You have to prepare the ground first before laying the sod for optimal growth. Remove the stones and debris. Use a tiller to till the area. The tilling will break the hard soil loose. Now use a rake to level the ground. If you need topsoil, use a rake to spread it over evenly.
Lay a layer of fertilizer over the topsoil to provide ideal conditions for the sod to grow. Moisten the soil lightly without making it soggy with a garden hose pipe.
Lay the sod:
Now that the ground is prepared, lay the sod. Start with the edges, moving towards the center. The edges tend to dry quickly so it is better to lay large pieces of grass there. Lay the pieces of sod together in a way that there are no gaps between them and the entire ground is covered. Join the seams together to make a seamless lawn.
Water the sod thirty minutes after laying it down. Water daily for two weeks after installation to provide ideal conditions for growth. A sprinkler helps in keeping the sod moist without draining it fully.
