Foxtail is a spikelet cluster of annual grass that can quickly overtake your flowers or vegetables.

 Foxtail Grass

The Foxtail Setaria species consists of five weeds that cause massive obstructions of agriculture and land management. The species contains the giant, green, yellow, knotroot and bristly foxtail.

The grass gets its name from the bushy bristle on top of the stem. This bristle can grow to 6 inches in some species. When in a lawn, the grass appears to be a clump of crabgrass; only smaller.


Foxtail leaf blades are 4 to 15 inches long and have a spiral twist. The grass can grow up to three feet tall when left on its own.


Depending on the variety of Foxtail, the grass may flower anytime from June through December. The plant reproduces by the bristly seeds on its head.


Growing Conditions


Foxtail grows in sunny conditions – and very rapidly! Look for these plants in roadsides, ditch banks, pastures, cropland, orchards, vineyards, gardens, lawns and many other areas.




Foxtails have a shallow root system so pulling the grass out by hand can work when dealing with small numbers. Wear gloves to avoid the cuts from the bristly Foxtails.

Unfortunately, every time you turn your back more foxtail seems to appear. To combat the quick-growing nature, put down pre-emergent crabgrass preventer in the early spring.


Ortho Weed-B-Gon MAX Plus Crabgrass Control can treat Foxtail infestations.
