The term soil amendment refers to any material mixed into a soil and is the most important thing you can do to grow a healthy lawn. We recommend using either humus or our Triple Mix. With humus, rototill to a depth of 6 to 8 inches for 3 to 5 cubic yards per 1,000 sq ft of sod you’re planting. With our Triple Mix, simply lay 4 to 6 inches of compacted Triple Mix on top of your existing soil. We deliver both the humus and Triple Mix Monday through Saturday with a two-day notice, or you can pick up during our normal office hours. For more information on soil, check our Education page.
