Current month
Warm-season grass thrives in the heat; Ozark fescue goes into survival mode. Raise the fescue mower, water deep.
Mow: Mow to the grass
Bermuda low and frequent; centipede high. Raise fescue to 3.5–4 inches to survive the heat.
Water: Morning deep watering
Water 1 inch per week in the early morning so blades dry by midday. Warm-season grass needs less than the struggling fescue.
Rain Bird ESP-TM2 Smart Irrigation Controller (8-Zone) →Arkansas sits in the warm half of the transition zone, where the heat tilts most lawns toward warm-season grass but the cooler Ozarks still support cool-season fescue. Bermuda dominates sunny Arkansas lawns, with zoysia for a denser look, centipede on the acidic, sandy soils of the south, and turf-type tall fescue common in the shadier and higher Ozark and Ouachita country. The grass you grow flips the entire calendar, so know it first.
For the warm-season majority — Bermuda, zoysia, centipede — the calendar runs the Southern way: a late-winter pre-emergent before green-up, a spring scalp to clear the dead canopy, heavy feeding and mowing through the long, hot, humid summer, and a stop on nitrogen by late summer so the grass isn't pushing tender growth into frost. Arkansas's humidity drives large patch in spring and fall and dollar spot in summer, and centipede on southern soils needs a light hand to avoid 'centipede decline.'
For Ozark fescue lawns, the calendar inverts to cool-season: spring pre-emergent and light feeding, a survival summer where the heat thins the fescue, and a critical fall recovery seeding to rebuild it. Arkansas summers are hard on fescue, so that September overseed is essential every year. Whichever grass you have, time the work to its dormancy and the soil temperature, and stay ahead of the humidity-driven disease.
Spring pre-emergent
Late February – March
Warm soil germinates crabgrass early. Apply before warm-season green-up and before soil hits 55°F.
Warm-season green-up + scalp
April
Scalp Bermuda and zoysia low to clear the dead winter canopy as they break dormancy.
Warm-season feeding stops
Late August
Stop nitrogen so warm-season grass isn't pushing tender growth into frost.
Fescue fall recovery seeding
September – October
The make-or-break window for Ozark cool-season lawns cooked by summer.
Spring
Warm-season: pre-emergent before green-up, then scalp low and begin feeding once active. Fescue: pre-emergent, light feeding, mow tall.
Summer
Warm-season grass is in its prime — feed, mow, scout pests, water in the morning. Ozark fescue is in survival mode — mow high, water deep.
Fall
Warm-season grass winds down — stop feeding, apply fall pre-emergent, watch large patch. Fescue's main season — aerate, overseed, feed.
Winter
Warm-season grass is dormant and tan; control winter weeds. Ozark fescue stays green and slow.
Warm-season grass is dormant and tan; Ozark fescue stays green. Control winter weeds.
Weed Control: Spot winter weeds
Poa annua and henbit show up green against the dormant warm-season lawn. Spot-treat now while they're easy to see.
Warm-season grass still dormant; soil warming in the south. Plan the pre-emergent and a soil test.
Soil Test: Pull a soil test
Arkansas soils range from acidic sand in the south to clay in the delta. A test through the U of A Extension matters — especially for centipede, easily harmed by the wrong lime.
Apply the spring pre-emergent as the soil warms, before warm-season green-up. Fescue is in peak spring growth.
Pre-Emergent: Apply crabgrass pre-emergent
Warm soil germinates crabgrass early in Arkansas. Apply before warm-season green-up and before soil hits 55°F. A split application carries the long season.
Scotts Turf Builder EdgeGuard DLX Broadcast Spreader →Cleanup: Clean up and dethatch
Rake out winter debris and dethatch warm-season lawns lightly just before green-up.
Warm-season green-up — scalp Bermuda and zoysia low. Fescue's spring window is closing as heat builds.
Mow: Scalp warm-season lawns
As Bermuda and zoysia green up, drop the mower one to two notches and bag the clippings to clear the dead canopy. Don't scalp centipede or fescue.
Toro Recycler 22" SmartStow Self-Propelled Mower →Fertilize: Light feeding for fescue
A modest spring feeding for Ozark fescue. Hold off feeding warm-season grass until it's fully active in May.
Scotts Turf Builder EdgeGuard DLX Broadcast Spreader →Warm-season grass hits full stride — begin feeding (lightly on centipede). Fescue's spring window closes.
Fertilize: Begin warm-season feeding
Bermuda and zoysia are growing hard and ready for nitrogen. Centipede wants only a fraction as much, or it declines.
Scotts Turf Builder EdgeGuard DLX Broadcast Spreader →Edge: Edge and clean up beds
Everything is growing hard. Keep edges crisp along drives and beds.
Worx WG896 12-Amp Electric Lawn Edger & Trencher →Warm-season grass thrives in the heat; Ozark fescue goes into survival mode. Raise the fescue mower, water deep.
Mow: Mow to the grass
Bermuda low and frequent; centipede high. Raise fescue to 3.5–4 inches to survive the heat.
Water: Morning deep watering
Water 1 inch per week in the early morning so blades dry by midday. Warm-season grass needs less than the struggling fescue.
Rain Bird ESP-TM2 Smart Irrigation Controller (8-Zone) →Peak heat and humidity. Warm-season grass is in its glory; fescue hangs on. Feed warm-season, scout pests.
Fertilize: Feed warm-season grass
Keep nitrogen coming to Bermuda and zoysia through the heat. Do NOT feed stressed Ozark fescue in July.
Weed Control: Scout for dollar spot and pests
Dollar spot leaves straw-colored patches in summer; scout weekly. Keep the blade sharp to limit disease in the humidity.
Stop feeding warm-season grass by month's end. Begin prepping Ozark fescue for the fall recovery seeding.
Fertilize: Last warm-season feeding
Stop feeding Bermuda, zoysia, and centipede by late August. Late nitrogen pushes tender growth the first frost will burn.
Aerate: Aerate fescue lawns
Core-aerate Ozark fescue lawns to relieve summer compaction ahead of the fall overseed.
Fescue's most important month — overseed the summer damage and feed. Warm-season grass winds down; apply fall pre-emergent.
Overseed: Fescue fall recovery seeding
The make-or-break window for Ozark fescue. Overseed everything the summer thinned with a heat-tolerant turf-type tall fescue blend.
Barenbrug RTF Water Saver →Pre-Emergent: Fall pre-emergent (warm-season lawns)
On warm-season lawns, apply a fall pre-emergent to suppress Poa annua. Skip it where you've just overseeded fescue.
Scotts Turf Builder EdgeGuard DLX Broadcast Spreader →Fescue fills back in. Warm-season grass slows toward dormancy. Keep mowing fescue and watch for large patch.
Mow: Keep mowing fescue
Ozark fescue keeps growing through the mild fall. Hold it around 3 inches. Warm-season grass slows down.
Weed Control: Watch for large patch
Cooling, wet nights trigger large patch in zoysia and centipede. Reduce evening watering to slow it.
Warm-season grass goes dormant and tan. Fescue stays green. Final cleanup and a last meaningful mow.
Cleanup: Clear leaves off both lawn types
Keep leaves off new fall fescue and off dormant warm-season turf alike — leaf mats smother both.
Greenworks Pro 80V 730 CFM Brushless Leaf Blower (BL80L2512) →Warm-season grass is dormant; fescue green but slow. Control winter weeds and winterize equipment.
Weed Control: Control winter weeds
Spot-treat henbit, chickweed, and Poa annua, which stand out green against dormant warm-season turf. Winterize the mower.

Buyers who want maximum CFM-per-dollar in a serious residential blower and don't need the bigger EGO ecosystem.
It depends where you are. Most of Arkansas tilts warm-season — Bermuda on sunny lawns, zoysia for density, centipede on the acidic sandy soils of the south. But in the cooler, higher Ozarks and Ouachitas, cool-season tall fescue is common because the summers are a bit more forgiving. Your entire lawn calendar depends on which type you grow, so identify it first.
In April, as the Bermuda or zoysia breaks dormancy and greens up. Drop the mower one or two notches and bag the clippings to clear the dead brown winter canopy so sunlight reaches the crowns and speeds green-up. Don't scalp centipede or cool-season fescue hard — they don't tolerate it the way Bermuda does.
September into October, in the cooler Ozark and Ouachita country where fescue grows. Arkansas summers thin and cook tall fescue badly, so the fall recovery seeding is essential every year. Aerate first to relieve compaction, then overseed with a heat-tolerant turf-type tall fescue blend and keep the new seed moist until it establishes.
Twice a year for warm-season lawns. Apply a spring pre-emergent in late February through March — before the lawn greens up and before soil hits 55°F — with a second application later for the long season, to stop crabgrass and summer weeds. Then apply a fall pre-emergent in September to suppress Poa annua and other winter weeds in the dormant lawn.
Arkansas is in the transition zone group. These states follow similar seasonal logic, though local soil, elevation, and weather still matter.
