Having a suitable type of grass can mean the difference between a constant struggle to keep your grass green and an easy-going turf that provides season-long beauty and enjoyment. With all the choices, how do you decide which type of grass is the best? Here's some straightforward advice for picking the suitable grass for your landscape.

Narrow Your Choices

Where you live is the most critical factor affecting how types of grass will perform.

Northern Zone In the northern United States and Canada, where summers are moderate and winters often are cold, cool-season types of grass such as Kentucky bluegrass, perennial ryegrass, and tall fescue are the primary choices.

Southern Zone The Southern Zone, with hot summers and moderate winters, provides a climate where warm-season types of grass thrive. St. Augustinegrass, Bermudagrass, centipedegrass, and zoysiagrass are the most common.

Transition Zone This region has hot summers and cold winters, making it the most challenging area for lawns: Cool-season grasses struggle in the summer heat, while warm-season types can remain brown for as much as half of the year and may be prone to winter damage. Tall fescue is a popular choice in the Transition Zone because it exhibits good tolerance to both cold and heat and stays green most of the year. Bermudagrass, zoysiagrass, and Kentucky bluegrass also are grown in the Transition Zone.

Consider the Site

Next, think about the conditions in your yard. If there are no particular challenges, you should get good results from any of the primary types of grass for your region. For difficult sites with deep shade, lack of water, or salty soils, other species will adapt better to the specific conditions.

Low-Input Areas: Buffalograss—hardy throughout much of North America—is an excellent choice for an out-of-the-way area that's hard to supply with water or lawn fertilizer. Fine-leaf fescues also are suitable for low-input sites. Centipedegrass is a good choice for low-maintenance sites in the Southeast.

Shaded Sites: Fine-leaf fescues are the most tolerant of shady sites. In the South, most varieties of St. Augustine are fairly shade-tolerant except for the Floratam variety.

High-Traffic Sites: In the North, blends of Kentucky bluegrass and perennial ryegrass work well for high-traffic areas. In the South, Bermudagrass is preferred for its ability to recover rapidly from wear.

Seed companies often package mixes containing several types of grass selected for a particular site—sunny, shady, dry, or high-traffic, for example. They do the homework of devising the best mixes in the proper ratios, and the resulting lawn performs better than if you plant a single species.

Salty-Sites or Sites Using Effluent Water: Seashore paspalum is extremely salt-tolerant, making it excellent for sandy coastal sites affected by salt sprays or where effluent water with high salt levels is used for irritation.

Does the Type of Grass Really Matter?

In a word, yes. Each type of grass is available in several (sometimes many) varieties, offering variations in texture, color, and growth rate. Visually, the differences may be subtle, but newer varieties often have unseen advantages. For example, they might better tolerate diseases, pests, or harsh weather. No-name or generic seed, though cheaper, is usually not worth the savings because you might end up with an older variety prone to problems.

Use a mix of varieties to get the best performance from species such as tall fescue, perennial ryegrass, and Kentucky bluegrass. Though you can create your mix, it's more convenient to use prepackaged mixes formulated for specific regions. Generally, you won't go too far wrong if you stick to recognized brands and buy seeds from reputable garden centers, which tend to stock current varieties.

Cool-Season Types of Grass

Cool-season grasses, adapted to northern climates, thrive in spring and fall and stay green all winter where temperatures remain moderate. (They'll go dormant in northern areas.) However, they don't enjoy summer heat and often turn brown without plenty of supplemental water.

1. Kentucky Bluegrass

Kentucky bluegrass is the most common type of grass for northern lawns; it's also planted in the Transition Zone and on the West Coast (where the ocean's influence moderates summer heat). Kentucky bluegrass has dark color and medium texture. For best results, plant a mix of several varieties or blend with perennial ryegrass.

Pros: Fills in bare spots on its own; creates a beautiful lawn; tolerates harsh winters

Cons: Intolerant of shade; prone to thatch; languishes in heat; is a favorite food of grubs

2. Fine-Leaf Fescue

This group includes several distinct species, all with thin-blade, wispy appearances. These grasses are problem-solvers; they're often added to seed mixes to give lawns more adaptability to shade and drought, and they're low-maintenance.

Pros: Needs little maintenance; tolerates drought and shade

Cons: Less attractive than most lawn grasses

3. Tall Fescue

Tall fescue exhibits good heat and drought tolerance, so it's used a great deal in the Transition Zone and even in the South. Some deem its coarser texture unattractive, but new varieties are nicer.

Pros: Not prone to thatch; tolerant of drought and heat; good pest tolerance

Cons: Doesn't spread into bare areas (except a few new varieties that spread modestly)

4. Perennial Ryegrass

This type of grass is a dark-color, fine-textured species that can be used alone in lawns but is more typically combined with Kentucky bluegrass. It's also used extensively to overseed dormant southern Bermudagrass for winter greenery.

Pros: Among the most attractive grasses; tolerates traffic well; germinates and establishes very quickly

Cons: Doesn't spread, so it won't fill in bare spots on its own

Warm-Season Types of Grass

Warm-season grasses love heat and are well-suited to the hot summers of the South and Southwest. In areas with little summer rain, they go dormant without supplemental water. With a few exceptions, warm-season grasses are not very cold-tolerant, and most undergo winter dormancy. Many varieties are unavailable as seed and must be planted as sprigs or sod.

1. Bermudagrass

"Common" Bermudagrass is coarse, while hybrid varieties offer much finer texture and a more attractive lawn. The former can be planted from seed, while the latter requires sprigs. Some varieties are hardy as far north as Zone 6. In the South and West, dormant Bermudagrass lawns are often overseeded with ryegrass in the fall for winter color.

Pros: Vigorous spreader, quickly recovers from wear; hybrid types exhibit extremely fine texture

Cons: Intolerant of shade; prone to thatch; invades beds

2. St. Augustinegrass

St. Augustinegrass forms a coarse-textured, lush, thick lawn. This type of grass is the most commonly used lawn grass in the Gulf states, but its reliance on summer water and modest cold tolerance limits its use elsewhere.

Pros: Requires only moderate maintenance for a nice lawn; reasonably tolerant of shade

Cons: Susceptible to chinch bugs; does not survive dry summers without supplemental watering

3. Zoysiagrass

Zoysiagrass forms a dense, medium-textured turf and is winter hardy to Zone 6.

Pros: Forms a thick lawn effective at choking out weeds; somewhat tolerant of shade; drought-tolerant.

Cons: Long dormancy; requires annual dethatching or scalping to reduce thatch; slow to establish and recover from wear; not well-suited to winter overseeding

4. Buffalograss

Buffalograss is a type of grass best used on low-maintenance sites. It has a gray-green color and fine texture. Though technically a warm-season grass, buffalograss survives in most of the United States and southern Canada.

Pros: Tolerates climatic extremes; requires little fertilizer, pest control, or mowing

Cons: Has a relatively unattractive color; does not tolerate traffic well; slow to establish; goes dormant in winter, as well as summer (if not irrigated), and thus can be brown for much of the year

5. Centipedegrass

Well-adapted to the Southeast, this "lazy man's grass" forms a coarse, light-to-medium green lawn that looks good with only moderate maintenance. It doesn't have a true winter dormant state. Common centipedegrass is usually used; name varieties are seldom sold.

Pros: Needs little maintenance; invites few serious pest or disease problems; grows slowly for reduced mowing

Cons: Recovers slowly from wear; is easily injured by freezing weather

When to Use Sod, Seed, or Sprigs

Homeowners can establish new lawns with sod or seed (or sprigs or plugs, if seed is not an option). Sod is the quickest way to establish your lawn, but it's also more expensive than the alternatives. Further, you're limited to the varieties that local sod growers have chosen to plant. One situation may demand sod: steep slopes. Slopes are prone to erosion, and heavy rains can wash away seeds; sod will stay put, especially when pinned.

Seed saves you money upfront, and you may find a wider selection of varieties in garden centers. However, lawn planted from seed may take a year to develop a thick strand, and you may find yourself reseeding areas that didn't establish well. Also, weeds may be problematic until the young grass thickens.

Many warm-season types of grass aren't available from seed, so they are sold as sprigs (stolons) or plugs. These are planted in the soil and gradually spread until they've filled in to form a solid lawn. Sprigs are sold by the bushel from garden centers; plugs are sold by the tray.
