Late-summer evenings settle slowly over Riverside, the light going long across the open meadow at Swan Pond while the streets above hold their warmth. Osshi Cleaning Services works the ordinary hours before that, mowing and trimming and carrying off the season's accumulation of leaf litter and stray growth from beds and borders. Grass is cut on a steady cycle so nothing ever has to come off in one hard scalping, and the edges along walks and drives are kept from creeping. Yard waste leaves with the crew instead of sitting bagged at the curb for a week. A property handled this way never looks rescued, only kept.
