Late August along Communipaw the evening cools slowly and the back gardens are at their loudest — tomatoes leaning on their stakes, a fig wrapped into one corner, grass that put on a week of growth in the heat. Perez Lawnmowers & Gardening Services works with that abundance rather than against it: mowing, trimming, weeding, keeping the garden beds shaped so the growing stays deliberate. Jersey City backyards do a great deal of living in a small footprint. The job is to keep them walkable and cut while the season runs hard. When it turns, everything gets cleared down and put to bed for the winter.
