Carpetweed is a summer annual with a short taproot. Seeds lie dormant over the winter and sprouts slowly in the spring. Once it sprouts it grows rapidly in the summer heat.
Prefers fertile, dry, sandy or gravelly soil in lawns and landscapes along walkways. It is commonly found in shaded areas in the lawn and may be a problem in spring seedings of new lawns.
Can be hand pulled or use a broadleaf herbicide in early to midsummer.
Pre emergent herbicides applied in mid spring will prevent carpetweed from developing. Keep the lawn vigorous through a regular fertilization program and good mowing practices.
