When to Plant Zucchini in Mississippi

Growing Zucchini in Mississippi: Complete Guide

Zucchini (Cucurbita pepo) is a warm-season crop that needs a head start indoors before Mississippi's last frost. Depending on your zone, Mississippi gardeners start seeds indoors between January 23, 2027 (Zone 9a) and March 8, 2027 (Zone 7b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Mississippi stretches across 4 USDA hardiness zones (7b, 8a, 8b, 9a), planting windows can shift by as much as two to four weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 50 days to maturity, Zucchini needs the indoor head start that Mississippi's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Zucchini requires full sun (6-8 hours) and regular (1-2 inches/week) moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
