With drought this past summer, Lisa Kortan, Urban Forester for the City of Yankton was asked about the care of Riverside Park lawn after Riverboat Days. She said that the park supervisor increased irrigation, aerated, and over-seeded the park with “park blend” grass seed that is sold locally. Photo was taken in late September after the August event.
