Centipede → Tall Fescue Conversion Plan (Sanford, NC – Zone 7b)

This document outlines the full process of converting an existing centipede lawn into a Tall Fescue lawn.
This plan is tailored for Sanford, North Carolina (Zone 7b), where centipede struggles and Tall Fescue performs much better year-round.

Centipede has major issues in NC residential lots:

• Spreads aggressively into garden beds and sidewalks
• Turns brown November–May
• Thatch buildup every spring
• Sensitive to many herbicides
• Requires low nitrogen
• Does poorly in high-traffic areas
• Looks patchy and weak without perfect pH and soil care

Tall Fescue is the opposite:

• Stays green year-round
• Thick, upright growth
• Works great with normal fertilizers (Sunday included)
• Responds well to overseeding
• Less invasive into beds
• Handles traffic better

The conversion happens gradually over one full year (with two fall overseeding cycles for perfection).

1. Stop managing lawn like centipede.
2. Begin patching in Tall Fescue during spring.
3. Do a FULL Tall Fescue overseed in September.
4. Repeat next September for 95% fescue dominance.

Centipede will naturally thin out as mowing height increases and nitrogen levels rise.

• Lightly rake centipede thatch by hand (NO power dethatcher).
• Spot-treat weeds (clover, dandelion) with 2,4-D or Sunday Weed Warrior.
• Optional: Patch-seed thin areas with Tall Fescue.
• Reminder: You must skip pre-emergent if seeding patches.

• Continue spot-spraying weeds.
• Mow high (3.5–4“) to favor fescue and weaken centipede.
• Light fertilizer via Sunday Feed.

• Water deeply once per week.
• Avoid heavy nitrogen in July heat.
• Never overseed in summer.

1. Mow existing centipede very low (1 inch).
2. Bag and remove loose material.
3. Core aerate the entire lawn.
4. Broadcast Tall Fescue seed over all turf areas.
5. Apply starter fertilizer.
6. Water lightly 1–2x per day for 2–3 weeks.

This begins the conversion.

• After 4–6 weeks, apply Weed & Feed (okay now that fescue is established).
• Raise mowing to 4”.
• Fix thin areas with more seed.

• Fescue stays green.
• Apply Sunday Winterizer if desired.

Repeat the September overseed for:

• Maximum thickness
• Full suppression of centipede
• A consistent Tall Fescue appearance

After the second fall overseed, you will have converted roughly 90–95% of the lawn.

• Mow at 3.5–4“.
• Fertilize spring and fall.
• Avoid pre-emergent in September seeding window.
• Overseed lightly every fall to maintain density.

Centipede will naturally weaken as you maintain the yard for fescue:

• Higher mowing height shades it out
• Regular nitrogen fertilization suppresses it
• Aeration & seeding fill in bare spots

If centipede persists in certain patches:

• Glyphosate spot treatment in midsummer works
• Re-seed the patch in September

• Sunday “Grow Green” or “Lawn Strength”
• Sunday Weed Warrior (spot-treatment only)

• Sunday Seed Starter for full overseed
• Sunday Fall Fortify after establishment

• Sunday Winterizer (optional)

Use Tall Fescue blend with:

• Turf-type tall fescue (TTTF)
• Heat-tolerant varieties (Houndog 7, Falcon V, Rebel, Titan, Crossfire, etc.)

Sunday’s seed is fine for patching or even for full overseed.

Apply at:

• Full overseed: 6–8 lbs per 1,000 sq ft
• Patch repair: 3–4 lbs per 1,000 sq ft

• Leaf rake
• Lawn mower with bag
• Aerator (rental is fine)
• Hose or sprinklers
• Sunday fertilizers
• Fescue seed

By following this plan:

• Lawn is 60–70% Tall Fescue
• Centipede begins thinning
• Color stays greener through winter
• Far fewer weeds

• Lawn is 90–95% Tall Fescue
• Centipede nearly gone
• Deep green all year
• Minimal thatch
• No more creeping runners into garden beds
• Mowing is easier
• Looks like a “real” NC cool-season lawn
