Centipede pot serve as a pop lawn turf in warm , humid climates of the Gulf Coast . The pale green grass propagate by above - ground stem called stolens . Stoloniferous turf competes well with weeds , but it is not resistant to annual grass and perennial green goddess invasions . Typically , you apply pre - emergence weed killer to annual grass weeds when dogwoods are in bloom . Post - emerging herbicides work best when applied to perennial broadleaf weeds three hebdomad after green - up , accord to North Carolina State University Cooperative Extension ’s Centipede Grass Lawn Maintenance Calendar .
Crabgrass
Crabgrass educate in under - fertilized and frequently mowed lawn . The University Of Florida Institute of Food and Agriculture Sciences ' Crabgrass Biology and Management in Turf Thomas Nelson Page says most crabgrass specie originate as one-year grass weeds , yet blanket crabgrass and India crabgrass arise as short - survive perennials . Crabgrass reproduces by seed . The recognition characteristic vary by species , but most types of crabgrass possess a tufted or prostrate growth habit and all-encompassing leaf that conspicuously stand out from centipede grass .
Goosegrass
Goosegrass grow in compacted land and lawn with low fertility . The summer one-year reproduces by semen and germinates two to three weeks after crabgrass . Goosegrass also look like crabgrass , but the seed head are thick and the leaves are a darker shade of green than crabgrass , according to the University of Tennessee Extension ’s goosegrass profile . The extensive radical system and rosette - shaped base make the weed difficult to pull .
Prostrate Knotweed
Prostrate knotweed invades compacted soil and spots bust thin by foot traffic . The annual Mary Jane reproduces from ejaculate that germinate in leaping . The North Carolina State University TurfFiles page says prostrate knotweed seedling are frequently mistaken for forage , but prostrate knotweed ’s stringy stems radiate from a primal tap root and form a low growing mat of blue - green leaves and whitened flowers .
Pennywort
Pennywort , also known as dollarweed , takes root in wet sites . The perennial weed reproduces via seed , Tuber and above - land stems forebode rhizomes . The central petiole ( leafage stalk ) and the scalloped leaf make pennywort face like a small lily - launching pad , according to the Georgia Center for Urban Agriculture . The weed from time to time produces elongate spikes near the top of the stalk .
