The active ingredient in Sedgehammer can remain in the soil for a long time. Since the manufacturer recommends waiting at least 3 years before planting vegetables in an area treated with Sedgehammer Herbicide, we recommend waiting at least this long before allowing animals to graze in an area treated with this herbicide.
When applying SedgeHammer Herbicide near edible trees be sure to apply it outside of the drip line. According to the manufacturer, this product remains in the soil for up to 3 years so the manufacturer recommends that you not plant anything edible in an area where SedgeHammer has been applied for at least 3 years.

Your desirable turfgrass is likely under a lot of extra stress due to the summer heat right now, so it would be better to wait the 2 weeks for the Tenacity application to work before applying another herbicide for the same target weeds.

SedgeHammer Herbicide can be applied 4 weeks after seeding.
