Warm Winter / Frost-Free Areas

Zones: 9b–12

March can be peak garden season in these warm-winter zones. It is also a "pivot" month for gardening in much of the warmer parts of these zones. The risk of frost is over. Cool-season crops are in and doing well. March & April are the times to start transitioning from cool-season greens to heat-loving summer crops.

Indoors (fresh harvests):

  • Microgreens: peas, broccoli, sunflowers, arugula.
  • Sprouts: alfalfa, broccoli, radish, mung
  • Herbs & greens under lights: chives, parsley, mint

Transplants to move outdoors (weather permitting - harden first): pepper, tomato, eggplant, melons, basil

Crops that can be directly sown outdoors in March: cucumber, squash, beans, corn, melons, okra, plus replanting for many greens and root crops

Cover crops: buckwheat, cow peas, sorghum

Tip: A SoCal zone 10 can be different from a Florida zone 10. Consider checking with your state Extension Service office for more specific recommendations and guidelines.

Use your USDA zone as a guide. Microclimates matter—coastal/urban spots run warmer; high elevation runs colder.
