If you are here, you are trying to wave your magic wand to turn your non-yard into a flourishing lawn by laying down new sod. The good news is, it is much like waving a wand in that you will suddenly have something beautiful where you once had nothing. The bad news is, the magic wand is really more like manual labor. If you are laying down sod over your entire front yard, expect to commit a fair amount of time and effort to this project.
To be sure of your layout, use some rocks or a ground spray paint to lay out where the edges of the grass will be and where it will meet your flower beds. (Tip: Unless you are working along hardscape items such as paths and patios, it is a good idea to make wavy patterns with the edge where your grass meets your beds).
Unroll the sod so it lays flat on the ground. Sod usually comes in rectangles roughly 1' by a little more than 2' so it can get heavy if it has been recently watered. Be careful with the dry squares however, because they will tend to tear and crumble if you attempt to handle them by only one side (always use both hands, hold it like a baby).
Start your first piece on one corner of your target area and leave the sod so that it lays halfway outside your edge line. The reason for this is because you have to lay it down in a brick pattern, so that the lines will never line up like a tile floor. You need to make sure you stagger the edge lines. Once you have laid your first piece, lay the second next to it and so on until you have completed your first row. Then, this time starting with the edge of the sod flush with the edge of your area, lay them down across the second row.
When sides of sod squares meet one another, make sure you turn the exposed dirt inward and give it a good press, there should be a small amount of pressure between each of the squares to ensure no gaps will form.
When you have laid all of the sod down and it covers the whole area, take your edger tool and cut the sod to your planned edge lines. For more fine work, use your snips or your knife. You may then use the remaining pieces to fill any small areas you left uncovered to save whole sod pieces. If you are laying on hills with heavy slants, buy sod staples and nail them through the squares to keep them from sliding in the rain, or from your watering.
Water once or twice a day as needed to keep them saturated, if you see any pools of water, be sure you give watering a break.
Enjoy your beautiful, brand new lawn!
