Learning about a youth’s experience, whether it’s your child or someone else’s, requires knowing how to communicate with that child.

Yes, Turfgass Cultivar Selection Matters!
July 15, 2025 | Written by: John Emerson, Turfgrass Nutrient Management Agent, Amy Shober, Nutrient Management and Environmental Quality Specialist and Erik Ervin, Turfgrass and Horticultural SystemsThere are several items to consider when establishing or renovating a lawn. Of course, water, light, soil nutrient levels, and temperature are essential, but one could easily argue that cultivar (cultivated variety) selection may be the most critical step in the long-term success and persistence of a lawn. Proper cultivar selection ensures that a particular turfgrass is best adapted to local conditions and will meet the turfgrass manager's use and maintenance expectations. Newer improved cultivars will establish quicker and form a denser turf to outcompete weeds. They require less supplemental irrigation, demand fewer fertilizer and pesticide applications, and maintain a more uniform turf stand throughout the growing season. These advantages ultimately translate into a significant reduction of inputs while still maintaining an excellent stand of turf.
