For warm-season lawns (bermuda, zoysia), the best time to plant grass seed in Louisiana is late spring into early summer, when soil is warming and a full growing season lies ahead. The window opens when 2-inch soil reaches 65°F and keeps rising. Soil stays above 65°F until about November 14, but seed sown after the summer peak cannot establish before dormancy, so the practical window closes by midsummer; the month-by-month table below shows where that falls.

Timing varies within Louisiana: your city page tracks the local window from its nearest station: see when to plant in New Orleans, when to plant in Baton Rouge or when to plant in Shreveport. Today's statewide reading is on the Louisiana soil temperature page.

Typical dates are computed from historical 2-inch soil temperature averages at 2 monitoring stations in Louisiana; your own window depends on your nearest station's readings.
