Triangle planting calendar

When to plant grass in the Triangle

Grass goes in the ground on a schedule, and planting off-season is how good money turns into a thin lawn. Pick a date and this tells you what is worth planting now, what opens up soon, and what to hold off on. Dates and rates are for the Triangle, in the North Carolina piedmont.

Seed math

How much seed do you actually need?

Every rate on this page is per 1,000 square feet. Measure the lawn once and let the calculator do the multiplication, so you buy the right bag instead of guessing at the store.

Triangle planting dates and rates

Optimum planting windows, soil temperatures and seeding rates for the piedmont.

  • Bermuda Grass

    Best window
    April 1 to July 31
    Soil
    65°F soil and rising
    Look for
    After the last frost, once nights stay warm
    Seed
    1 to 2 lb of seed per 1,000 sq ft

    Hybrid bermuda goes down as sprigs rather than seed (about 3 to 10 bushels broadcast).

  • Zoysia Grass

    Best window
    April 1 to July 31
    Soil
    70°F soil or warmer
    Look for
    Warm days and warm nights, past the frost
    Seed
    1 to 2 lb of seed per 1,000 sq ft

    Often planted from sprigs or plugs, since seeded zoysia is slow to fill in.

  • Centipede Grass

    Best window
    March 1 to July 31
    Soil
    70°F soil or warmer
    Look for
    Settled spring warmth, no more cold snaps
    Seed
    0.25 to 0.50 lb of seed per 1,000 sq ft
  • St. Augustine Grass

    Best window
    April 1 to July 31
    Soil
    70°F soil or warmer
    Look for
    Warm and frost-free, from sod or plugs
    Seed
    about 1 lb of seed per 1,000 sq ft

    Usually established from sod or plugs rather than seed.

  • Bahia Grass

    Best window
    March 1 to June 30
    Soil
    65°F to 75°F soil
    Look for
    Warming spring soil
    Seed
    5 lb of seed per 1,000 sq ft
  • Tall Fescue

    Best window
    September 1 to October 1
    Soil
    60°F to 65°F soil
    Look for
    As summer heat breaks and nights cool
    Seed
    6 lb of seed per 1,000 sq ft
  • Kentucky Bluegrass and Tall Fescue mix

    Best window
    September 1 to September 15
    Soil
    60°F to 65°F soil

    Early fall, cooling nights
    Seed
    1 lb bluegrass plus 5 lb tall fescue per 1,000 sq ft
  • Bluegrass, Tall Fescue and Fine Fescue mix

    Best window
    August 15 to September 15
    Soil
    55°F to 65°F soil
    Look for
    Late summer, as the heat eases
    Seed
    1 lb bluegrass plus 5 lb tall fescue plus 1 lb fine fescue per 1,000 sq ft

Windows and rates are from NC State Extension's Carolina Lawns planting table for the piedmont. Your own soil, sun, and season vary, so a soil test and your local extension office are the last word on your lawn.

Common questions

When is the best time to plant grass seed in the Triangle?
It depends on the grass. Tall fescue and the cool-season mixes go down in the fall, roughly September into early October, which is the single best seeding window for most Triangle lawns. The warm-season grasses like bermuda, zoysia, centipede and St. Augustine go in during late spring into summer instead. The calendar above tells you what fits today's date.
When should I plant tall fescue in Raleigh?
September 1 to October 1 is the optimum window for the piedmont, at about 6 pounds of seed per 1,000 square feet. Fall seeding lets it root in before winter and take off the next spring. Spring seeding is a weaker option because the grass barely establishes before summer heat hits it.
Can I plant grass seed in summer in North Carolina?
For warm-season grasses, yes, late spring into summer is their window. For cool-season grasses like tall fescue, summer is the worst time, since the heat stresses new seedlings. If it is midsummer and you want a fescue lawn, the honest answer is usually to wait until fall.
