Speedzone should only be applied to listed, established turfgrasses as directed only avoid applications to groundcover. You can find selective post emergent herbicides here for grassy weeds that are young and actively growing. You can spot treat very carefully or manually remove broadleaf weeds from the area. Applying pre-emergents prior to germination at appropriate timing in your area will offer great weed prevention in the future.
