Can I use SedgeHammer to kill Bermuda weeds? And not burn my St. Augustine grass


SedgeHammer + Herbicide will not control bermuda but is safe to use on St Augustine and Bermuda for the weeds listed on the product label.   Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the St. Augustine as well.  In your situation it is recommended to spot treat the Bermuda with Round Up/other non selective herbicide and kill it directly, and then replant St. Augustine in those areas.   It can take multiple applications to eliminate it and best time is in the spring as it is starting to green up.
