Late August, and the big shade trees over Watervliet's older blocks turn every lawn into a puzzle of sun and shadow — thin grass beneath the canopy, thick growth wherever the light gets through. Tall Oaks Landscaping LLC reads that difference and cuts for it: mowing at a height the shaded turf can live with, trimming around trunks and surface roots without scarring bark, a clean edge at the walk, the beds under the drip line kept from going wild. Landscape work fills out the rest — plantings tended, borders defined, overgrowth taken back before it swallows a front step. Evening comes early under a canopy, and the yard cools while the street out front is still warm. A well-tended lawn under old trees is a small, steady kind of beauty.
