Round Rock, TX Lawn Care — what actually works on this dirt

Bermuda fairways, blackland-clay-meets-sandy-loam soil, Stage 2 water restrictions year-round. Here's the no-fluff guide for the homeowner who wants a lawn that looks intentional without spending Saturdays guessing.

You have the same soil challenges your neighbor has. The difference is whether you're measuring it or guessing at it.

Round Rock's Stage 2 restrictions aren't a punishment — they actually align with what TAMU AgriLife recommends for Bermuda anyway (early-morning watering, twice-weekly deep soaks). The city is doing you an agronomic favor; lean into it.

Right now in Round Rock

  • Soil temp is climbing through 65°F — your warm-season grasses are waking. First mow of the season next 7-14 days.
  • Pre-emergent window for crabgrass closes when soil hits 70°F sustained. If you haven't put down prodiamine yet, this is the last call.
  • Bermuda greens up unevenly — don't panic-fertilize the brown patches yet. Wait until 80% green coverage before the first heavy nitrogen pass.
  • Watch dewpoint after May 10. Dollar spot pressure climbs fast in our humidity, especially on overwatered north-facing slopes.

A real Round Rock lawn, three buried probes, one experiment

The TurfPulse founder lives here. He buried three soil moisture probes in his Bermuda lawn, mapped them to his Rachio zones, and is documenting every irrigation decision from May 1 through Memorial Day weekend. The rule: "my sensors tell the controller when to water."

All the math is open. The gear list (with affiliate links) is public. The water bill receipts will be too. If you live in Round Rock and you want to see what your lawn could look like by August 1 if you stopped firing on a calendar — read the methodology page below.
