What it looks like

Named for its bristly, cylindrical seedhead that looks like a little fox's tail. Giant foxtail has the largest, droopiest, hairiest head, green foxtail has a slim, upright, smoother head, and yellow foxtail falls in between with some hair at the base of the leaf.

Often mistaken for: Crabgrass or other summer annual grasses

When it shows up in the Triangle

Shows up during the same summer flush as crabgrass, sprouting from seed once the weather warms up.

Where you’ll see it

Mainly a problem in thin, weak, or disturbed lawn areas rather than thick, healthy turf.

What you can do

  • Keep your lawn thick and healthy through proper mowing height and regular fertility
  • Minimize bare or disturbed soil where seeds can take hold
  • Overseed thin spots to crowd out germinating weeds
  • Pull small patches by hand before they set seed
