- Description
-
Carpetweed is a prostrate, flowering, summer annual weed that spreads rapidly to create a dense mat of foliage resembling a carpet. It can be found growing in sunny disturbed areas including tilled gardens, newly planted lawns, and along roadsides. It is typically found in dry and sandy soils, but can also be found in moist soil. It will germinate in late spring in warm soil, spreading rapidly. Small, 1/4 inch flowers appear in mid-summer and continue through the early fall.
Carpetweed needs full sun, moist to dry conditions, and sandy soil. It does tolerate partial shade and other soil types. Open disturbed sites are preferred because it is not competitive with other vegetation and does not do well when shaded by taller plants.
It spreads from a sparsely branched central taproot, creating a 5 inch high, often circular, mat. This plant spreads by reseeding itself, and often forms colonies. As it spreads, it can quickly climb over nearby plants and obstacles.
It is easy to remove this weed by either pulling or hoeing. It is important to remove it before it blooms in order to prevent the spread of unwanted seed.
Insects, Diseases and Other Plant Problems:
No known diseases or insect pests. This weed spreads quickly.
