Lawn timing geography of Mississippi

Across the 94 Mississippi locations with complete 1991–2020 frost normals, the average last spring frost — the anchor for pre-emergent and spring work — ranges from Feb 12 (Biloxi) to Apr 9 (Iuka), a spread of about 8 weeks driven by elevation, latitude, and terrain. The same job can be weeks apart at opposite ends of the state, which is why a state-level date is only a starting point — pick the location nearest your yard and plan from its calendar.

The Mississippi lawn year in one paragraph

The Mississippi lawn year lives in the warm months: pre-emergent in late winter before soil crosses 55°F, establishment and the first feeding after full green-up, aeration in the heat of active growth, and steady mowing all summer. The discipline that separates good southern lawns is the stop date — no nitrogen within 6–8 weeks of first frost, so the lawn hardens off and goes dormant on schedule. Details by task: when to overseed in Mississippi, when to aerate in Mississippi, when to apply crabgrass pre-emergent in Mississippi, and more above.
