Heat-Tolerant Vegetables for the Deep South

title: "Heat-Tolerant Vegetables for the Deep South"

The Deep South — Alabama, Georgia, Mississippi, Louisiana, and South Carolina — presents vegetable gardeners with a paradox: the climate is warm enough for two and sometimes three growing seasons, yet summer heat intense enough to shut down fruiting crops for most of June through August. Per Clemson Cooperative Extension, South Carolina gardeners experience 80–100 days above 90°F annually, with July average highs of 92–95°F across the Piedmont and Coastal Plain. Georgia and Alabama gardeners face similar conditions.

The opportunity is real. Per University of Georgia Cooperative Extension, Georgia gardeners can grow crops in spring (March–June), fall (August–November), and winter (November–February in zones 8–9). The constraint is understanding which crops belong in which season and accepting that July in Georgia is not tomato season — it is okra season.
