Tall Fescue Seasonal Care Calendar
FALL (Sept-Nov) is PEAK season — core aerate, overseed, apply heaviest fertilizer (2 apps), soil test, and lime if needed. This is when fescue grows fastest and recovers best. WINTER (Dec-Feb): fescue stays green in most climates. Minimal care needed. Mow occasionally if growing. Apply lime if fall soil test indicated low pH. SPRING (Mar-May): light fertilizer (0.5 lb N max), apply pre-emergent before soil hits 55°F, begin regular mowing at 3.0-3.5 inches, post-emergent for broadleaf weeds when temps are below 85°F. SUMMER (Jun-Aug): SURVIVAL MODE. Raise mowing height to 3.5-4.0 inches. Zero nitrogen. Water deeply but reduce frequency if brown patch risk is high. Apply preventive fungicide. Accept that fescue will look stressed — do not try to push growth.
Frequently Asked Questions
What is the most important season for fescue?
Fall, without question. September through November is when fescue grows fastest, recovers from summer damage, and builds root reserves for winter. Aerate, overseed, and fertilize in this window.
How do I get fescue through summer?
Raise mowing height to 3.5-4 inches. Stop nitrogen completely. Water deeply in the morning only. Accept that some brown patch may occur. The goal is survival, not growth.
Does fescue stay green in winter?
Yes, fescue stays green through winter until hard freezes. It goes dormant at 32°F and greens up again at 45°F soil temp in early spring. This is a major aesthetic advantage over bermuda.
