Weedy Wednesday: Broomsedge

3 Comments

Though its name would imply it’s a sedge, broomsedge (Andropogon virginicus L.) is actually a clump-forming perennial grass.  It is most commonly recognized in the dormant stage as persistent tan clumps of dried leaves and stems.  Broomsedge is a weed of low-maintenance pastures, turfgrass, nursery crops, and other perennial crops.  It is usually found in open, sunny locations on low-fertility and drought-prone soils, particularly unmanaged meadows, roadsides, and waste areas.  It is found in California and throughout the eastern half of the United States, but not common in the northern New England States.

Reproduction of broomsedge is both vegetative and by seed.  Seedlings emerge in late spring or early summer.  Foliage of mature broomsedge plants is smooth or sparsely hairy and often has a whitish or bluish cast on the surface.  Clumps enlarge by spreading short rhizomes (underground stems).  In the fall, plants turn reddish tan and stems become stiff, persisting well into winter.  The hairy racemes of the spikelets are easily recognizable when the stiff stems blow in the wind.

Broomsedge is not a desirable species in pastures.  It has relatively little nutritional value for livestock and takes valuable nutrients, water, and space that could otherwise be used for desirable forage plants.  A heavy infestation of broomsedge is often considered an indicator of poor pasture.  It is a common belief that areas infested with broomsedge are low in soil fertility and have a low soil pH.

  1. I hate this stuff! Makes my pastures look like they are having a “bad hair” day! We are fortunate to not have a lot of it! Big problem is that most “hay makers” bale this in with their hay and then, when we feed their hay in the winter, we’re infested! Ugly stuff!

  2. We tested a little over a year ago and fertilized and limed, but last summer was heck on the pastures… drought! Our soils are extremely sandy/rocky, so we are lucky to have grass at all! Without the consistent rains we face drought weekly! Lots of weeds are cropping up this year as the forage grasses and legumes were stressed and overgrazed. It’s just going to take time and work to get them back into shape. Oh, and money! :(
