The first mow of the year around the Ossining and Briarcliff line usually happens on a cool bright afternoon in April, and the smell of it carries three houses down the block. Everything is soft then — the ground gives, the grass is tender, and the whole yard is waiting to be told what shape it's in. MJ Landscaping & Masonry Inc. starts the season there and stays with it, mowing weekly, trimming and edging the borders, mulching the beds and clearing the yard when autumn finishes up. The pleasure of the job is watching a property come back from bare and stay looking cared for all the way to November. Ossining and the towns along its border are the regular route.
