Arkansas Lawn Care: What to Plant and When to Feed It

If your grass thins out every summer no matter how much you water it, the problem isn’t drought — it’s that it’s the wrong kind of grass for this climate. Bermudagrass, Zoysiagrass, and St. Augustinegrass are built for the long, hot stretches and mild winters typical here, while fescue and bluegrass simply burn out once the heat sets in. Before you plant anything, figure out how much sun and shade your yard actually gets through the day, since that’s what decides which of the warm-season grasses will hold up in it.

Which grass belongs in Arkansas

Arkansas sits solidly in warm-season turf country. NOAA’s 1991-2020 climate normals for the Little Rock station count 69.2 days a year at or above 90°F, and put the coldest month’s average low at 31.2°F. That combination of long, hot stretches and a mild winter minimum is exactly the profile Clemson Cooperative Extension’s HGIC 1214 fact sheet uses to separate warm-season species from cool-season ones: enough heat to burn out fescue and bluegrass by midsummer, and not enough sustained cold to threaten a warm-season lawn through winter.

That rules out the grasses gardeners moving from a cooler climate are used to. Delaware Lawn Care: What to Plant and When to Feed It covers a state where tall fescue and Kentucky bluegrass hold up fine, because summers there rarely stack up the kind of heat Little Rock logs every year. Plant either one in Arkansas and it thins out and dies back the first heavy summer no matter how well it’s fed or watered — once you’ve settled on the right warm-season species, the Arkansas lawn Calendar lays out when to plant, feed, and mow it through the year.

Clemson’s warm-season list for this climate includes Bahiagrass, Bermudagrass, Carpetgrass, Centipedegrass, Seashore Paspalum, St. Augustinegrass and Zoysiagrass. All of them tolerate the heat this state logs every summer and go dormant, rather than die, through a typical winter here. For a closer look at how these options stack up locally, see this breakdown of Arkansas lawn Best grass.

Bermudagrass is the default pick for open, sunny yards that take heavy foot traffic, since it recovers fastest from wear. Zoysiagrass costs more up front but holds a denser, weed-resistant stand once established. St. Augustinegrass is the one to reach for under trees, since it takes more shade than Bermuda without thinning out. None of these figures come from a single town, either. Little Rock is the reference point here, and a yard in the Ozarks or deep in the Delta can run a season ahead or behind it, so treat these numbers as a starting point, not a guarantee for a specific address.

When to seed or sod here

Warm-season grasses go into the ground in May, once soil has warmed enough for roots to establish quickly. Clemson Cooperative Extension’s HGIC 1203 fact sheet sets that as the general planting window for species like Bermudagrass and Zoysiagrass. That timing already sits well clear of frost risk in this area. The National Weather Service’s Little Rock office puts the last light freeze, the 36°F threshold that matters for tender plants, at April 3, so a May planting date leaves a comfortable margin even after a cool spring.

Cool-season grasses work the opposite half of the year, going into the ground in fall so roots establish before summer heat returns. Minnesota Lawn Care: What to Plant and When to Feed It is built around exactly that fall window, because a cool-season lawn is what that state’s climate actually supports. None of that timing applies to a lawn here. Since every species suited to Arkansas is warm-season, the fall seeding date used for fescue or bluegrass simply isn’t a decision an Arkansas homeowner needs to make.

What moves the May date around locally: a late cold snap, ground still too wet to till, or a sod farm without stock ready yet. Sod can generally go down anytime the soil can be worked from spring through late summer, since it arrives with roots already established. Seed needs a longer runway. NOAA’s 1991-2020 climate normals put the first fall freeze (32°F) at the Little Rock-area station somewhere between November 7 and November 20, so seed sown in May gets five to six months to root before the ground cools, while anything sown in August or later risks heading into winter without enough root mass to survive it.

The feeding calendar that fits this climate

Nitrogen goes down when the grass is actively growing, not on a fixed date circled on a calendar. For the warm-season species this state is built around, that active growth runs from late spring through summer, once the lawn has fully greened up rather than the moment it first breaks winter dormancy. Feed a Bermudagrass or Zoysiagrass lawn too early, while it’s still transitioning out of dormancy, and the nitrogen either leaches away before roots can use it or pushes weak growth that a late cold spell can still damage.

Clemson Cooperative Extension publishes a separate maintenance calendar for each species, and the exact rate, in pounds of actual nitrogen per 1,000 square feet, differs by grass and by month. The Bermudagrass maintenance calendar (HGIC 1216) lays out a full-season schedule for a fast grower that can carry more feedings. The Zoysiagrass calendar (HGIC 1217) sets a lighter load, since Zoysia grows more slowly and doesn’t need as much nitrogen to stay dense. The Centipedegrass calendar (HGIC 1215) recommends the lightest rate of the group, and overfeeding is one of the more common ways home gardeners kill a Centipede lawn outright. The St. Augustinegrass calendar (HGIC 1218) sits in between.

Match the calendar to the grass actually growing in the yard before buying a bag of fertilizer, since a Bermudagrass rate applied to Centipedegrass will do more harm than a season of no feeding at all. A soil test should decide phosphorus and potassium separately from the nitrogen schedule, since most Arkansas soils don’t need extra phosphorus and an unnecessary application just runs off with the next heavy rain.

Mowing height and watering here

Mowing height depends on which warm-season species is actually growing, and the exact figure on that grass’s Clemson maintenance calendar beats any single number applied statewide. Common Bermudagrass is generally kept low, hybrid types even lower. Zoysiagrass runs a bit taller. St. Augustinegrass needs to stay taller still, since it relies on a wider blade to photosynthesize and scalps easily if cut too short. Centipedegrass sits closer to Bermuda’s range and slower besides. Whatever the number for a given lawn, the one-third rule holds across all of them: never remove more than a third of the blade in a single pass, or the grass spends its energy on recovery instead of root growth.

Watering by the numbers

An inch of water a week, from rain and irrigation combined, is the starting figure most warm-season lawns are built around. Arkansas summers push past that on the hottest stretches. NOAA’s Little Rock normals record 69.2 days a year at or above 90°F, and turf loses water faster on those days than a once-a-week schedule replaces it. Sandy soil drains quickly and needs shorter, more frequent watering to avoid runoff, while heavier clay holds moisture longer and can go with less frequent, deeper watering instead.

Humidity slows evaporation but doesn’t cancel out the heat. A lawn watered in late afternoon on a humid day stays wet well into the evening, which is exactly the setup a fungal disease needs to take hold. Morning watering, finished before the heat of the day builds, gives grass blades time to dry out before nightfall arrives.

What goes wrong on lawns in Arkansas

The failures that show up here follow the same humid-summer, mild-winter pattern that decided which grass to plant in the first place.

A wet, humid stretch in summer is brown patch weather, a fungal disease that shows up as roughly circular dead-looking patches in St. Augustinegrass and other warm-season lawns during warm, damp conditions. Common signs include:

• A ring-shaped patch of thinned or matted grass, sometimes with a darker border
• Blades that pull away from the sheath easily and look rotted at the base
• Patches that expand fastest in humid, still air with little wind

It’s rarely fatal on its own, since it damages top growth rather than the crown, but a lawn that gets it every year needs a change to the watering schedule or drainage, not just another round of fungicide.

A hot, dry stretch produces the opposite-looking problem: a lawn that turns brown and crisp but isn’t dead. Warm-season grasses go dormant under drought stress the same way they go dormant after frost, shutting down top growth to protect the crown and roots underneath. Tugging on a few blades to check for a pale but intact base, rather than a rotted one, saves a lot of lawns that would otherwise get torn out and resodded for nothing.

A mild winter, meanwhile, means the weeds never fully quit. Warm-season turf goes dormant and stops competing for space, but cool-season weeds like henbit and chickweed keep growing right through a winter that doesn’t stay consistently cold, then set seed before the lawn wakes up in spring. A pre-emergent applied while the lawn is still dormant is the more common fix, timed to the weed’s cycle rather than the grass’s.

Local help

A county extension office can run a soil test and say exactly what a specific yard needs before a single bag gets bought. The University of Arkansas System Division of Agriculture’s Cooperative Extension Service is the place to start, and its county agents can also confirm which warm-season species performs best in a given area, since conditions in the Ozarks or the Delta can run well ahead of or behind the Little Rock figures used throughout this page.

Common questions

Can I mix warm-season and cool-season grass in the same Arkansas lawn?

Not successfully in most of the state. The cool-season half will thin out and largely die back every summer once temperatures push past 90°F on the schedule NOAA’s Little Rock normals show, so a mixed lawn just means reseeding the cool-season patch every fall indefinitely.

What’s the earliest I can lay sod in spring?

Sod can go down earlier than seed since it arrives with roots already established, but growth stays slow until soil actually warms. Clemson’s HGIC 1203 guidance points to May as the general window, and laying sod a few weeks ahead of that mainly means waiting longer for it to knit into the yard rather than risking cold damage.

Why did my new Zoysiagrass sod turn yellow after I fed it?

Zoysiagrass is slower to take up nitrogen than Bermudagrass, and feeding it before it’s fully greened up for the season can leave it pale or yellow for weeks rather than pushing new growth. Waiting for full green-up before the first feeding, and using a lighter rate than a Bermuda lawn would get, usually fixes it the next season.

Does shade change the mowing height for my grass?

Yes, shaded turf generally needs to be kept toward the taller end of whatever range its species calendar recommends, since more leaf surface helps it capture the limited light it’s getting. A shaded St. Augustinegrass or Zoysiagrass lawn cut to the same height as a sunny one nearby tends to thin out faster.

How do I know if my lawn is dead or just dormant?

Dormant grass has crowns and roots that are still alive even though the top growth looks brown and crisp. Digging up a small plug and checking for white, firm tissue at the base, rather than dark, mushy tissue, is a better test than waiting out an entire season to see if it greens back up on its own.
