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
- Extreme heat and humidity year-round
- Fire ants throughout the state
- Fall armyworm outbreaks
- Heavy clay in the Delta
- Chinch bugs in bermuda lawns
- Hurricane and flooding damage on the Gulf Coast
Avoid
Do not chase early green-up
Warm afternoons can arrive before soil is ready. Early seed often stalls, thins, or loses to weeds.
Seasonal plan
Season-by-season planting plan for Mississippi
Use the Mississippi calendar as a timing sequence: prep before the window, seed when soil temperature is right, and protect new turf through the first stress season.

Warm-season
Warm soil first
65F+ soil
March - May
Spring
- 1Apply pre-emergent herbicide when soil temperatures reach 55 degrees at 4-inch depth — in south Mississippi that's late February, in Jackson early March, in Tupelo mid-March. MSU Extension's soil temperature resources help pinpoint timing
- 2Scalp bermuda lawns to 0.75 inches once 50% green-up is visible — mid-March on the coast, late March in Jackson, mid-April in north Mississippi. Bag all clippings to expose soil to warming sunlight
- 3Begin mowing bermuda at 1 to 1.5 inches once active growth resumes — frequent mowing encourages lateral spread and density
- 4Seed bare spots or establish new bermuda lawns once soil temps hold above 65 degrees for two weeks — late April statewide is the safe window
- 5Apply the first round of fertilizer (16-4-8 or similar) in late April after bermuda is fully green and actively growing — MSU Extension recommends 1 lb of nitrogen per 1,000 sq ft
- 6Broadcast fire ant bait across the entire lawn in April as mound activity increases — baits are more effective than individual mound treatments for area-wide control
June - August
Summer
- 1Maintain bermuda at 1 to 2 inches and mow frequently — in Mississippi's growing season, that means mowing every 4 to 5 days during peak growth in June and July
- 2Water 1 to 1.5 inches per week in one or two deep sessions — morning watering before 8 AM reduces disease risk from extended leaf wetness in Mississippi's humid conditions
- 3Apply second fertilizer round in June (0.5 to 1 lb nitrogen per 1,000 sq ft) using a slow-release formula — avoid quick-release nitrogen in summer heat
- 4Scout for large patch (brown patch) in centipede and zoysia lawns — circular brown areas expanding outward indicate fungal infection, treat with azoxystrobin or propiconazole
- 5Monitor for chinch bugs in July and August, especially in sunny bermuda areas along driveways and sidewalks — treat with bifenthrin at first sign of yellowing
- 6For centipede grass, do NOT over-fertilize in summer — centipede decline is caused by excessive nitrogen. One pound of nitrogen per 1,000 sq ft for the entire year is the MSU Extension maximum for centipede
September - November
Fall
- 1Scout aggressively for fall armyworms in September and October — they can destroy a bermuda lawn in 48 hours. Birds congregating on the lawn and skeletonized leaf blades are early warning signs
- 2Apply a second round of fire ant bait in September when colony activity increases with cooler temperatures and fall rains
- 3Apply winterizer fertilizer (high potassium, 10-5-15 or similar) in early to mid-October — potassium strengthens cell walls and improves cold tolerance, especially critical in north Mississippi
- 4Apply pre-emergent for winter annual weeds (Poa annua, henbit, chickweed) in early October before soil temps drop below 70 degrees
- 5Continue mowing bermuda until growth stops naturally — on the coast that may not be until early December, in north Mississippi growth typically ceases by mid-November
- 6Overseed bermuda with annual ryegrass in October if you want winter color — this is common on the coast and in Jackson but less practical in north Mississippi where the overseed window is short
December - February
Winter
- 1Leave dormant bermuda and zoysia alone — no fertilizer, minimal water (unless you go 6-plus weeks without rain), and no mowing
- 2Spot-treat winter weeds like henbit, chickweed, and annual bluegrass with a post-emergent containing 2,4-D while the lawn is dormant and weeds are actively growing
- 3On the Gulf Coast, bermuda may show partial green-up during warm January spells — do not scalp or fertilize yet, as freeze events are still possible through late February
- 4Submit soil samples to MSU Extension's soil testing lab — winter is the ideal time to test so you have results in hand before the spring growing season begins
- 5Sharpen mower blades and service all equipment during the off-season — Mississippi's long mowing season (8-9 months) puts more wear on equipment than Northern states
- 6Plan any major lawn renovation projects including grading, drainage improvements, and irrigation repairs — complete soil work before bermuda breaks dormancy in March
Regional timing notes
Mississippi is not one planting zone
Use these regional notes to adjust the statewide window for elevation, soil, heat, irrigation pressure, and local grass type.
Mississippi Delta
The Delta is flat, hot, and built on some of the most fertile soil in the world — but that fertility comes in the form of heavy buckshot clay that's a nightmare to manage as a lawn surface. This alluvial floodplain stretching from Tunica County south through Greenville, Cleveland, and Greenwood to Vicksburg has soil with 50 to 60 percent clay content that swells when wet and cracks into hard chunks when dry. Zone 8a conditions mean long, brutal summers with temperatures exceeding 95 degrees for weeks at a stretch and humidity that makes it feel like 110. Bermuda is the dominant grass in the Delta because it handles the heavy clay, the heat, and the periodic flooding from the Mississippi River tributaries that still overflow their banks most springs. The flat terrain means drainage is a constant issue — water has nowhere to go after heavy rains, and low spots can stay waterlogged for days.
- Delta buckshot clay must be core aerated twice annually — April and September — to combat the severe compaction that develops in this heavy soil
- Bermuda is the only grass that handles both the Delta clay and the periodic spring flooding — it recovers from submersion faster than any other warm-season species
Jackson Metro / Central Mississippi
The Jackson metropolitan area — including Ridgeland, Madison, Brandon, Pearl, and Clinton — sits at the geographic crossroads of Mississippi's major soil types. The western edge of the metro hits the loess bluffs with their silty, erosion-prone soil. Eastern suburbs sit on the red clay hills of the Central Plateau, with heavy clay soil similar to but slightly lighter than the Delta's buckshot. Zone 8a conditions give Jackson a growing season that runs from mid-March through early November, with summer temperatures regularly exceeding 95 degrees and humidity that makes fungal disease a constant concern. Bermuda dominates sun-exposed lawns, while centipede fills shaded and low-maintenance lots. Zoysia is increasingly popular in Jackson's established neighborhoods where mature hardwoods create significant shade challenges that bermuda can't handle.
- Jackson's loess-influenced soil erodes aggressively on slopes — establish bermuda or zoysia on graded slopes immediately and use erosion blankets during establishment
- Brown patch fungus is endemic in Jackson's humid summers — avoid evening irrigation and apply preventive fungicide (azoxystrobin) in May before humidity peaks
Gulf Coast (Gulfport / Biloxi / Ocean Springs)
Mississippi's Gulf Coast from Bay St. Louis through Gulfport, Biloxi, and Pascagoula has a subtropical climate that's in a league of its own. Zone 8b to 9a conditions mean winters are mild (hard freezes are rare events, not annual certainties), the growing season stretches nearly year-round, and the humidity is oppressive from May through October. The soil is predominantly deep sand and sandy loam — well-drained, acidic (pH 5.0 to 6.0), and nutrient-poor. It drains so fast that fertilizer leaches through before grass can use it, which is why slow-release fertilizers and split applications are essential here. Salt spray from the Gulf reaches several miles inland during storms and gradually salinizes coastal soils. Hurricane storm surge is the catastrophic threat — Katrina deposited saltwater and debris across every lawn within a mile of the coast, and recovery took years.
- Sandy coastal soil needs split fertilizer applications — three to four light applications per season rather than two heavy ones, because nutrients leach through sand before roots can absorb them
- After any tropical storm or hurricane, flush salt-affected lawns with 2 to 3 inches of fresh water daily for a week to push salt below the root zone
North Mississippi (Tupelo / Oxford / Corinth)
North Mississippi from Tupelo and Oxford up through Corinth and Holly Springs is the state's transition into more temperate conditions. Zone 7b to 8a means winters are colder than the rest of the state — low single digits are possible, and hard freezes lasting several days occur most years. The soil is a mix of clay loam and sandy clay in the hills, with richer bottomland soils along the Tombigbee River corridor. This is the part of Mississippi where bermuda's cold tolerance gets tested, and homeowners who don't pick cold-hardy varieties pay the price with winterkill and slow spring green-up. The slightly cooler climate also means tall fescue is marginally viable in heavily shaded areas, making this a soft transition zone. Oxford's Ole Miss campus and Tupelo's older residential neighborhoods both showcase beautiful bermuda lawns, proof that the species thrives here when managed properly.
- North Mississippi's Zone 7b winters demand cold-hardy bermuda varieties — common bermuda thins badly after hard winters, and Yukon bermuda offers significantly better cold tolerance
- Apply winterizer fertilizer (high potassium, 10-5-15) in early October to help bermuda harden off before the first freeze, which typically hits north Mississippi by late November
