Crabgrass – the bad and ugly weed!


Crabgrass can invade a lawn and landsca9ping, potentially taking over

areas where grass or plants should be growing.  This grassy weed has

a lifecycle that only lasts one full year.  Being a summer annual, means that crabgrass likes to germinate in the spring, mature in the summer months, produce seeds, and die when the first hard frost hits our area. 


 Crabgrass is often a problematic lawn weed in lawns where it   wasn’t planted.  Crabgrass spreads by seeds in bunch formations and   has a light yellowish-green appearance, setting this grassy weed apart   from the desired type of grass in your lawn. A key feature   for identification of crabgrass is the white ligule (by the folded leaf   blade) and spiny looking hairs. 



When soil temperatures reach 55 to 60 degrees Fahrenheit, at a depth of 2 inches for a few days in a row, is when most crabgrass seeds begin to germinate.  Areas where Crabgrass can first be seen are along driveway edges, sidewalk edges, curb strips and lawn hardpans.  These areas capture heat from the sun and will increase soil temperatures rapidly allowing optimal conditions for seed germination.
