Fertilizing your lawn on the right schedule is one of the most impactful things you can do for its long-term health and appearance. Apply fertilizer at the wrong time of year and you waste money, encourage weeds, or even damage the grass you’re trying to improve. Apply it correctly and you’ll build a dense, resilient lawn that handles North Carolina’s challenging summer heat and periodic drought. This seasonal guide is designed specifically for homeowners in the Piedmont Triad — Guilford, Rockingham, and surrounding counties — where warm-season and cool-season grasses each have distinct fertilization windows.

Know Your Grass Type First

Before any fertilization schedule makes sense, you need to know what type of grass you have. The Piedmont Triad is a transition zone where both warm-season and cool-season grasses are grown, and their fertilization calendars are nearly opposite:

  • Warm-season grasses: Bermuda grass, Zoysia, Centipede, St. Augustine. These grasses grow actively in summer, go dormant in winter, and should be fertilized during their active growing season from late spring through summer.
  • Cool-season grasses: Tall fescue, fine fescue. These grasses grow most actively in fall and spring, go semi-dormant in summer, and are primarily fertilized in fall with optional light spring feeding.

Fertilizing Tall Fescue: A Seasonal Guide

Tall fescue is by far the most common lawn grass in Guilford County and throughout the Piedmont Triad. Many homeowners inherited fescue lawns or chose them for their relatively tolerant nature and ability to stay green year-round. Here is the ideal fertilization schedule for fescue in this region:

  • Early March (light spring application): Apply a light application of slow-release nitrogen fertilizer as the lawn comes out of winter dormancy. Keep rates modest — typically no more than 0.5 pounds of nitrogen per 1,000 square feet. Heavy spring feeding forces lush, disease-prone growth that struggles when summer heat arrives.
  • Skip summer: Do not fertilize fescue in June, July, or August. Summer-stressed fescue cannot use fertilizer effectively, and nitrogen applications during heat and drought can burn the lawn and increase disease susceptibility.
  • September (primary fall application): The most important fertilization timing for fescue in the Piedmont Triad. Apply a quality lawn fertilizer with nitrogen in September as temperatures cool and fescue enters its peak growing period. This feeding fuels root development going into winter.
  • November (secondary fall application): A second fall application about 6 to 8 weeks after the September feeding provides lasting nutrition for winter root development. Use a winterizer fertilizer with lower nitrogen and higher potassium content to harden the grass for cold weather.

Fertilizing Bermuda Grass: A Seasonal Guide

Bermuda grass is a warm-season lawn grass that thrives in the Piedmont Triad’s summer heat. It goes completely dormant and turns brown in winter, then greens up rapidly in late spring. Bermuda lawns require a different approach to fertilization than fescue:

  • Wait until green-up (late April to early May): Do not fertilize Bermuda until it shows consistent green color and is actively growing. Applying nitrogen to dormant or semi-dormant Bermuda primarily benefits weeds rather than the turf.
  • May through August (peak feeding period): Bermuda is a heavy feeder that benefits from regular nitrogen applications during its active growing season. Apply fertilizer every 4 to 6 weeks from May through August at a rate of 0.75 to 1 pound of nitrogen per 1,000 square feet per application.
  • Stop by mid-September: Cease fertilizing Bermuda 6 to 8 weeks before the first expected frost in the Piedmont Triad area, typically mid-October to early November. Late nitrogen applications can delay dormancy and increase cold damage risk.

Fertilizing Zoysia: A Seasonal Guide

Zoysia grass is increasingly popular in the Piedmont Triad for its drought tolerance and lush appearance. Like Bermuda, it is a warm-season grass that goes dormant in winter. Zoysia has lower fertilizer needs than Bermuda:

  • Late April or early May (first application): Begin feeding once the lawn is fully green and actively growing, typically late April to early May in Greensboro and Reidsville.
  • June or July (second application): One mid-summer application maintains color and density through the hottest months. Use a balanced fertilizer with controlled-release nitrogen.
  • Stop by August: Zoysia requires earlier cessation of feeding than Bermuda. Stop fertilizing by mid-August to allow the lawn to begin its natural transition toward dormancy.

Fertilizing Centipede Grass

Centipede grass is the most low-maintenance lawn grass available in North Carolina. It has minimal fertilizer needs and over-fertilizing is actually one of the most common mistakes centipede lawn owners make. The result is excessive thatch buildup, disease susceptibility, and what is called “centipede decline.” For centipede lawns, a single light application of a low-nitrogen fertilizer in May is usually all that is needed for the entire growing season. Never apply more than 1 to 2 pounds of nitrogen per 1,000 square feet per year total.

Soil Testing: The Foundation of Smart Fertilization

No fertilization schedule is complete without a soil pH test. North Carolina’s Piedmont soils are characteristically acidic, and low pH locks up nutrients that fertilizers provide — meaning you can apply the right fertilizer at the right time and still get poor results if your soil pH is too low. NC Cooperative Extension offers subsidized soil testing for homeowners. A pH test in early spring tells you whether to apply lime before your first fertilizer application. Correcting pH is the single highest-leverage action many Piedmont Triad homeowners can take for their lawns.
