Tall Fescue Seeding Guide
FALL seeding is non-negotiable for fescue — the window is September through mid-October when soil temps are 50-65°F. Spring seeding is possible but risky: seedlings face summer heat before roots establish, and you cannot apply pre-emergent in seeded areas. Overseeding rate: 6-8 lbs per 1,000 sq ft. New lawn rate: 8-10 lbs per 1,000 sq ft. Seed-to-soil contact is critical — core aerate or slit-seed, do not just broadcast on top of existing turf. Keep seed moist (not soaked) for 14-21 days until germination. Use TTTF blends with 3+ varieties for disease resistance and genetic diversity.
Frequently Asked Questions
When should I seed fescue?
September through mid-October is the ideal window. Soil is still warm for germination, air is cooling, and weed competition drops. Spring seeding works but expect more weed pressure.
How much seed should I use for overseeding?
6-8 lbs per 1,000 sq ft for overseeding existing lawns. 8-10 lbs per 1,000 sq ft for new lawns or heavy renovation. Use TTTF blends with 3+ varieties for disease resistance.
Why is annual overseeding important for fescue?
Fescue grows in clumps and cannot spread to fill bare spots. Without overseeding, thin areas get thinner and weeds move in. Annual overseeding is the fescue equivalent of bermuda's natural spreading.
Should I aerate before overseeding?
Yes. Core aeration before overseeding dramatically improves seed-to-soil contact. Aerate, then seed, then apply starter fertilizer. This is the fall renovation trifecta for fescue.
