October nights around here run cold enough to silver a lawn by morning, and that is exactly when turf wants tending. Greener Lawns Landscaping Company works the grass itself — cut and edged, corners trimmed, thin spots seeded, fallen leaves lifted off before they smother whatever is underneath. Sandhill cranes pass over Calumet in loose noisy strings this time of year, high and headed somewhere warmer, while the ground stays and has to be cared for. Come the thaw the clearing starts again, winter's litter pulled out and the first cut setting the tone for everything after. Greener is less a boast than a direction to keep walking in.
