than they found it.
