The seller should know this. Now to install the topsoil there is a formula. The formula for this is 12 cubic yards for sq. Now the top soil is sold in cubic yards. The minimum order is probably going to be at least 3 cubic yards. Just something to ponder if you are doing it yourself. Now the above is just our recommendation. Grading means leveling the lawn area to remove any low spots while sloping the lawn gently away from buildings and driveways. Apply the topsoil in an even 4- to 6-inch layer and then till it into the loosened subsoil.
This gives the grass a deeper rooting zone, while the more gradual change to the native subsoil allows water to drain and soak more deeply into the ground. If the lawn has low spots, fill them in with topsoil before adding the regular 4- to 6-inch layer on top so the entire lawn has a level, gentle slope.
After applying the topsoil, rake to grade the lawn again so it is level and ready for seeding. Your garden soil may need the boost of additional organic matter, which you can provide by mixing it with a 1- to 3-inch layer of compost. Clay topsoil is heavy and can impede drainage, while sandy topsoil drains too quickly and doesn't hold nutrients well.
If you have a lot of dirt clods, spread them out evenly because they will melt when you water. Apply 8 pounds per square feet of fertilizer and lightly rake it into the soil. Pick the best place to start unrolling the sod that minimizes the amount you might have to carry.
For example, if you will be sodding your entire lawn, start in the back and work to the front. If you are sodding part of your lawn, start in the front and work to the back until you run out of sod. Start by unrolling the sod to make a straight line.
For the next row, place a roll so it will unroll in the right direction a couple of inches away from the previous roll. Unroll it and slide the sod together. Do not overlap or leave gaps. Stagger the ends to avoid long seams. On steep hills lay the sod sideways across the hill rather than up and down.
Do not roll the sod because rolling will compact the soil and make new root growth difficult. Outside edges of sod that do not butt up to anything should have a little soil raked up to the exposed edge to keep the edge from drying out.
Begin watering when you can do so without making a muddy mess in the areas to be sodded. Using a spade or a powered cultivator if you have a large lawn the top cm of soil needs to be turned over and loosened.
Make sure you break up any larger pieces as you go. Any weeds need to be removed from the area, unless you want them interfering with your new lawn. This can just be done by hand, or a contact weed killer can be used. Avoid residual weed killers as these take some time to flush out the system so will affect your turf. Ideally you should just physically remove the weeds including the root, so they won't grow back or interfere with the new lawn. If the root is still present they may spring back up again in the new turf.
Make sure any large stones or debris are removed and the area is clear.
