When to plant zucchini in Texas

Texas spans USDA hardiness zones 6a-10a. Average last spring frost: varies by region. This calendar gives you the indoor start, transplant, and direct-sow dates for Cucurbita pepo.

Texas planting dates for zucchini

Dates for Texas vary significantly by region. Use the average frost date lookup for your specific ZIP code, then apply the standard offsets: start zucchini indoors 3 weeks before your last frost; transplant 1 weeks after last frost; direct sow 1 weeks after last frost.

Why these dates

Zucchini germinates fast in warm soil. Squash vine borer is the main killer in the eastern US - row covers until flowering, then hand-pick adults in late June.

The dates above are anchored to Texas's average last spring frost date (which varies by region within the state), with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
