When to Plant Eggplant in Arkansas
Published: April 24, 2026
Arkansas gardeners in Zone 7a have a 35-week growing season for eggplant (March 15 to November 15). The moderate climate supports a full warm-season crop plus a single main harvest. This guide gives exact dates for Arkansas based on your local frost calendar.
Eggplant Planting Dates for Arkansas
| Start seeds indoors | January 11–18 |
| Last frost (average) | March 15 |
| Transplant outdoors | April 5–15 |
| Expect first harvest | June 9 – June 24 |
| First fall frost (average) | November 15 |
Dates above assume Zone 7a, the most common zone in Arkansas. Gardeners in cooler Little Rock (Zone 7b) plant 1–2 weeks later; warmer Fayetteville (Zone 7a) can plant 1–2 weeks earlier.
⚠ Start eggplant indoors 8–10 weeks before last frost — same timing as peppers. Transplant 2–3 weeks after last frost when soil is above 60°F. Needs heat and full sun. Does not tolerate cold — protect from temps below 50°F.
Growing Eggplant in Arkansas's Climate
Arkansas's moderate Zone 7a climate is well-suited to eggplant 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 eggplant harvest significantly in Arkansas. 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 eggplant pests to watch for in Arkansas include Flea Beetle and Colorado Potato Beetle. The first line of defense is companion planting: Pepper and Bean 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.

Eggplant Growing Tips for Arkansas Gardeners
- •Use a heat mat during germination — eggplant seeds need 24–27°C soil to sprout reliably.
- •Protect transplants from cold spring nights — temperatures below 10°C halt growth for weeks.
- •Arkansas's moderate climate supports succession planting — sow new transplants or seeds every 3 weeks during spring to extend the harvest window into fall.
- •Use stakes or small cages — eggplant stems bend or break under the weight of mature fruit.
Companion Planting for Eggplant in Arkansas
In Arkansas's moderate climate, planting eggplant with Pepper and Bean helps deter pests and improve soil. Avoid planting near Fennel and Brassicas, which inhibit eggplant growth through root chemistry or shared pest pressure. See the full eggplant companion planting guide for the complete list.
