Vegetable & Herb Horticulture in North America: Southeast & Gulf Coast

The Gulf Coast vegetable year is split by summer heat. Tomatoes and peppers are a spring crop; collards, kale and roots are an autumn-to-winter crop, and midsummer is for cover crops and soil.

Practice in this climate

Practitioners plant by soil temperature, not the calendar: warm-season crops go out after the last frost and stop setting fruit when nights stay above 24°C. Fall planting starts in September, with brassicas and greens following the heat down. Raised beds, drip irrigation and nematode-resistant cultivars are standard.

Watch outDo not fight the summer: a cover crop of cowpea or sorghum is more productive than a struggling tomato.

The year here

SeasonWhat to do
AutumnPlant brassicas, greens and roots; save seed from spring crops.
WinterHarvest, cover on frost nights, and improve beds with compost.
SpringPlant tomatoes and peppers after the last frost.
SummerSow a cover crop, solarise beds, and rest the soil.

Constraints

  • Heat and humidity drive fungal disease; airflow, spacing and resistant cultivars matter more than spraying.
  • Heavy clay and a high water table cause root rot; raise beds and plant on the shoulder.
  • Hurricane wind and salt prune the coast; choose flexible, salt-tolerant trees away from the house.
