Prepare the damaged area by removing all dead grass and 1" to 2" of soil 3/4" past the edge of the dead grass.
Water the area, then amend the soil by working in either compost, leaf mold or fine-milled peat moss to a depth of 3" to 5". Be sure to add enough to make up for the soil you removed.
Cut 2" by 2" by 1" plugs of grass from an area of healthy lawn and transplant them to the prepared area about 6" to 12" apart (4" to 6" works best for slower-growing grasses, 4" to 12" for St. Augustine grass).
Tamp them down with your foot, then keep them moist until you see them start to spread.
Regarding fertilization for transplanted areas, it's best to wait until your next regularly scheduled fertilization. Applying fertilizer during or shortly after the patch process can burn the roots of newly transplanted plugs.
