For warm-season lawns (bermuda, zoysia, St. Augustine), the best time to plant grass seed in Mississippi 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, and closes as soil cools back through 65°F, typically around October 18.
Soil Temperature in Mississippi
The current average 2-inch soil temperature across Mississippi is 78°F. Readings range from 68°F to 86°F, from 15 USDA and NOAA monitoring stations. Soil across Mississippi is running 5°F above the seasonal normal of 73°F for early October, based on 15 of 15 stations with historical records. Mississippi spans USDA hardiness zones 7b to 9a, crossing from cool-season into warm-season grass country. Last updated September 30, 2026.
Current Planting Conditions
Soil across Mississippi is cooling off its summer peak at an average of 78°F at 2 inches. The fall poa annua pre-emergent window is in play as readings fall through the 65–70°F band, and cool-season overseeding follows close behind.

- When to Apply Pre-Emergent in Fall: Stop Poa Annua at 70°F
Time fall pre-emergent ahead of poa annua germination.
- Fall Broadleaf Weed Control: The Best Kill Window of the Year
Fall is when broadleaf herbicide works hardest.
- Winter Overseeding Warm-Season Lawns with Ryegrass: The 65-70°F Window
