When does pre-emergent application typically open in Westwego, LA?

Pre-emergent application typically opens in April to June for Westwego, LA, when 2-inch soil temperature reaches the 50–55°F threshold for several consecutive days. Apply earlier than that and the herbicide degrades before crabgrass germinates; apply later and weeds have already sprouted. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

What grass types grow best in Westwego, LA?

Westwego, LA is a transition zone where both cool-season and warm-season grasses are common. Warm-season grasses (Bermuda, Zoysia, St. Augustine, Centipede, Bahia) thrive once 2-inch soil sits above 65–70°F and go dormant brown over winter. Picking a grass family that matches the climate is the single biggest lawn-care decision; transition-zone homeowners often maintain blends and accept that neither family will look perfect year-round. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

When is the first fall frost typically expected in Westwego, LA?

In Westwego, LA, the first fall frost typically arrives around November 1. Soil temperature continues to drop through October and November, which closes the fall fertilizer window for warm-season grasses and opens the dormant-seeding window for cool-season grasses. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

How often is this schedule updated?

Recommendations recompute every 6 hours from Open-Meteo's ERA5-Land modeled soil-temperature estimates for Westwego. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

What soil temperature do warm-season grasses need to germinate?

Seeded warm-season grasses like Bermuda and Zoysia germinate best when 2-inch soil temperature stays at 65–70°F or higher for several consecutive days; below that range, seed sits dormant or rots. St. Augustine establishes from sod or plugs rather than seed, but takes hold in the same warm-soil window. The re-entry interval (REI) on any post-emergent products you apply during establishment is on the product label; respect it before letting pets or children back on treated areas. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

Where does the soil temperature data for Westwego come from?

Westwego, LA is far enough from any federal soil-temperature station that the schedule uses Open-Meteo's ERA5-Land reanalysis as a modeled estimate. Modeled estimates are useful trend signals but less precise than in-situ readings; treat the schedule's confidence labels as guidance, not promises. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

Fertilizer

IN WINDOWMODERATE CONFIDENCE

Warm-season summer nitrogen^{17, 18}

A mid-summer nitrogen feeding sustains the bermudagrass or zoysia growth started in late spring, feeding the most active growth phase of the year. Skipping it leaves a thinner canopy heading into the late-summer disease and weed window.

Conditions are close to the action band. Monitor daily, the window typically opens within a few days.

Why this, why now

Safety details (REI, air-temp ceiling, pre-rain)

Conditions are not yet in the action band. The guidance below describes the safety constraints to plan around when the window opens.

Re-entry interval is not required for this product.

Air temperatures above 95°F can volatilize the product or stress the lawn. Wait for cooler conditions.

Air temperatures below 65°F slow uptake and reduce efficacy. Wait for warmer conditions.

Apply at least 24 hours before forecast rain so the product binds before runoff.

Fertilizer

IN WINDOWMODERATE CONFIDENCE

Summer iron (foliar) application^{19, 20}

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.

Conditions are close to the action band. Monitor daily, the window typically opens within a few days.

Why this, why now

Safety details (REI, air-temp ceiling, pre-rain)

Conditions are not yet in the action band. The guidance below describes the safety constraints to plan around when the window opens.

Keep pets and children off treated areas for 4 hours after application.

Air temperatures above 90°F can volatilize the product or stress the lawn. Wait for cooler conditions.

Air temperatures below 60°F slow uptake and reduce efficacy. Wait for warmer conditions.

Apply at least 4 hours before forecast rain so the product binds before runoff.

Cultivation

IN WINDOWMODERATE CONFIDENCE

Summer mowing-height adjustment (warm-season)^{21, 22}

Warm-season grasses grow most aggressively in summer and benefit from frequent, slightly-higher mowing — typically 1.5-2.5 inches for bermuda, 2-2.5 for zoysia, 3-4 for St. Augustine. Mowing too short scalps the lawn and exposes soil to weed seeds.

Conditions are close to the action band. Monitor daily, the window typically opens within a few days.

Why this, why now

Pest

IN WINDOWMODERATE CONFIDENCE

Chinch bug watch (warm-season)^{23, 24}

Chinch bugs feed on St. Augustine, zoysia, and bermudagrass during hot, dry stretches and create irregular brown patches that look like drought damage. Spotting them early — usually by parting the grass at the edge of a yellowing patch — is the difference between a localized treatment and a full-lawn rescue.

Conditions are close to the action band. Monitor daily, the window typically opens within a few days.

Why this, why now

No active tasks for your location.

About this schedule

Soil at 2 inches is currently 83°F. Chinch bug watch (warm-season) is in window now. Modeled estimate from Open-Meteo ERA5-Land (no station within range). First fall frost typically arrives around November 1.
