How to use this calendar
Start with seed type, then trust the soil
State timing is useful because frost, rainfall, soil texture, and heat stress change the risk profile. It is still a filter, not a guarantee. Confirm the grass species, soil temperature, and watering plan before you spread seed.
Local constraints
- Transition zone — warm and cool-season both struggle
- Heavy Delta clay
- Humid summers with constant fungal pressure
- Bermuda invasion of fescue lawns
- Armyworms in fall
- Ice storms in northern AR
Warm grass
Bermuda and zoysia wait for spring heat
Warm-season seed needs warmer soil. The same state can have two correct windows depending on grass type.
Seasonal plan
Season-by-season planting plan for Arkansas
Use the Arkansas calendar as a timing sequence: prep before the window, seed when soil temperature is right, and protect new turf through the first stress season.

50 to 70F soil
March - May
Spring
- 1Apply pre-emergent herbicide when soil temps reach 55 degrees at 4-inch depth — typically early to mid-March in south Arkansas, late March in the Ozarks (the U of A Extension tracks soil temps by region)
- 2Scalp dormant bermuda lawns in late March to early April once you see 50% green-up — cut to 0.5 to 0.75 inches and bag all clippings to expose soil to sunlight
- 3Core aerate bermuda lawns in mid-April once full green-up is underway — this is especially critical on Delta clay and Central Arkansas red clay soils
- 4Seed bermuda or centipede in late April through May once soil temps hold above 65 degrees — the warm soil and spring rains create ideal germination conditions
- 5Begin mowing bermuda at 1.5 to 2 inches once active growth resumes — mow at least weekly to prevent the grass from getting ahead of you in the rapid spring growth flush
- 6Apply a balanced fertilizer (15-5-10) in mid to late April after full green-up — never fertilize dormant or semi-dormant warm-season turf
June - August
Summer
- 1Water deeply and infrequently — deliver 1 to 1.5 inches per week in one or two early-morning sessions, adjusting for rainfall (Arkansas gets enough summer thunderstorms that you may not need to irrigate every week)
- 2Scout for armyworms beginning in late July — while the big wave usually hits in September/October, early-season populations can appear in hot years
- 3Maintain bermuda mowing height at 1.5 to 2 inches and mow every 5 to 7 days — the humidity-driven growth rate in Arkansas means bermuda can get away from you fast
- 4Apply a light fertilizer application (0.5 lb nitrogen per 1,000 sq ft) in June — avoid nitrogen after July 4th to reduce disease pressure during peak humidity
- 5Monitor fescue lawns in the Ozarks for summer stress — raise mowing height to 4 inches, water 1.5 inches per week, and accept that some browning is normal in July and August
- 6Treat fire ant mounds as they appear — broadcast bait products are most effective when applied in early morning or late evening when ants are actively foraging
September - November
Fall
- 1Overseed fescue lawns in the Ozarks by mid-September through early October — this is the single most important maintenance event for cool-season lawns in Arkansas
- 2Scout aggressively for armyworms from late September through mid-October — check the lawn at dusk when they're most active, and treat immediately with bifenthrin or spinosad if you find them
- 3Apply a second round of pre-emergent in early September to block winter annual weeds like henbit and annual bluegrass
- 4Core aerate bermuda lawns one final time in September while the grass is still actively growing and can heal the plug holes
- 5Apply a winterizer fertilizer (high potassium, such as 5-5-15) in mid to late October to improve cold hardiness before dormancy
- 6Continue mowing bermuda until growth stops — do not scalp going into winter, as the leaf blade insulates the crown from freeze damage
December - February
Winter
- 1Leave dormant bermuda alone — no fertilizer, no water (unless you go 6-plus weeks without precipitation), no mowing
- 2Spot-treat winter weeds like henbit, chickweed, and annual bluegrass with a post-emergent herbicide while the lawn is dormant and weeds are actively growing
- 3Soil test in January or February through the U of A Cooperative Extension Service — results take 2 to 3 weeks, and you want recommendations in hand before spring
- 4Sharpen mower blades and service irrigation systems during the off-season — dull blades tear grass and create entry points for disease
- 5Plan renovation projects: drainage improvements, soil amendment, and grading work are best done in the dormant season before spring growth begins
- 6Order grass seed by late January — improved bermuda and transition zone blends sell out quickly as spring approaches
Regional timing notes
Arkansas is not one planting zone
Use these regional notes to adjust the statewide window for elevation, soil, heat, irrigation pressure, and local grass type.
Northwest Arkansas / Ozarks
The booming Northwest Arkansas corridor — Fayetteville, Bentonville, Rogers, Springdale — sits in the Ozark Plateau at elevations ranging from 1,000 to 2,500 feet. The soil is thin, rocky, and cherty, with fractured limestone underneath and a slightly acidic to neutral pH of 5.5 to 7.0. Winters are colder here than anywhere else in the state (Zone 7a), with regular freezes, occasional ice storms, and snow that can linger for days. This is the only part of Arkansas where tall fescue can be grown as a primary lawn grass with reasonable success. The rocky soil drains fast, which helps fescue survive summer but means you need to water more frequently during dry spells. Bermuda can work in full-sun areas but goes dormant early and greens up late compared to the rest of the state.
- Overseed fescue lawns every September — the rocky Ozark soil and summer heat thin fescue stands annually, and fall overseeding is non-negotiable to maintain density
- Soil depth varies wildly even within a single lot — probe before seeding and add 2 to 3 inches of topsoil over rocky shallow areas for better root establishment
Central Arkansas / Little Rock Metro
The Little Rock metro and surrounding counties sit right at the dividing line between Ozark foothills and Gulf Coastal Plain, making it the epicenter of Arkansas's transition zone challenge. The soil is a mix of red clay, sandy loam, and river bottom alluvium depending on your exact location — neighborhoods in west Little Rock have completely different soil than properties in North Little Rock or Jacksonville. Zone 7b/8a conditions mean long, hot, humid summers and mild-to-moderate winters with occasional hard freezes. Bermuda is the dominant lawn grass across the metro, but you'll see fescue holding on in shaded areas and north-facing slopes, especially in older Hillcrest and Pleasant Valley neighborhoods with mature hardwood canopy.
- The red clay around west Little Rock compacts severely — core aerate in April and again in September to maintain root health
- Bermuda-fescue blends can work in Little Rock but require constant management — the bermuda will aggressively invade fescue areas every summer, and you'll spend fall trying to re-establish the fescue
Arkansas Delta / East Arkansas
East of Crowley's Ridge, the Arkansas Delta stretches flat and fertile from Jonesboro down through West Memphis, Helena, and Pine Bluff. This is Mississippi River alluvial clay — heavy, dark, incredibly productive agricultural soil that is brutally difficult to manage as a home lawn. Drainage is poor, the soil stays waterlogged for days after rain, and the clay compacts into something resembling pottery when it dries. The region is Zone 8a with long, hot, deeply humid summers that push bermuda to its limits through sheer moisture overload. Fungal diseases thrive in the saturated conditions. But bermuda is still the clear winner here — its aggressive growth habit and heat tolerance make it the only grass that consistently performs in Delta conditions. Centipede grass also has a following in the southern Delta around Pine Bluff and Monticello where the sandy Coastal Plain soils begin to mix with the clay.
- Drainage is your number one priority on Delta clay — grade your lot to move water away from the lawn, and consider French drains if water stands for more than 24 hours after rain
- Core aerate Delta clay every spring and fall without exception — the heavy soil seals shut within weeks and suffocates bermuda roots
South Arkansas / Timberlands
South Arkansas from Texarkana through El Dorado and down to the Louisiana border is pine timber country, with sandy Coastal Plain soils, heavy shade from loblolly and shortleaf pines, and a subtropical climate that puts it firmly in Zone 8a/8b. The soil is a dramatic departure from the rest of the state — sandy, acidic (pH 5.0 to 6.0), and well-drained, almost the exact opposite of the Delta clay just to the east. Annual rainfall exceeds 50 inches, and the humidity is relentless. Bermuda performs well in full-sun areas, but the pine canopy across much of the region creates shade challenges that push homeowners toward centipede or zoysia. Centipede grass is genuinely well-suited here — the acidic sandy soil is exactly what it prefers, and it handles the partial shade under pine canopy better than bermuda.
- Centipede grass thrives in south Arkansas's acidic sandy soil — don't lime unless your pH drops below 5.0, as centipede actually prefers slightly acidic conditions
- Rake pine straw off the lawn regularly — while a thin layer is fine, heavy accumulations smother grass and create fungal breeding grounds
