To earn the Pretty Gardenribbon, a farmer must place flower bouquets on their farm. Unlike Architect or Baled Out ribbons the counter is not decreased when bouquets are removed so there is no need to have all bouquets placed in same time. Flower bouquets can be obtained by harvesting a perfect bunch of flowers planted by a farmer or from neighbors. If a farmer harvests a Perfect Bunch, he can either keep them (if he owns a Garden Shed) or may share them with his neighbors. If a farmer does not own a garden shed, they must rely on their neighbors sharing their perfect bunches.
When a farmer buys a Garden Shed from the market, they will receive 10 free bouquets, which will automatically earn them the white ribbon.
