Per the product label, Do not apply Triplet SF Selective Herbicide to newly seeded grasses until the new grass seed is well established which is usually after the 2nd mowing or atleast 30 days. If wanting to overseed after an application of Triplet SF Selective Herbicide, you will need to wait 3 to 4 weeks to apply Triplet SF for best results. Failure to observe all precautions may result in injury to turf and/or susceptible plants.Do not apply to newly seeded grasses until well established.
