When to Plant Peas in Mississippi
Published: April 24, 2026
Mississippi gardeners in Zone 8a enjoy an extended 41-week growing season for pea. Cool-season crops like pea do best in fall, winter, and early spring in Mississippi — the hot summers bolt these plants before they can be harvested. This guide gives exact dates for Mississippi based on your local frost calendar.
Pea Planting Dates for Mississippi
| Start seeds indoors | Year-round |
| Last frost (average) | February 15 |
| Direct sow outdoors | January 11–21 |
| Expect first harvest | March 7 – March 22 |
| Fall crop start | September 22–October 2 |
| Fall harvest | November 16 |
| First fall frost (average) | December 1 |
Dates above assume Zone 8a, the most common zone in Mississippi. Gardeners in cooler Jackson (Zone 8a) plant 1–2 weeks later; warmer Gulfport (Zone 8b) can plant 1–2 weeks earlier.
⚠ Plant peas 4–6 weeks before last frost — one of the first vegetables of spring. Tolerate light frost. Also plant in late summer for a fall harvest.
Growing Peas in Mississippi's Climate
Mississippi's warm Zone 8a climate makes pea a fall, winter, and early spring crop rather than a summer one. The cool-season window runs roughly October through April in Mississippi — plant outside this window and the pea will bolt (send up a flower stalk and turn bitter) before it produces a harvestable crop.
Succession planting stretches the pea harvest window. Sow small amounts every two weeks from October through February — you will have staggered harvests rather than a single wave to process all at once. Bolt-resistant varieties extend the usable window an extra three to four weeks into warming weather.
Common pea pests to watch for in Mississippi include Pea Aphid and Powdery Mildew. The first line of defense is companion planting: Carrot and Radish planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.

Pea Growing Tips for Mississippi Gardeners
- •Soak pea seeds overnight before planting to speed germination in cool soil.
- •Install a 4–6 foot trellis at planting time — peas climb from day one and produce more per square foot when supported.
- •Mississippi's cool-season pea plants best in October, November, and December for winter and early spring harvest. Spring plantings bolt before producing a harvestable crop.
- •Sow every 2 weeks through early spring for a continuous 6-week harvest window.
