What is sprigging?

Sprigs are 3- to 6-inch sections of the horizontal stems (below-ground rhizomes or above-ground stolons) of creeping grasses. Sprigging is the act of planting the sprigs to start a lawn or to patch bare spots. In sprigging, cut the creeping stems into sections so that two or three nodes are present on each, and then plant them in shallow furrows so the nodes and roots are covered with soil, but the foliage remains uncovered.
