Infestation of Nutt Grass in my lawn. Tony - Coopers Plains
A: Nut grass in lawns may be controlled by spraying it with Sempra (Halosulfuron).
This product is effective against the family of grasses classed as ‘sedges’, and Nut Grass is a sedge. (As an aside - one peculiarity of sedges is that they have triangular stems).
Sempra will not kill off your lawn grass. Please keep in mind that you need to be persistent and several repeated sprays will be required to eventually eliminate the Nut Grass.
Sempra will kill off the nut grass it comes in contact with and ONLY the first ‘nut’ that the grass is growing from. Nuts further down the line on the runners will sprout…spray this out; and then more nuts still further along the runners will also sprout up. Spray this as well, and keep going until no more nut grass appears.
It can, at times, take four or five or even six sprays to eventually get rid of it all.
Who said gardening was easy?
