Come the third weekend of October the old courthouse on the square is ringed with crowds for Gold Rush Days, and every lawn in town is under an inch of poplar and maple leaf. Dahlonega Landscaping LLC works the whole arc of that season — leaf removal and fall cleanups, mowing right through the last warm week, beds cut back and mulched before the cold. Color comes late and hard in these mountains, and then one north wind takes it all down at once. Clearing it properly, back to green grass and swept walkways, is among the more satisfying jobs of the year. The rest of the calendar the routine is mowing, trimming and edging, done on the day it was promised.
