When to Plant Watermelon in Mississippi

The ultimate summer treat. Watermelons need heat, space, and patience — but the payoff is pure joy.

The Short Answer

In Mississippi, watermelon 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 watermelon are frost-sensitive, start seeds indoors 3 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 Watermelon in Mississippi

Watermelon in Mississippi's Climate

Watermelon is a natural fit for your warm climate. The long, hot season produces the sweetest, largest melons. Start transplants early for a long harvest. Texas, Georgia, and the Carolinas are premier watermelon territory. Deep watering during fruit development and reducing water near harvest concentrates sweetness.

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 70°F before planting watermelon outside.

Mississippi Climate & Growing Season

Long growing season. Hot, humid summers. Mild winters. Two-season gardening possible. Watermelon 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 watermelon — transplant timing shifts by several weeks across the state.

Growing Tips

Black plastic mulch warms soil faster. Check ripeness by looking for a yellow ground spot and listening for a hollow thump.
