Lawn guide · Soil temperature

The number that runs your lawn.

Almost every important lawn decision in Oklahoma — when pre-emergent goes down, when Bermuda gets its first feeding, when the fall barrier matters — is answered by one number: the temperature of your soil a couple of inches down. Air temperature swings wildly here; soil temperature moves slowly, integrates the weather, and doesn't lie about what plants are actually experiencing.

The reading that matters most: 55°F and rising in spring is the crabgrass trigger. Our whole pre-emergent timing guide hangs on it.

≈55°F risingCrabgrass germination begins — spring pre-emergent must already be down and watered in

≈65°F risingBermuda begins waking; first real feeding window approaches

≈70°F fallingWinter annuals (henbit, Poa annua) germinate — the fall pre-emergent window

≈50°F fallingWarm-season growth ends; last fertilization should already be behind you

The Oklahoma Mesonet — the state's network of environmental monitoring stations — publishes live soil temperature maps. For our service area, the Norman and Oklahoma City stations bracket it well: current Oklahoma soil temperatures at mesonet.org.

Data is the Mesonet's — we link rather than republish. What we add is knowing what the number means for your yard.

On the program, you never watch this number — we do. Applications are timed to measured soil temperature for Moore, South OKC, and Norman, which is why the barrier goes down when it works, not when a route sheet says.

Let the soil thermometer be our job.
