West of Jackson the frost lets go of the low ground first, and the flats along the Falling Waters Trail turn soft and dark weeks before the ridges do. That is when the season opens here — mud on the boots, the first cut still a few warm days away. Ultimate Dirt Services LLC keeps Jackson lawns mowed, trimmed and edged from that thaw all the way through the long green stretch of July. There are cleanups in spring to clear off what winter left, and again in fall, when the street trees give up everything in about a week. The work is plain and so is the proof: a yard that reads as cared for from the sidewalk, edges cut clean along the walk and the drive.
