Sedgehammer is great for the nutsedge, but it is not recommended to be used on a brand new lawn. The real question would be how "new" is your lawn? Sedgehammer should only be used once your "new" grass is established, usually after 2-3 months so the roots have time to really take root. If this is the case and your lawn is established, then SedgeHammer would be great to use. It is recommended that you use a surfactant with the SedgeHammer to help it stick to the nutsedge and be more effective. We recommend Dynamic to use with the Sedgehammer.
