When to Plant Peas in Kentucky
Published: April 24, 2026
Kentucky gardeners in Zone 6b have a 33-week growing season for pea (March 22 to November 10). Kentucky's spring and fall windows both work well for pea — some gardeners plant both successions for a long harvest. This guide gives exact dates for Kentucky based on your local frost calendar.
Pea Planting Dates for Kentucky
| Start seeds indoors | Year-round |
| Last frost (average) | March 22 |
| Direct sow outdoors | February 15–25 |
| Expect first harvest | April 11 – April 26 |
| Fall crop start | September 1–11 |
| Fall harvest | October 26 |
| First fall frost (average) | November 10 |
Dates above assume Zone 6b, the most common zone in Kentucky. Gardeners in cooler Louisville (Zone 6b) plant 1–2 weeks later; warmer Bowling Green (Zone 7a) 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 Kentucky's Climate
Kentucky's moderate Zone 6b climate is well-suited to pea with minimal special accommodation. The standard transplant calendar works as written, and harvest windows line up with what seed packets recommend without adjustment.
Succession planting extends your pea harvest significantly in Kentucky. A second planting 3 to 4 weeks after the first gives you a backup in case of pest pressure and extends the total harvest window into early fall.
Common pea pests to watch for in Kentucky 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 Kentucky 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.
- •Kentucky's moderate climate supports succession planting — sow new transplants or seeds every 3 weeks during spring to extend the harvest window into fall.
- •Sow every 2 weeks through early spring for a continuous 6-week harvest window.
