A year in Alpharetta runs as four distinct assignments: wake the lawn up, hold it through the heat, catch the leaves, then keep the beds honest until it starts over. Unlimited Lawn Care takes all four — mowing and edging on a set rotation, string trimming, fertilization and weed control, aeration and overseeding, mulch, shrub trimming, leaf and seasonal cleanup. Old Milton Parkway traffic thins by mid-morning and the neighborhoods behind it go quiet enough to hear a mower three streets over. That sound on an ordinary Tuesday is the sound of a whole town being kept. Johns Creek, Roswell, Milton, Duluth and Cumming share the same calendar.
