Hands potting a fern into fresh compost

Late summer decides next spring. Lawns that enter fall with deep roots and honest height green up weeks earlier — while scalped, thirsty turf spends autumn just recovering.

Raise the blade

Hold mowing height at 8–10 cm through heat. Taller blades shade the soil, hold morning dew longer and outcompete crabgrass without a single extra product.

“Water like it rains: an inch at once, once a week. Daily sprinkles train roots to live at the surface.”

The August checklist

  • Water deeply one morning a week; skip days after real rain.
  • Leave clippings — they return a free quarter of the lawn's nitrogen.
  • Spot-seed worn patches now so seedlings root before frost.
  • Book fall aeration and overseeding before the September rush.

Do this through August and September's overseeding lands on turf that is ready to receive it — which is exactly when our crews like to arrive.
