Hawaii planting dates for tomatoes
Dates for Hawaii vary significantly by region. Use the average frost date lookup for your specific ZIP code, then apply the standard offsets: start tomatoes indoors 8 weeks before your last frost; transplant 2 weeks after last frost;
Why these dates
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 Hawaii's average last spring frost date of no-frost, with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
