Farmington Hills keeps a forest inside itself — the wooded acres of Heritage Park, and after them a hundred neighborhoods still standing under oaks that were here first. Natural Way Lawn and Tree Service works in that shade, mowing turf that gets only part of a day's sun, trimming around trunks and root flare, feeding lawns that compete with big roots for everything, and clearing the litter a canopy drops all season long. Grass under mature trees is a different problem than grass in the open, and it asks for a lighter, more patient hand. When it comes in thick beneath a broad old maple, that is a genuinely satisfying thing to look at. This city earned its trees, and the ground below them deserves the same care.
