Best nutsedge weed killer

Nutsedge, also called nut grass, is a tough summer weed that’s hard to get rid of. Even though it seems to die in winter, its strong roots stay alive underground. The most common type is yellow nutsedge, but there’s also purple nutsedge.

For every plant you see, there could be up to 18 more hiding underground roots, ready to grow next year. It’s a bright yellow-green color and looks like tall grass, but it grows much faster. After mowing, nutsedge quickly stands out by growing taller than your lawn.

To tackle nut grass, check out the 5 best nutsedge weed killer.

  • Yellow Nutsedge (Cyperus esculentus): One of the most common sedges in lawns.
  • Purple Nutsedge (Cyperus rotundus): Another sedge species that Sedgehammer can effectively control.

Multiple applications and potential resistance development should also be considered in long-term weed management strategies.

  • Broadleaf Weeds: Common broadleaf weeds targeted by tenacity include dandelion, clover, chickweed, henbit, ground ivy, and many others.
  • Grassy Weeds: Tenacity can control grassy weeds such as crabgrass, annual bluegrass, and more.
