The Pascack Brook threads the valley quietly, and the lawns that run down toward it hold moisture longer than the ones up on the rise — the same borough, two different growing conditions. Lawn-A-Mat of Pascack Valley reads that difference across Hillsdale yards, mowing to the right height, trimming and edging clean, then feeding and overseeding once September cools the nights. Fall is the honest season for turf here: less stress on the plant, more root below, the color coming back deep. Cleanups take the beds down and the leaves off before the ground hardens. Grass grown patiently in autumn is what carries a lawn through the next long summer.
