Below is a table for the optimum mowing heights for turfgrass species in Indiana. The optimum mowing height is where the particular species will perform best, creating the thickest turf, and requiring the fewest inputs. Mowing above these heights will tend to create a less dense turf with coarser leaf blades, and potentially a puffy or scraggly appearance. Mowing significantly below this height will create a weak turf that will require more inputs like fertilizer, irrigation, and pesticides to control weeds, diseases, and insects. Can a turf species be maintained below the optimum mowing height? Yes, it can but be prepared to spend much more time, energy, and money to maintain that turf.
