Sedgehammer is one of the most gentle- to- turf products around. It has proven to be safe to most commonly used grasses of North America and has been successfully used for many years. Your grass should be well established with a good root system prior to application.
However Sedgehammer cannot be used in vegetable gardens or in or around annual plant beds. It can be used in landscapes around established woody ornamentals as a directed spray on the sedge. Avoid contact of Sedgehammer with the leaves or plant parts of desirable plants.
