Ground in Trenton changes underfoot as you cross town, heavier on the piedmont side where the rock comes up, sandier where the land tips toward the coastal plain, and grass answers accordingly. Green Lawn Fertilizing reads a lawn that way, feeding it on a schedule the season can use, treating the thin patches, overseeding where a summer has worn the turf down to bare soil. Early morning is the honest hour for this work, when dew still holds a footprint and you can see exactly where a lawn is strong and where it is struggling. Weeds get handled before they set seed; color comes back not in a burst but in that slow deepening you notice a few weeks later from the front step. A green lawn in a river city is a matter of attention paid a little at a time.
