When should I Dethatch my centipede lawn?
Because centipede grass grows vigorously during the warm summer months, dethatch your lawn in late May or early June. During this partial removal process, centipede grass encounters a lot of stress, so the growing season allows it to recover rapidly before dormancy sets in.
Correspondingly, when should I winterize my centipede grass?
Raise the mower blades to 2 inches in late fall or early winter before the last frost, and mow centipedegrass at this height for its last mowing of the season.
