Soil and pH Guide

Clay, compaction, organic matter and pH explained, with simple ways to test and improve the soil under your lawn.

Everything a lawn does begins in the soil. In Middle Tennessee, much of that soil is clay, which holds nutrients well but drains slowly and compacts easily. Soil also varies in organic matter, in pH and in how much air and water it can hold. Lawns on builder fill are often worst off, with hard, thin, low-organic ground. Improving soil is slow work, but it pays back in every season.

A soil test shows pH and nutrient levels and takes the guesswork out of fertilizer and lime. Core aeration relieves compaction, compost topdressing adds organic matter and correct mowing and watering build roots that improve soil structure over time. Avoid heavy traffic on wet clay. With a few seasons of the right practices, even stubborn soil can become a better home for grass, and treatments work better because the soil can use them.
