Current month
July in Mississippi
Hot, very humid, and growing hard. Keep feeding and mowing; watch for dollar spot, gray leaf spot, and chinch bugs.
🌱
Fertilize: Continue feeding
Keep nitrogen coming to Bermuda and zoysia through the heat; spoon-feed rather than dumping it. Hold centipede to a light hand.
🌿
Weed Control: Scout for summer disease and pests
Dollar spot and gray leaf spot thrive in the muggy heat; chinch bugs work sunny St. Augustine. Scout weekly, treat only affected zones, and keep the blade sharp.
In Mississippi, the next Saturday job is active warm-season maintenance. Water early, feed only growing turf, and skip cool-season seed unless you are intentionally planning a winter overseed.
Step 1
Lock the early water window
Run irrigation before heat and wind climb, then fix dry edges or overspray before the next mowing cycle bakes the pattern into the lawn.
Mississippi is warm-season lawn country with a long, hot, very humid growing season, and the calendar runs opposite the cool-season North. Centipede is hugely popular here — it's the low-maintenance favorite on Mississippi's acidic, sandy soils — alongside Bermuda on sunny lawns, St. Augustine in shade and along the Gulf Coast, and zoysia for a dense look. All of them go dormant tan over winter and do their growing and feeding from late spring through summer.
Two things define a Mississippi lawn. The first is humidity and disease. The state's muggy, wet summers make it one of the most fungal-disease-prone lawn climates in the country — large patch (brown patch) in spring and fall, plus dollar spot and gray leaf spot in summer. Watering in the early morning, easing off nitrogen at the wrong times, and keeping a sharp blade are the everyday defenses. The second is centipede's special status: it thrives on neglect and the state's acidic soils but is easily killed by over-fertilizing or over-liming — 'centipede decline' is a classic Mississippi mistake.
The calendar inverts the Northern one: a late-winter pre-emergent to stop summer weeds before green-up, a spring scalp to clear the dead canopy, heavy feeding and frequent mowing through the long summer, and a hard stop on nitrogen in early fall so the grass hardens off before frost. Fall pre-emergent handles winter weeds. Time it to the grass's dormancy and the soil temperature, go light on centipede, and stay ahead of the humidity-driven disease.
Key Dates to Hit in Mississippi
Spring pre-emergent
Late February – March
Mississippi's warm soil germinates crabgrass early. Apply before green-up and before soil hits 55°F.
Green-up + scalp
April
Scalp Bermuda and zoysia low to clear the dead winter canopy as they break dormancy.
Feeding season
May – August
Feed warm-season grass through the heat — but very lightly on centipede to avoid decline.
Stop feeding / fall pre-emergent
Late August – September
Stop nitrogen before frost; apply fall pre-emergent and watch for large patch as nights cool.
The Year at a Glance
🌱 Spring
Apply pre-emergent before green-up, then scalp Bermuda and zoysia low. Begin feeding once the grass is fully active, and watch for early large patch.
☀️ Summer
Peak growth in the humid heat. Feed (lightly on centipede), mow often, water in the morning, and stay on top of fungal disease.
🍂 Fall
Stop feeding by early fall. Apply a fall pre-emergent, watch hard for large patch as nights cool, and let the lawn harden off.
❄️ Winter
Dormant and tan. Mow rarely, control winter weeds, and leave the dormant grass alone.
Month-by-Month Calendar
January
Rest
Warm-season grass is dormant and tan statewide. Control winter weeds and plan ahead.
🌿
Weed Control: Spot winter weeds
Poa annua, henbit, and chickweed show up green against the dormant tan lawn. Spot-treat them now while they're easy to see.
February
Light
Still dormant, but the soil is warming, the Gulf Coast first. Plan the pre-emergent and a soil test.
🧪
Soil Test: Pull a soil test
Mississippi soils are often acidic. A test through the MSU Extension is essential — especially for centipede, which is easily harmed by the wrong lime or fertilizer.
March
Active
Apply the spring pre-emergent as the soil warms, before green-up and before summer weeds germinate.
🛡️
Pre-Emergent: Apply crabgrass pre-emergent
Mississippi's warm soil germinates crabgrass early. Apply before green-up and before soil hits 55°F. Plan a second application in 8–10 weeks for the long season.
Rake out winter debris and dethatch lightly just before green-up — warm-season lawns benefit most from it then.
April
Active
Green-up. Scalp Bermuda and zoysia low to clear the dead canopy and watch for early large patch in the warm, wet weather.
✂️
Mow: Scalp Bermuda and zoysia
As they break dormancy, drop the mower one to two notches and bag the clippings to clear the dead brown canopy. Don't scalp centipede or St. Augustine hard.
Warm, wet spring weather triggers large patch as the grass greens up — expanding circular patches in zoysia, centipede, and St. Augustine. Ease off evening watering.
May
Peak
Full growth. Begin the main feeding season — but go very light on centipede. Mow regularly.
🌱
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.
Hot, very humid, and growing hard. Keep feeding and mowing; watch for dollar spot, gray leaf spot, and chinch bugs.
🌱
Fertilize: Continue feeding
Keep nitrogen coming to Bermuda and zoysia through the heat; spoon-feed rather than dumping it. Hold centipede to a light hand.
🌿
Weed Control: Scout for summer disease and pests
Dollar spot and gray leaf spot thrive in the muggy heat; chinch bugs work sunny St. Augustine. Scout weekly, treat only affected zones, and keep the blade sharp.
August
Active
Still hot, humid, and growing. The feeding season winds down — last main feeding late this month.
🌱
Fertilize: Final main feeding
Make your last heavy nitrogen application by late August. Feeding later pushes tender growth that the first frost will burn.
✂️
Mow: Keep mowing with a sharp blade
Stay on the mowing rhythm through the late-summer growth. Torn blades from a dull mower invite disease in the humidity.
September
Active
Growth slows as nights cool. Stop feeding, apply a fall pre-emergent, and watch hard for large patch.
🛡️
Pre-Emergent: Fall pre-emergent for winter weeds
Apply a fall pre-emergent in early-to-mid September to suppress Poa annua and other cool-season weeds before they germinate.
Cooling, wet nights are prime large-patch weather in humid Mississippi. Expanding circular patches mean it's active — reduce evening watering to slow it.
October
Light
The lawn winds down toward dormancy. A potassium-rich product can boost winter hardiness; ease off mowing.
🌱
Fertilize: Optional potassium feeding
A potassium-only application (no nitrogen) improves winter hardiness without pushing tender growth. Skip nitrogen entirely now.
✂️
Mow: Slow the mowing
Growth is slowing. Raise the cut slightly and mow less often as the grass heads toward dormancy.
November
Light
The grass goes dormant and tan, the north first. Final cleanup and last mow.
🍂
Cleanup: Clear leaves off dormant turf
Even dormant warm-season grass suffers under a packed leaf layer. Keep leaves cleared through the drop.
Dormant and tan statewide. Control winter weeds, winterize equipment, and leave the lawn alone.
🌿
Weed Control: Control winter weeds
Henbit, chickweed, and Poa annua stand out green against the dormant lawn. Spot-treat as needed and winterize the mower.

Use the Mississippi calendar to decide timing before you buy.
Start with the state guide. If it says to wait, do not buy starter fertilizer for immediate use; save the remaining links for the next viable warm-season establishment window, then check local fertilizer rules.
1 · Decide timing and seed
Mississippi seed and timing guide
Confirm a viable warm-season establishment window before comparing Bermuda, zoysia, centipede, and other Mississippi options.
Do not apply now. Revisit this only after the state guide confirms an active seeding window, then check the soil test, label, and county fertilizer rules.
The spreaders, controllers, seed, and tools that show up most often in the Mississippi calendar above — built around the green-up push after the last frost — spreaders, irrigation timing, and warm-season seed do the heavy lifting once the lawn wakes up.

Why is my centipede lawn dying in patches in Mississippi?
It's most likely 'centipede decline,' usually caused by too much care. Centipede is adapted to Mississippi's acidic, low-fertility soils and is easily harmed by over-fertilizing, over-liming, or letting thatch build up. Pull a soil test, feed it sparingly, lime only if the test calls for it, and keep thatch down. Treating centipede like Bermuda is the fastest way to thin it out.
How do I prevent lawn disease in Mississippi's humidity?
Mississippi's muggy, wet summers make it one of the most disease-prone lawn climates anywhere — large patch in spring and fall, dollar spot and gray leaf spot in summer. The everyday defenses are watering in the early morning so blades dry by midday, easing off nitrogen at the wrong times, keeping the mower blade sharp, and reducing evening watering when large patch is active. Treat with fungicide only when disease is actively spreading.
When should I fertilize my Mississippi lawn?
From May through late August, while the warm-season grass is actively growing, then stop nitrogen so the lawn isn't pushing tender growth into the first frost. The exception is centipede, which needs only a fraction of what Bermuda or zoysia wants — over-feeding it causes decline. Never fertilize warm-season grass during winter dormancy.
When do I scalp my Bermuda lawn in Mississippi?
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 St. Augustine hard — they don't tolerate it the way Bermuda does.
