Current month

June in Mississippi

Peak humid heat and growth. Feed, mow often, water in the morning, and watch for dollar spot and chinch bugs.

  • Mow: Mow frequently

    Warm-season grass grows fast in Mississippi's June heat. Keep up and never remove more than a third of the blade at once.

  • Water: Deep morning watering

    Water 1 inch per week in the early morning so blades dry by midday — critical in Mississippi's high humidity to dodge fungal disease.

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.

  • Cleanup: Clean up and dethatch

    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.

  • Weed Control: Watch for spring large patch

    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.

  • Mow: Mow low for Bermuda

    Bermuda looks best mowed low and often, around 1–1.5 inches. Centipede and St. Augustine want a higher cut.

July

Active

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.

  • Weed Control: Watch for large patch

    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.

December

Rest

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.

Mississippi Lawn Care FAQs

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.
