North of Union Avenue the streets tilt uphill toward the Watchung ridge, and mowing them in May means working a slope with a good bit of respect. Fratelli Landscaping handles those yards: terraced strips of lawn, tight side yards, retaining walls that need trimming right up to the stone. May is the month everything grows faster than it can be cut, so the visits stay close together. Beds get mulched, edges get recut, and the whole slope reads clean from the sidewalk below. Bound Brook's hill blocks reward the extra pass.
