Where we are

North Alabama sits in the transition zone

Our summers are hot enough to stress cool-season grasses and our winters are cold enough to stress warm-season ones. Nothing grown here is perfectly at home, which is why there is no single right answer for every lawn in the county.

Further south, the answer is straightforward: warm-season grass, every time. Further north it is equally straightforward the other way. Marshall County is in the band where both kinds are grown, both kinds are sold, and both kinds have a bad month somewhere in the year.

The pattern that works most often here is warm-season grass in the open sun and cool-season grass where there is real shade. That is not a compromise so much as playing to the strengths of each: Bermuda and zoysia want the heat and the light, and tall fescue will hold in places where they simply will not.

It also means that a lawn which looks wrong in February and a lawn which looks wrong in August may both be perfectly healthy. Knowing which grass you have tells you which of those to expect.

Identification

Telling them apart without a lab

Blade width and how the plant spreads will get you to the right answer nearly every time. Look at a single plant rather than at the lawn from the kitchen window.

Start with how it spreads. Bermuda runs aggressively, both above ground and below, and will be found creeping into a bed or across the edge of a drive. Zoysia runs too but far more slowly. Centipede runs above ground only, in obvious visible strands. St. Augustine runs in thick above-ground stems you can pick up in your hand. Tall fescue does not run at all - it grows in clumps, and that alone identifies it.

Then look at the blade. Bermuda is fine and pointed. Zoysia is fine to medium and stiff, almost bristly underfoot, and it is the one that feels springy to walk on. Centipede is a noticeably lighter apple green with a coarser blade. St. Augustine has by far the widest blade of the five, with a blunt, folded, boat-shaped tip.

Color in winter is the last confirmation. Bermuda, zoysia, centipede and St. Augustine all go tan or straw colored once the soil cools. Tall fescue stays green through a normal North Alabama winter. A lawn that is green in January is almost certainly fescue, or ryegrass that somebody overseeded.

Grass	Blade	Spreads by	Winter color
Bermuda	Fine, pointed	Runners above and below ground, fast	Tan, dormant
Zoysia	Fine to medium, stiff	Runners, slowly	Tan, dormant
Centipede	Coarse, light apple green	Above-ground runners, slowly	Tan, dormant
St. Augustine	Widest, folded boat tip	Thick above-ground stems	Tan, dormant
Tall fescue	Broad, ridged, dull green	Does not run - grows in clumps	Stays green

A photograph in good light usually settles an identification. It is also the first thing a crew does on an estimate visit, because mowing height, feeding and weed timing all follow from the answer.

Choosing

What each one is actually good at

Every one of these is the right answer somewhere. The question is never which grass is best, it is which one suits this property.

Bermuda

Full sun, heavy use, fast repair. The toughest of the five for a yard that gets played on, and the quickest to close a worn patch. It wants regular mowing and it will not tolerate shade.

Zoysia

A dense, even, springy turf that needs mowing less often than Bermuda and takes light shade better. The trade is repair speed: damage takes a season to close rather than weeks.

Centipede

The low-input option. Less feeding than anything else here, prefers acid soil, stays a lighter green. Its weakness is cold, and we are near the northern edge of where it is comfortable.

St. Augustine

The most shade tolerant of the warm-season grasses, and the most cold sensitive. It grows here and it does get winter injury here, which is the trade being made.

Tall fescue

The shade answer, and the one that stays green in winter. It struggles through the hottest weeks and it does not fill its own gaps, so fall overseeding is part of owning it.

A mixture

Common by accident, rarely tidy on purpose. Different colors, textures, mowing heights and dormancy dates mean a mixed lawn looks patchy exactly when you want it to look best.

The usual questions

Sun, shade, children and dogs

Four questions come up more than all the others put together, and they have short answers.

Drought tolerance follows roughly the same order as heat tolerance. Bermuda and zoysia will go dormant and brown rather than die, and green back up when water returns. Tall fescue has the least tolerance of the five and is usually the first thing to thin out in a hot, dry July. That is covered in the drought and dormancy guide.

Full sun and hard use: Bermuda. Nothing else grown here repairs as fast.
Real shade: tall fescue first, St. Augustine next among the warm-season options. Below about four hours of direct sun a day, no grass will hold reliably and a bed is the honest answer.
Children and traffic: Bermuda, for the repair speed rather than the feel. Zoysia makes a nicer cushion but a worn track takes far longer to close.
Dogs: Bermuda again, for the same reason. Urine spots are a separate problem from the grass choice and are covered in the pets and children guide.

Starting a lawn

Seed, sod, plugs or sprigs

Not every grass is available every way. That practical fact narrows the choice more often than preference does.

Sod gives an instant lawn and it is the only option for grasses that are not sold as seed, which includes most zoysia and St. Augustine. Seed is far cheaper and is the normal route for tall fescue and for common Bermuda. Plugs and sprigs sit in between - cheaper than sod, slower to cover, and dependent on good weed control while the gaps close.

Timing is not optional. Warm-season sod goes down while the soil is warm and the grass is growing, which here is late spring through summer. Tall fescue is seeded in fall, so it has a winter and a spring to establish before it meets its first Alabama summer. The new sod and seed guide covers both.

Answers

Questions about grass types guide

What grass grows best in Marshall County?

Bermuda and zoysia in full sun, tall fescue where there is real shade, centipede on low-input lawns with acid soil. St. Augustine is grown here but is the most cold sensitive of the group.

How can I tell what grass I have?

Look at how it spreads and how wide the blade is. Bermuda runs fast and is fine bladed; zoysia is stiff and springy; centipede is a light apple green; St. Augustine has the widest blade with a folded tip; tall fescue grows in clumps and stays green in winter.

Which grass handles shade best?

Tall fescue takes the most shade of the grasses grown here, with St. Augustine next among the warm-season options. Below about four hours of sun a day, a mulched bed is a better answer than any grass.

What is the difference between Bermuda and zoysia?

Bermuda grows fast, repairs fast, needs full sun and needs mowing often. Zoysia grows slowly, makes a denser turf, takes light shade better and needs mowing less often, but damage takes far longer to close up.

Why does my lawn go brown every winter?

Dormancy, and it is normal. All four warm-season grasses grown here stop growing and go tan once the soil cools, then green back up in spring. Dormancy is even across the whole lawn; damage has edges.

Can HRH identify my grass?

Yes. It is the first thing a crew does on an estimate visit, because mowing height, feeding and weed timing all follow from it. Estimates are free.

Not sure what your property needs?

Call and ask. We would rather come and look at it than guess over the phone, and it does not cost you anything either way.
