Type of Weed: Grassy Weed
Goosegrass is a common Texas summer annual grassy weed that is sometimes referred to as silver crabgrass or wiregrass.
This clump-forming weed is often found in parts of lawns with compacted soil, high-traffic areas, and thinner sports turfs. It grows prostrate in lawns that have a close mowing habit but can grow upright in areas where it’s left undisturbed.
It’s known for its white to silver coloring near its base, which helps to distinguish this from crabgrass and other grassy weeds. Goosegrass germinates in late spring and produces seeds from summer to early fall.
How to Identify
Stems and leaves are white to silver at the base, but then continue on as green in color. Sheaths are flat, split with overlapping margins, and are hairy at the top and edges. The ligule is membranous with a collar like appearance that have hairs on the back and the edges. Auricles, stolons, and rhizomes are all absent from this weed.
Goosegrass produces a 3 to 7 spiked seedhead at the top of the stem. Seeds form in a zipper like appearance on the spikes and release during summer to early fall. This tough weed dies off at the first frost, but seeds can stay viable in the soil for years to come.
Cultural Control: Avoid mowing your lawn too close as this weed thrives in thin, short turf. Routine aeration of your lawn will break up any compacted areas in your soil and work to deter new goosegrass from residing.
Mechanical Control: For younger goosegrass, or smaller infestations throughout the lawn, hand pulling or digging are good options. Make sure to dig up the entire weed and root system and dispose of properly. Digging up larger weeds can be useful, as long as they have not produced a seedhead and are setting seed.
Chemical Control: This weed is best controlled through the use of a selective pre-emergent grassy weed herbicide. Apply in late fall and again in early spring before the seeds have a chance to germinate. Apply a selective post emergent herbicide in early summer and throughout the growing season to help deter any future growth.
