Behind the houses off Easton Avenue there are deep little back gardens you would never guess at from the sidewalk, and by late June they fill with fireflies around half past eight. Oliva Landscaping LLC looks after those hidden yards with mowing, edging, trimming, weeding, mulch and hedge work. A back lawn is where people actually live in summer, so the far corners and the fence line get the same attention as the front. Autumn brings leaf cleanup and the last cut of the year, and then the yard rests. The work spans New Brunswick, Highland Park, Somerset and North Brunswick.
