For warm-season lawns (bermuda, zoysia), the best time to plant grass seed in Alabama 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 18, 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.
