Answer: You can use a rake to rough the soil surface up a bit so the seeds can make good contact with the soil. If the spots are small, use a hand trowel. Then broadcast seeds over the soil, cover with a bit of compost or peat moss to help the seeds stay moist, and water well. Apply water once or twice a day to keep the seeds moist and they should sprout within a week. Raking might dislodge some existing grass plants, but the new seeds will take over the area and the existing grass should settle back down into the soil as soon as you water the area.
