Lawn Grass Types Compared: 10 Grasses, Where Each Survives, and the Month to Plant It

Pick the wrong grass and no amount of fertilizer, water or mowing will save it: Texas A&M reports that severe winters can kill St. Augustine in the northern third of Texas, and NC State calls Kentucky bluegrass unsuitable for the hot Carolina coastal plain. Pick the right one and most of the work gets easier. This guide puts ten common US lawn grasses side by side, using the selection tables from four state extension services, and adds what those tables leave out: how many hours of sun each grass needs, the soil temperature to plant at, and a month-by-month calendar for each group.

Cool-season, warm-season or transition zone: which group fits your yard?

Start with your summer, not your winter. NC State Extension defines cool-season grasses as those with optimum growth between 60°F and 75°F, and warm-season grasses as those that grow best between 80°F and 95°F. That one difference decides when a grass is green, when you feed it and when you plant it.

60–75°F vs 80–95°F The temperature band each group grows best in. Cool-season grasses peak in spring and fall; warm-season grasses peak in summer and go dormant after the first heavy frost.

• Cool-season grasses (tall fescue, Kentucky bluegrass, perennial ryegrass, fine fescue) grow in spring and fall, slow down in summer and stay reasonably green in winter. UF/IFAS calls them northern-grown grasses; further south, NC State limits most of them to the mountains and piedmont.
• Warm-season grasses (bermuda, zoysia, St. Augustine, centipede, bahia, buffalo) are slow to green up in spring, grow hardest in summer and turn brown after the first heavy frost. The University of Georgia puts their growing season at roughly May to October in Georgia.
• The transition zone is the band where neither group is comfortable. NC State’s lawn establishment guide describes its piedmont as often too cold in winter for warm-season grasses and too hot in summer for cool-season grasses, and suggests warm-season grass for sunny southwest-facing lawns and cool-season grass for north-facing ones. Kansas State publishes planting schedules for both groups, and in Georgia tall fescue reaches only to about Griffin. In this band the choice is between a cool-season lawn that stays green in winter and a warm-season lawn that turns brown, and shade often settles it.

Whichever group you choose, plant only that group. The University of Georgia’s selection guide says mixing cool-season and warm-season species in the same lawn should be avoided; each group’s seasonal growth pattern sets the timing of its care.

The 10 lawn grasses compared

Bermuda takes the most heat and foot traffic, with zoysia close behind; St. Augustine takes the most shade among warm-season grasses; tall fescue is the all-rounder of the cool-season group. The first table shows where each grass does best and what it tolerates; the second shows how to grow it.

Ratings summarise NC State’s Tables 1a–1c, UF/IFAS Table 1, UGA’s species notes and Texas A&M Table 2; the sources sometimes rate a grass one step apart.

The takeaway from the second table: mowing heights run from under an inch for bermuda to 4 inches for bahia and St. Augustine, and annual nitrogen runs from 1 pound per 1,000 square feet for bahia and centipede to as much as 6 for a high-input hybrid bermuda lawn.

Heights, nitrogen and dates from NC State’s Carolina Lawns (piedmont tables, mountain tables where noted, so the tall fescue and bluegrass nitrogen ranges come from different regions); zoysia seed cultivars from UGA; St. Augustine seed from UF/IFAS; buffalo grass from Texas A&M and Kansas State.

The grass seed calculator turns the seeding rates above into pounds for your lawn’s square footage.

The six warm-season grasses

Bermuda: best for sunny, hard-used lawns in the South

• Strength: NC State calls it extremely drought tolerant; it grows fast on any soil, withstands wear and recovers quickly from damage.
• Sun: full sun. The University of Georgia found the cultivars Celebration and TifTuf kept acceptable quality down to 5.5 hours of filtered sun after six years under hardwood shade, but says bermuda performs best with 8 hours or more.
• Upkeep: high. At low heights NC State says to mow at least twice a week.
• Watch out: it spreads by runners above and below ground into flower beds. One fix is a buried barrier; see how to keep grass out of a raised bed.

Zoysia: best for a dense, low-input lawn that takes some shade

• Strength: a very dense, wear-tolerant turf that NC State says rarely needs irrigation to survive in North Carolina. It grows more slowly than bermuda, so you mow less.
• Sun: some cultivars kept acceptable quality with as little as 4 to 4.5 hours of filtered sun in Georgia’s trials; all do best with 8.
• Upkeep: low to moderate, at 1 to 2 pounds of nitrogen a year according to UGA (NC State’s piedmont table gives 1 to 3).
• Watch out: the stiff leaves need sharp mower blades. NC State rates zoysia very slow to establish, and UGA says it is planted mostly as sod, sprigs or plugs. Our zoysia grass guide sets out plug spacing, fill-in times and cultivars.

St. Augustine: best for shady lawns near the Gulf and Atlantic coasts

• Strength: Texas A&M rates it the most shade-tolerant warm-season grass, and NC State calls it very shade and salt tolerant.
• Sun: UGA found it keeps acceptable quality with 5 to 6 hours of filtered sun.
• Upkeep: moderate. It grows fast, so mow at 2.5 to 4 inches; NC State caps feeding at 4 pounds of nitrogen a year and warns that heavy feeding and watering build thatch.
• Watch out: NC State calls it the least cold-tolerant lawn grass, and Texas A&M says severe winters can kill it in the northern third of Texas. It cannot be seeded, and it does not take heavy traffic.
• Full guide: St. Augustine grass: plugs, shade limits and the 5-minute chinch bug test covers cultivars, plug spacing, a month-by-month calendar and a symptom table.

Centipede: best for a low-maintenance lawn on acid soil

• Strength: needs little fertilizer and infrequent mowing. UGA puts its yearly nitrogen need at 1 to 2 pounds, with the lower end usually enough.
• Soil: acid. NC State says it grows best near pH 5.5, and UGA gives a maintenance range of 5.0 to 6.0 and recommends a zero-phosphorus fertilizer unless a soil test says otherwise.
• Upkeep: low. Our centipede grass care guide covers the pH, mowing height, nitrogen rate and monthly calendar.
• Watch out: NC State lists what it does not tolerate: traffic, compaction, high pH, high phosphorus, excess thatch, drought and heavy shade. It is also sensitive to many common herbicides.

Bahia: best for big, sandy, unirrigated yards in Florida and south Georgia

• Strength: UF/IFAS rates its drought tolerance and nematode tolerance excellent and its maintenance low.
• Soil: acid and sandy, which is why it shows up in our guide to grass seed for Florida’s sandy soil.
• Upkeep: low. Mow at 3 to 4 inches by UF/IFAS’s range (NC State gives 2 to 4); UF/IFAS notes that low-maintenance lawns are often mowed mainly to remove seedheads.
• Watch out: it forms an open, low-density turf. The University of Georgia goes further and says that in most lawns bahia is considered a weed.
• Full guide: bahia grass care: Argentine vs Pensacola, mowing the seedheads, and when it counts as a weed.

Buffalo grass: best for dry, sunny lawns on the plains

• Strength: a grass that Texas A&M rates as having a very low water requirement, excellent drought tolerance and high cold tolerance.
• Climate: best where annual rainfall is 25 inches or less. When it is watered heavily or planted in rainy East Texas, weeds and other grasses invade it.
• Upkeep: low; mow at 2.5 to 3 inches. Texas A&M’s table lists mowing every 7 to 14 days, if you mow at all.
• Watch out: it does best in full sun and tolerates little shade or traffic. For a dog-friendly take on it, see switching an arid yard to buffalo grass.

The four cool-season grasses

Tall fescue: best all-round choice for the transition zone and the north

• Strength: Purdue’s turf program recommends turf-type tall fescue for a new lawn because it needs less nitrogen, water and insecticide than Kentucky bluegrass. NC State calls it the best grass to plant if you want a year-round green lawn.
• Sun: sun or medium shade.
• Upkeep: moderate; it needs more frequent mowing than bluegrass, according to Purdue.
• Watch out: it is a bunch-type grass, so bare spots don’t fill in by themselves; NC State says to reseed them. NC State also warns it will not perform well in full sun in the coastal plain, especially on sandy soil.

Kentucky bluegrass: best for a soft lawn that repairs itself in cool regions

• Strength: it spreads by rhizomes (underground stems), which NC State says make excellent sod and help it recover from damage.
• Sun: sun or moderate shade; NC State says it generally grows better than tall fescue in moderate shade.
• Upkeep: it needs mowing less often than tall fescue, but Purdue says it takes more nitrogen, water and insecticide, and it wants fertile, limed, well-drained soil.
• Watch out: UGA notes it can go semi-dormant in hot weather, and NC State says it is not suitable for the coastal plain.
• Full guide: Kentucky bluegrass care: rhizomes, seeding dates and a symptom table covers mowing, nitrogen by program and a month-by-month calendar.

Perennial ryegrass: best as a fast-starting partner in a seed mix

• Strength: NC State rates bluegrass and ryegrass mixes fast to establish and gives a mix rate of 2.5 pounds per 1,000 square feet, with bluegrass making up 60 percent of the mix by weight.
• Sun: NC State rates the mix as good in shade.
• Upkeep: moderate.
• Watch out: Purdue advises against perennial ryegrass for a new lawn. Don’t confuse it with annual ryegrass, which dies after one season; see annual vs perennial ryegrass.

Fine fescue: best for shady, low-fertility spots where other grasses thin out

• Strength: NC State notes fine fescues (creeping red, chewings and hard fescue) for their tolerance of shade, drought and poor soil compared with other cool-season grasses.
• Sun: part shade; UGA says it is a common part of the “shade mixtures” sold at retail outlets.
• Upkeep: low. Purdue says fine fescues are great if you leave the lawn unmown, but advises against them at normal lawn height.
• Watch out: NC State says they may not persist in sun, high heat, wet soil, humidity or heavy traffic, and most are bunch types, so seed them with Kentucky bluegrass.

Shade: how many hours of sun each grass needs

No lawn grass likes deep shade, but some tolerate more than others. The University of Georgia’s shade trials give the most useful numbers, because they are in hours of sun rather than vague “partial shade” labels.

• 8 hours or more: what bermuda and zoysia need to perform at their best.
• 5.5 hours of filtered sun: the lowest level at which Celebration and TifTuf bermuda stayed acceptable after six years.
• 5 to 6 hours: the minimum for St. Augustine.
• 4 to 4.5 hours: as little as this for some shade-tolerant zoysia cultivars, the lowest figure in UGA’s guide.

In cool regions, fine fescue and Kentucky bluegrass are the shade options; NC State’s mountain table rates a bluegrass, tall fescue and fine fescue mix highest for shade among its cool-season options. Count the hours of direct or filtered sun on the spot in midsummer, when trees are in full leaf. Four hours is the lowest figure in UGA’s guide, so below it a moss lawn or a ground cover from our lawn alternatives guide is the safer plan.

Seed, plugs or sod: time it by soil temperature

Plant when the soil, not the calendar, is ready for your grass group. The dates in the table above are North Carolina’s; the soil temperatures below explain why they fall where they do and let you shift them for your own region.

• Warm-season seed: germinates and develops well when soil stays at 65–70°F, which usually means daytime air at 80°F or more, according to NC State Extension in Pender County. Full establishment from seed can take two to six months.
• Warm-season sod and plugs: NC State says sod will not produce roots until soil stays above 55°F for several weeks. Kansas State calls June the best month for planting warm-season grass there and May the best month for zoysia plugs and sprigs. Earlier plantings are slow to establish and often overrun by weeds.
• Cool-season seed: sow in late summer, while the soil is still warm. Iowa State gives mid-August to mid-September as the best window and says seeding from late May to mid-August is “extremely difficult and usually unsuccessful”. Penn State says a late-summer seeding gives new grass two cool growing seasons before its first summer heat. Our fall lawn care guide walks through the steps.
• Cool-season cut-off: Kansas State treats October 15 as generally the last day to plant a lawn in fall; Penn State does not suggest seeding later than mid-October in most of Pennsylvania.
• Dormant seeding: if you miss the fall window, Kansas State says to sow once soil averages below 40°F, normally mid- to late November, so the seed waits until spring to germinate.

Plugs are the cheap middle path for grasses that spread by runners. NC State spaces them on 6-inch or 12-inch centers, depending on how fast you want cover. Bunch-type grasses such as tall fescue, ryegrass and fine fescue cannot be plugged, because they don’t spread sideways to fill the gaps.

Lawn calendar by month, with feeding dates by grass type

Cool-season lawns get most of their work in late summer and fall; warm-season lawns get theirs from late spring to late summer. The calendar below follows the North Carolina piedmont, the middle of the transition zone. NC State’s own tables show how it shifts: in the cooler mountains, tall fescue is seeded from mid-August and fed in March, August and October; on the warmer coastal plain, bermuda is fed from April and hybrid bermuda and zoysia are planted from March.

Feeding months from NC State’s basic program for the piedmont (Table 3b); planting dates from NC State Table 2b and Kansas State; seeding cut-offs from Penn State, Iowa State and Kansas State; the 65°F feeding trigger from UGA; pest timing from Penn State.

The fertilizer months differ by grass more than the calendar can show, so here is NC State’s basic piedmont program grass by grass. The “basic” program is the lower-input one; NC State’s high-maintenance program adds feedings.

To turn “1 pound of nitrogen” into pounds of product, NC State’s rule is to divide 100 by the first number on the bag: a 16-4-8 fertilizer needs 6.25 pounds per 1,000 square feet. The fertilizer calculator does the same sum for any bag and lawn size. Leaving clippings on the lawn can cut fertilizer needs by 20 to 30 percent, according to NC State.

For the hot months, our summer lawn care guide covers mowing height and deep watering in detail.

Mistakes that sink a new lawn

• Reading “excellent drought tolerance” as “needs less water”. UF/IFAS explains that grasses rated excellent survive drought by going dormant, which does not necessarily mean less irrigation: the grass still needs water to stay green. Bahia and St. Augustine hold their color longer in drought; zoysia and centipede lose it quickly.
• Buying Kentucky 31 when you want a lawn. UGA points out that K-31 tall fescue was originally used for forage, pasture and erosion control. Turf-type tall fescues are darker, finer, denser and more shade tolerant.
• Confusing tall fescue with fine fescue. They are different species. UGA notes tall fescue has wider blades and is better suited to Georgia’s conditions; fine fescue is the shade and low-fertility specialist.
• Feeding warm-season grass too early. UGA advises waiting until soil at 4 inches is consistently 65°F and rising, which can reduce large patch disease in centipede and zoysia.
• Treating centipede like other grasses. UGA says it generally needs no phosphorus and no lime unless a soil test calls for it, and NC State lists high pH and high phosphorus among the things it does not tolerate.
• Overfeeding St. Augustine. Heavy fertilizer and water build thatch; NC State’s ceiling is 4 pounds of nitrogen a year.
• Mowing too short. UF/IFAS notes that taller mowing gives more leaf surface, deeper roots and better drought and shade tolerance, and that mowing below the recommended height invites weeds, insects and disease. Take off no more than one-third of the leaf at a time, as NC State advises; Penn State calls a dense, well-managed turf the first step in weed control against crabgrass and other weeds.

Picking a cultivar: use NTEP trial data

Choosing the species is half the decision; the cultivar (variety) on the bag matters too. Kansas State points buyers to the National Turfgrass Evaluation Program (NTEP), a non-profit that runs five-year cultivar trials with more than 35 land-grant universities. Each trial is rated at usually 10 to 20 or more locations, the raters don’t know which cultivar is in which plot, and the results are free to read. Look for a test site with a climate like yours, then check the seed tag against the cultivars that rated well there.

For cool-season seed, NC State recommends a blend of two or three cultivars rather than one, which broadens the genetic base and gives the lawn a better chance of withstanding a variety of challenges.

Which grass should you choose?

• If you live in the transition zone and want green all year, choose turf-type tall fescue.
• If you have full sun, heat and kids or dogs on the lawn, choose bermuda.
• If you want a dense warm-season lawn with less mowing and some shade, choose zoysia.
• If you live near the Gulf or south Atlantic coast and have shade, choose St. Augustine.
• If your soil is acid and you want the least work in the Southeast, choose centipede.
• If your summers are dry and you want to water little on the plains, choose buffalo grass.
• If the spot gets less than about four hours of sun, skip grass and look at clover, creeping thyme or moss.

Frequently asked questions

What are the main types of lawn grass?

There are two groups. Cool-season grasses such as tall fescue, Kentucky bluegrass, perennial ryegrass and fine fescue grow best at 60–75°F. Warm-season grasses such as bermuda, zoysia, St. Augustine, centipede, bahia and buffalo grass grow best at 80–95°F.

What is the best grass for shade?

Among warm-season grasses, St. Augustine and some shade-tolerant zoysia cultivars, which keep acceptable quality with as little as 5–6 and 4–4.5 hours of filtered sun, according to the University of Georgia. Among cool-season grasses, fine fescue, often mixed with Kentucky bluegrass. Below about four hours of sun, the lowest figure in UGA’s guide, a lawn alternative is the safer plan.

Can you mix warm-season and cool-season grass?

The University of Georgia says to avoid it, because each group needs mowing, feeding and weed control at different times. Pick one group and manage the lawn for it.

When should you plant grass seed?

Cool-season seed in late summer and early fall: mid-August to mid-September in Iowa State’s guidance, September 1 to October 1 in the North Carolina piedmont, and Kansas State treats October 15 as generally the last day. Warm-season seed from spring into early summer, once soil holds 65–70°F.

Which lawn grass needs the least maintenance?

In the Southeast, centipede and bahia: NC State’s piedmont table gives bahia about 1 pound of nitrogen per 1,000 square feet a year and centipede 1 to 2; bahia, though, makes an open turf that UGA considers a weed in most lawns. On the dry plains, buffalo grass, which Texas A&M rates as having a very low water requirement.
