Quick answer
Seed tall fescue in early fall, roughly September into October. Warm soil and cooling air give seedlings time to root before winter and before the next summer's heat.
Why Fall Beats Spring
Spring-seeded fescue has only a few months to root before Oklahoma summer heat, and many seedlings don't survive. Fall seeding also faces less weed competition.
Where Fescue Fits
Fescue is a cool-season grass that tolerates shade better than Bermuda. It works best under trees where Bermuda thins out.
Care Tips
- Keep seed moist until germination
- Mow taller than Bermuda
- Expect some summer stress and plan to touch up thin spots in fall
