Why does grass send out runners across concrete when there is soil immediately adjacent to the plant?

Asked by rojo (24179points) June 10th, 2016

Thinking of St. Augustine grass mainly since that is what is in most of the yards around me.
Is it something as simple as that is the way the runner was facing when it grew? Does the plant have a vested interest in seeking out new lands if what it is growing in is substandard? Does the increased heat given off by concrete draw the plant in that direction?
