There is a half hour just after sunrise near Expo Park when the dew is still down and a mower leaves a dark track behind it you can read like handwriting. Top Grass Maintenance Care starts its days in that window, working the lawns on the streets off Exposition Avenue, cutting before the heat gets serious. Aurora grass grows in bursts — a soaking week in May, then weeks of hard blue sky — so the schedule bends to the lawn rather than the calendar. Every visit ends the same way: trimmed around the trees and the fence line, edges cut clean, walks blown off. By eight the dew has burned away and the yard looks like nobody ever touched it, which is exactly right.
