Warm-Season Vegetable

When to Plant Tomatoes in Mississippi

America's favorite garden vegetable (technically a fruit). Nothing beats a sun-warmed tomato straight off the vine.

The Short Answer

In Mississippi, tomatoes planting dates vary by region. In Northern Mississippi, your average last frost is around Mar 15 - Apr 1, while Southern Mississippi sees its last frost around Feb 15 - Mar 5. Since tomatoes are frost-sensitive, start seeds indoors 6 weeks before your last frost, then transplant outside 2 weeks after frost danger has passed. Rich delta soils in west. Heavy clay in many areas. Sandy in pine belt. Acidic throughout.

Growing Tomatoes in Mississippi

Tomatoes in Mississippi's Climate

Your long growing season gives tomatoes plenty of time, but extreme summer heat above 95°F can cause blossom drop and pause fruit set during the hottest weeks. In the Deep South and Texas, many growers aim for two tomato seasons — spring (transplant early) and fall (start new plants in July). Choose heat-tolerant varieties like Heat Wave, Solar Fire, and Phoenix. Afternoon shade from taller plants can help during the most brutal July-August heat.

Soil Considerations for Mississippi

Rich delta soils in west. Heavy clay in many areas. Sandy in pine belt. Acidic throughout. Make sure soil has warmed to at least 60°F before planting tomatoes outside.

Mississippi Climate & Growing Season

Long growing season. Hot, humid summers. Mild winters. Two-season gardening possible. Tomatoes cannot tolerate any frost, so wait until all frost danger has passed before transplanting outside. Watch local forecasts carefully in spring.

Growing season length varies across Mississippi: Northern Mississippi (7b, 8a) has a last frost around Mar 15 - Apr 1, while Southern Mississippi (8b, 9a) sees frost end around Feb 15 - Mar 5. This difference matters for tomatoes — transplant timing shifts by several weeks across the state.

Growing Tips

Pinch off suckers for indeterminate varieties. Stake or cage for best results. Water at the base, not overhead, to prevent blight.

Companion Planting

Plant tomatoes alongside these companions for better growth:

Basil Carrots Peppers Marigolds

Keep tomatoes away from:

Brassicas Fennel Dill

The Bottom Line

Tomatoes can be grown successfully across Mississippi, but your exact planting dates depend on which region you're in.
