If you live in Bellville, Texas, then you know St. Augustinegrass! And… You have likely seen those pesky looking runners that look like weeds. Let not your heart be troubled, this is the sign of a growing lawn.
Although this may be a bit unsightly, this is not a huge problem and may in fact be a blessing.
If your lawn has dead patches or bald patches, these runners, called stolons, can help your lawn heal. Stolons can grow into the bald area and begin to build up the lawn in that area.
If your lawn is otherwise healthy, then you may want to just get rid of these unsightly things. Here is what Randy Lemmon, of the Garden Line in Houston had to say about the runners:

The commenter asked Randy Lemmon if anything could be done about the stolons other than yanking them up off the ground. The GardenMan’s cure was helpful.
First: Step on the rooted end of the stolon and yank till it breaks.
Second: To cure the problem, use core aeration!
Third: Treat with a soil amendment such as expanded shale, compost, gypsum, or Azomite.
