Look west from Lincoln Park in April and the hills toward Montville and Towaco go that first uncertain green, a week or so ahead of the flats down by the river. That is the signal Andes Landscaping LLC waits on: time to rake winter out of the turf, cut back what browned over, and start the mowing season in earnest. Through the warm months the work is steady and unglamorous, even cuts and trimmed fence lines, mulch laid smooth, edges held sharp all the way through August. By October those same lawns are cleared of leaves so the grass can breathe into the cold. A borough of modest yards, each one worth the full hour it takes.
