Tomatoes are warm-season crops that need 6-8 hours of direct sun and soil temperatures above 60F to thrive. Indeterminate varieties need staking or caging. Determinate varieties stay bushier and ripen all at once.
The dates above are anchored to South Carolina's average last spring frost date of 04-05, with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
