Hand pulling younger plants (plants juts sprouted from seed) may offer some control, but once the tubers and nutlets have formed in the ground, pulling is not as effective. You may get the top of the plant, but many of the tubers and nutlets remain in the soil, ready to regrow. So if you want to physically remove the nutgrass, be sure to dig out the plant, foliage, tubers and all. If drainage is a problem (compacted poorly drained soils favor nutgrass growth), try to make necessary corrections to eliminate the problem.

For control in the open landscape beds, Roundup is your best bet, as it will move down into the tubers and nutlets for complete control. But, it generally will take repeated applications before getting nutgrass totally under control. Spray it, kill it, if it regrows, treat it again, and again, until control is complete. Remember that Roundup is non-selective and will kill what it is sprayed on. Use caution.

For the lawn, there?s a new product available that until recently, only licensed applicators could use. It?s called ?Manage?, and ?Manage? does an excellent job stopping nutgrass in its tracks in the turf. Spot treat the areas infected with nutgrass, not the entire yard. After the nutgrass disappears, keep watch for
any regrowth, which may require a second, possibly third application of ?Manage?.

Best wishes with your eradication project!
