Chapter 11 – Lawns: Grasses, Seeding, Sodding, and Care

The green carpet everyone wants.

Love it or hate it, the lawn is the largest “planting” in most landscapes. Chapter 11 provides a complete guide to lawn grasses, establishment methods, watering, mowing, fertilizing, and troubleshooting.

The first decision is grass type. Cool-season grasses (Kentucky bluegrass, fescue, ryegrass) thrive in northern states with cold winters. Warm-season grasses (Bermuda, zoysia, St. Augustine) take over in the South. The book includes a map of grass adaptation zones and a table comparing shade tolerance, traffic resistance, and maintenance needs.

You have two ways to start a lawn: seed or sod. Seeding is cheap ($0.10–$0.30 per square foot) but takes time and requires careful watering. Sod is instant ($0.50–$1.00 per square foot) but heavy to install. The authors recommend seeding for large areas and sod for small patches or erosion control.

Soil preparation is identical for both: remove existing vegetation (by solarization, smothering, or herbicide), till to 6 inches deep, add compost, rake smooth, and roll lightly. For seeding, spread half the seed in one direction, then half perpendicularly. For sod, stagger the seams like brickwork and water immediately.

Once your lawn is established, maintenance matters. The single biggest mistake people make is mowing too short. Set your mower height to 3–4 inches for cool-season grasses and 1.5–2 inches for warm-season. Taller grass shades out weeds and develops deeper roots. Never remove more than one‑third of the blade at a time.

Watering deeply but infrequently trains roots to go deep. One inch of water per week (including rain) is enough for most lawns. Water in the early morning to reduce evaporation and fungal disease. A tuna can placed on the lawn makes an excellent rain gauge.

Fertilize cool-season lawns in spring and fall; warm-season lawns in late spring and summer. Use a slow-release nitrogen fertilizer. The book warns against “weed and feed” products unless you have a severe weed problem—they apply herbicide to areas that don’t need it.

Lawn truth: A perfect lawn is a myth. Aim for healthy and green, not golf-course perfect.
