A foliar iron spray darkens the lawn's color without forcing the leaf growth a nitrogen feeding would, which is exactly what summer-stressed turf needs. Iron is taken up directly through the leaves, so results show in days rather than weeks. Shallow soil temperatures are in the action band at 102°F at 2 inches at the Monahans 6 ENE sensor, 29 miles from your location.

Pest Watch
White grubs are the larvae of Japanese beetles, June bugs, and similar species, and they feed on grass roots through summer. Catching the first generation in early summer, before significant root damage, makes preventive insecticide much more effective than rescue treatments. Shallow soil temperatures are in the action band at 102°F at 2 inches at the Monahans 6 ENE sensor, 29 miles from your location.

Pest Watch
Fall armyworms can strip a healthy lawn down to brown stems in days once the caterpillars are large enough to feed actively. Migration patterns make outbreaks unpredictable; watching for the first signs in late summer means you can treat before the damage is done. Shallow soil temperatures are in the action band at 102°F at 2 inches at the Monahans 6 ENE sensor, 29 miles from your location.

Soil temperature by depth
Zone 8B
November 12
1,970 ft
Warm-season only
Not suited for cool-season grass. Consider warm-season varieties. As of August 20, the 2-inch soil temperature is running 11°F above the 10-year normal for this date. With an average first frost of November 12 and an elevation of 1,970 feet, your fall seeding window timing is shaped by both soil temperature trends and frost risk. Zone 8b soils rarely stay below the 55°F pre-emergent threshold for long, so monitoring for early crabgrass flush is critical. Readings come from the Monahans 6 ENE NOAA research-grade station, 29 mi away.
For established lawns and gardens, the 4 inch soil temperature is a more useful reading than the surface. This 4-inch root-zone depth changes more slowly than the 2-inch surface layer, so it is a steadier signal for timing fertilizer, aeration, and weed control. The depths your nearest station reports are shown above; stations in the federal network typically report 2, 4, 8, 20, and 40 inches, while modeled estimates for areas far from a station cover fewer depths.
This week’s watering for Odessa, TX
Water 1.5 inches, or let the lawn go dormant
| Weekly target | 1.5 in | at 102°F soil, for cool-season grass |
|---|---|---|
| Expected rain | 0 in | over the next 7 days |
| You supply | 1.5 in | in 2 deep sessions, watered 4-9 AM |
The weekly target includes rainfall, so irrigation only covers the deficit. Water deeply and infrequently rather than a little every day: shallow daily watering builds shallow roots and invites disease. Above 85°F, a cool-season lawn can also stay dormant on about 1/2 inch every 2-3 weeks, just enough to keep the crowns alive. Rainfall is a modeled forecast estimate for this location.

Soil moisture near Odessa, TX
Normal for this time of year
The 2-inch soil is at 2% volumetric water content, around the 34th percentile of this station’s own history for this time of year.
Measured at 2 inches by a NOAA USCRN station, as of August 17.
The wetter-or-drier comparison uses this station’s own readings within about two weeks of today’s date, pooled across 5 years (155 readings). Frozen-soil days are left out. Baseline last computed July 19.
Lawn disease risk
The 7-day forecast near Odessa, TX favors active disease pressure. These diseases are the ones to watch now. Based on a modeled weather estimate for this location.
| Disease | Risk | Why now |
|---|---|---|
| Brown patch (Rhizoctonia solani) | Favorable | 7 of the next 7 nights stay above 68°F with hot days; worse with excess nitrogen. Water only 4-8 AM so blades dry by evening, ease off quick-release nitrogen, and improve airflow. |
| Pythium blight (Pythium spp.) | Favorable | 7 of the next 7 nights stay above 65°F with hot days; worse with excess nitrogen. Water early morning to limit leaf wetness, hold nitrogen to 0.25 lb/1,000 sq ft, and fix drainage in low spots. The fastest killer, 2-3 days. |

Growing degree days near Odessa, TX
Michigan State ground-truthed these models in the Great Lakes region and does not recommend them for the mid-south transition zone or the South. Outside the Upper Midwest and Northeast, read them as a guide and confirm against local extension guidance.
Growing degree days measure the heat a lawn has accumulated this year: each day adds the amount its average temperature runs above 50°F, the point where cool-season growth and most pests get going. Turf managers use the running total to time crabgrass pre-emergent, annual bluegrass seedhead suppression, and grub control. Pairing it with the current soil temperature shows both the season's heat so far and what the ground is doing right now. Measured at the NOAA station Monahans 6 ENE.

Weather context
Right now the ground near Odessa is about normal for this time of year: the soil at 2 inches holds 2% water, around the 34th percentile of this station's own history for the date. The reading is measured at the station, not modeled.
For warm-season grasses, yes. The 2-inch soil temperature near Odessa, TX is currently 101.7°F, measured in the ground at the Monahans 6 ENE monitoring station (28.6 mi away). That is at or above the 65°F threshold where Bermuda and zoysia establish, and above the 50–65°F cool-season band, so hold cool-season seeding until soil cools back through 65°F.
The soil at 2 inches near Odessa, TX is at 2% volumetric water content, around the 34th percentile of this station's own history for this time of year, so the ground is about normal for this date. This is a direct ground measurement from 337 active USDA and NOAA in-ground monitoring stations, not a forecast or a model.
Soil temperature outside the germination band is the most common cause. The 2-inch soil temperature near Odessa, TX is currently 101.7°F, measured in the ground at the Monahans 6 ENE monitoring station (28.6 mi away). Cool-season seed germinates at 50–65°F and warm-season seed at 65°F or higher; outside those bands seed sits dormant rather than sprouting. If the temperature is right, the usual culprits are seed buried too deep, topsoil that dried out during the sprout window, or a pre-emergent herbicide applied the same season, which blocks grass seed the same way it blocks weeds.
Cool-season grasses like fescue and bluegrass germinate best when soil at 2 inches stays between 50–65°F for several consecutive days. Warm-season grasses like Bermuda and Zoysia need soil temperatures of 65°F or higher before seeding. If you are seeding, a high-phosphorus starter fertilizer goes down in the same window; regular established-lawn fertilizer follows different timing.
Apply pre-emergent herbicide, the product sold at retail as crabgrass preventer, when soil at 2 inches reaches 55°F for several consecutive days. This is the threshold where crabgrass and other summer annual weeds begin germinating, and applying after that point reduces effectiveness significantly. Weed-and-feed products that include a pre-emergent follow the same window. The pre-emergent timing page for Odessa tracks this threshold against the current reading.
Odessa, TX is in USDA hardiness zone 8b. Cool-season grasses (tall fescue, Kentucky bluegrass, perennial ryegrass) are built for winters here and stay alive under frost and snow. Warm-season grasses risk winterkill in this zone: Bermuda and zoysia come through mild winters but thin or die back in hard ones.
Use 2 inches for germination decisions, since that is where seeds sit. Use the 4 inch soil temperature for established lawn and garden timing: it reads the root zone, changes more slowly than the surface, and is the depth most fertilizer, aeration, and disease guidance references. The 8 inch reading shows deeper root-zone trend. The 20 and 40 inch readings track deep soil and frost depth where federal stations report them.
Soil changes temperature much more slowly than air due to thermal mass. A warm afternoon does not mean the ground is warm. Soil temperature lags air temperature by days or weeks, making it a more reliable indicator of when biological processes like germination actually begin.
It is a direct ground measurement. The 2-inch soil temperature near Odessa, TX is currently 101.7°F, measured in the ground at the Monahans 6 ENE monitoring station (28.6 mi away). Soil Temps reads from 337 active USDA and NOAA in-ground monitoring stations, which report daily at depths from 2 to 40 inches.
Each window above is counted on its own base temperature and start date, which is why those numbers differ from the headline total. A target range means nothing without them.
