Lay St. Augustine Palmetto sod in spring, when the soil is moist and warm, for best establishment. Wait until after last frost for easiest digging and installation.
Prepare the soil in the chosen site. Rake the site to even it out and remove rocks, trash and weeds. Mix 2 inches of topsoil and 1 inch of organic compost into the top 4 inches of natural soil. St. Augustine Palmetto sod establishes best with loose, moist and moderately fertile soil.
Unroll the first section of sod in a straight line on the edge of the site. Use a sharp spade or knife to cut the sod to fit the site, and save the extra sod.
Unroll another roll of sod next to the first roll. Start the second roll 6 inches beyond the end of the first roll to stagger the ends for better drainage. Follow this pattern for each additional roll. Lay a piece of plywood on the grass before you step or kneel on it to avoid damaging the new sod.
Unroll further sod, with ends staggered in a brick-like fashion, to cover the site. Cover the entire plot with lengths of sod in straight lines, then fill empty spaces with the extra sections of sod.
Roll the lawn once with the grass roller to press roots into the soil. Water the grass for 30 minutes to establish the planting.
