Down where the Westfield River meets the Connecticut, Agawam's ground lies flat, sandy and generous — land that grew tobacco long before it grew lawns. Stellato Brothers Landscaping works it through the warm months, mowing, trimming and edging from Feeding Hills out toward the Provin Mountain ridge, where the trap rock catches the last orange light. July here is humid and fast-growing, and a lawn cut clean on a Thursday will be asking again by Monday. Cleanups in spring and fall reset a whole property — beds defined, borders sharp, the yard suddenly looking twice its size. A straight edge along an Agawam sidewalk in the evening is a small thing done right.
