Centipedegrass: Mowing Height, Seed Rate and Lawn Care
Quick answer
Centipedegrass is a low-input warm-season grass for zones 7 to 9 on acidic, sandy soil. Mow it at 1 to 2 inches, seed just 0.25 to 0.5 pounds per 1,000 square feet in 70 F soil, and feed only 0.5 to 2 pounds of nitrogen a year. Overfeeding and liming are what kill it.
Centipedegrass earned the nickname "the lazy man's grass" honestly. It is a slow-growing, light green warm-season grass that spreads by surface stolons, wants acidic sandy soil, and asks for less fertilizer than any other southern lawn grass. Across the coastal plain from the Carolinas through Georgia and Alabama to east Texas, it is the default lawn for people who want to mow and little else.
The flip side is that centipede is easy to kill with kindness. Too much nitrogen, or lime applied without a soil test, produces the classic pattern extension agents call centipede decline. Seed rates here are the lowest of any lawn grass, so measure carefully with the grass seed calculator, keep feedings tiny with the fertilizer calculator, and treat the lime calculator as off limits unless a soil test reads below pH 5.0.

What are the key numbers for a centipede lawn?
| Trait | Centipedegrass |
|---|---|
| Season type | Warm-season; dormant and tan through winter |
| USDA zones and region | Zones 7 to 9; the Southeast coastal plain from the Carolinas to east Texas |
| Mowing height | 1 to 2 in |
| Seeding rate | 0.25 to 0.5 lb per 1,000 sq ft new; about 0.25 lb overseeding, the lightest rate of any lawn grass |
| Germination | 14 to 28 days once soil holds 70 F, slow and easily washed out |
| Shade tolerance | Moderate; takes light shade, thins under dense canopy |
| Drought tolerance | Fair; shallow roots mean it wilts before bermuda or bahia does |
| Wear and traffic | Poor; it repairs damage slowly and is not a play-area grass |
| Nitrogen per year | 0.5 to 2 lb N per 1,000 sq ft, and less is usually better |
| Soil pH | 5.0 to 6.0; it is one of the few lawn grasses that prefers acidic soil |
| Spreading habit | Surface stolons only, no rhizomes |
| Main drawback | Centipede decline from overfeeding, over-liming or thatch |
Ranges reflect common southeastern extension guidance. Do not lime a centipede lawn without a soil test showing pH below 5.0.
When does centipede grass green up?
Centipede is one of the last warm-season grasses to wake up in spring, often weeks behind neighboring bermuda lawns, and greening up too fast is a bad sign rather than a good one. This timeline uses soil temperature cues instead of dates.
| Season | Soil temperature cue | Main tasks |
|---|---|---|
| Early spring | Soil 50 to 55 F, lawn still tan | Pre-emergent before soil holds 55 F; no nitrogen, which causes spring green-up problems |
| Late spring | Soil 65 to 70 F, lawn fully green | Wait for full green-up, then apply the single light feeding if the lawn needs one; seed or plug bare areas |
| Summer | Soil 75 F and above | Mow at 1 to 2 in; water about 1 in a week in drought; spot-treat weeds per the label |
| Late summer to early fall | Soil cooling through 70 F | Stop nitrogen; a potassium feeding supports winter hardiness; dethatch only if thatch exceeds half an inch |
| Fall | Soil below 65 F | Fall pre-emergent for winter annual weeds; keep leaves raked off the thinning canopy |
| Winter | Lawn dormant | Leave it alone; centipede dislikes traffic on dormant turf |
A centipede lawn that greens up and then yellows in patches is usually showing decline from excess nitrogen, high pH or thatch rather than a disease.
How much fertilizer does centipede grass need?
Between 0.5 and 2 pounds of nitrogen per 1,000 square feet per year, and many healthy centipede lawns get a single feeding of about half a pound. This is a quarter of what a hybrid bermuda lawn wants, and it is the single most important number on this page. Excess nitrogen produces lush growth, thatch, and the yellowing dieback of centipede decline.
Because the rate is so small, weigh the product rather than eyeballing it, and spread with a unit you can dial down such as the Scotts Whirl Hand-Powered Spreader on small lawns. Yellowing between the leaf veins is usually an iron shortage on soil whose pH has crept above 6.0, not hunger, and a chelated iron product greens it without pushing growth. Confirm with a test first: how to test soil pH covers sampling, and the best soil test kits compares options.
How do I plant centipedegrass?
At 0.25 to 0.5 pounds per 1,000 square feet, a 5,000 square foot lawn needs only 1.25 to 2.5 pounds of seed. That tiny quantity is hard to spread evenly, so most guidance is to mix the seed with dry sand to bulk it up. Seed in late spring or early summer once soil holds 70 F, and expect 14 to 28 days to germinate plus a full season to cover.
The Scotts Turf Builder Centipede Grass Seed and Mulch, 5 lb pairs seed with mulch and is labeled for 665 square feet of new lawn, a heavier application than the bare-seed rate because most of the bag weight is mulch. Faster options are centipede sod or plugs. Keep new seed damp and light: a fine spray from the Dramm Revolver Heavy Duty Metal Hose Nozzle, 9 Patterns will not wash out seed the way a hose stream does.
What gear fits a centipede lawn?
Very little, which is the point of this grass. A mower, a small spreader and a soil test cover most of the year.

Frequently asked questions
Why is my centipede grass turning yellow?
The two usual causes are iron shortage and too much nitrogen. Yellowing between the veins of new leaves, especially where soil pH has risen above 6.0, points to iron, which a chelated iron product corrects without forcing growth. Uniform yellowing with thick thatch after heavy feeding points to centipede decline. A soil test separates the two, and guessing usually makes decline worse.
Should I lime a centipede lawn?
Almost never without a soil test first. Centipedegrass prefers acidic soil around pH 5.0 to 6.0, so routine liming, which helps most other lawn grasses, pushes pH into the range where centipede cannot take up iron and starts to decline. Only lime if a test shows pH below about 5.0, and then apply at the rate the test recommends rather than a standard bag rate.
Can centipede grass grow in shade?
It takes light or filtered shade, roughly four to six hours of sun, which puts it ahead of bermudagrass and behind St. Augustinegrass. Under a dense canopy it thins, stretches and gives ground to weeds and moss. In shaded areas mow at the top of the 1 to 2 inch range and keep nitrogen at the low end, since shaded centipede is even more sensitive to overfeeding.
How do I get rid of weeds in centipedegrass?
Carefully, because centipede is sensitive to several common lawn herbicides. Match the product label to centipedegrass before buying, since some broadleaf concentrates and most weed and feed products either exclude it or require a reduced rate. Apply at the labeled rate on a lawn that is actively growing, never on dormant or drought-stressed turf, keep kids and pets off until dry, and do not spray in wind.
