For warm-season lawns (bermuda, zoysia), 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. Soil stays above 65°F until about October 19, 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.

Region	Typical planting window opens	Stations
Northern Mississippi	April 26	6
Central Mississippi	April 4	6
Southern Mississippi	April 3	4
