Per the product label: During the season of establishment, GrazonNext HL should be applied only after perennial grasses are well established (have developed a good secondary root system and show good vigor). Most perennial grasses are tolerant to GrazonNext HL at this stage of development.
According to the product label, it is advised that you wait until the next growing season to plant in or seed an area after treating with GrazonNext HL Herbicide.
