Life Cycle – The summer annual large crabgrass is a member of the grass family. It is one of the most problematic lawn weeds. Crabgrass reproduces via seeds and has a prodigious habit of tillering or branching. A single plant can produce between 150 and 700 tillers and 150,000 seeds.
Crabgrass plants are exceptionally tolerant of mowing height. At mowing heights as low as 1/2 inch, plants can produce seeds. After being expelled from plants, crabgrass seeds remain dormant for a brief period. Soil temperature is related to seed germination. When the surface soil temperature reaches 55 degrees Fahrenheit for four or five days in a row, crabgrass begins to germinate.
The optimal time for seed germination is between early spring and late summer. The growth of crabgrass continues until midsummer, when the days become shorter. Slowing in growth, plants enter their reproductive phase. The plants produce purple seed heads until frost kills them.
