Sunnyside Gardens shares its backyards, which means a lawn there belongs to a whole row of neighbors at once. Gardening|Js Landscaping Pro Corp. tends common ground like that — mowing, edging, hedge and shrub trimming, planting and bed care, seasonal cleanups — then switches to plows, shovels and salt when the borough goes white. Under the el in Woodside the light falls in stripes all day and grass grows in patches, so the work is coaxing an even green out of an uneven place. Winter simplifies things: clear the walk, clear the drive, salt the corner where everybody cuts across. Two very different jobs, one plain aim — a property that stays usable all year.
