Direct sowing and transplanting windows that fall in March, most urgent first. Windows are one-to-two-week bands around the ideal date.

Indoor sowings for transplants later. Six to eight weeks under lights is typical for tomatoes and peppers; onions and leeks need longer.

Keep sowing (succession)

Repeat sowings of crops already in the ground, for a steady harvest instead of a glut.

• Pea: sow again on Mar 9 and Mar 21
• Spinach: sow again on Mar 9 and Mar 21
• Mache (Corn Salad): sow again on Mar 13 and Mar 27

Last-frost month: March garden jobs in Mississippi

1. The average last frost is March 20. Hardy crops can go out now - green onion / scallion, arugula, beet, fava bean (broad bean) - but hold tender ones like tomatoes, peppers and squash until after that date.
2. Start hardening off indoor seedlings 7-10 days before they go out: a few hours of outdoor shade first, building up to full sun and nights outside.
3. Keep row cover or old sheets handy and watch the 10-day forecast - a clear, still night after a warm spell is the classic late-frost setup.
4. Soil temperature matters as much as the calendar: most warm-season seed rots below about 60°F. Check the frost dates guide for how the Mississippi average is worked out.
