When to Plant Edamame in Mississippi

Growing Edamame in Mississippi: Complete Guide

Edamame (Glycine max) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in Mississippi falls between March 6, 2027 (Zone 9a) and April 19, 2027 (Zone 7b), once soil temperatures are consistently warm enough for germination.

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 80 days to maturity, Edamame fits comfortably within Mississippi's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Edamame 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.
