When to Plant Watermelon in Georgia
Published: April 24, 2026
Georgia gardeners in Zone 7b have a 38-week growing season for watermelon (March 1 to November 22). The moderate climate supports a full warm-season crop plus a single main harvest. This guide gives exact dates for Georgia based on your local frost calendar.
Watermelon Planting Dates for Georgia
| Start seeds indoors | February 8–15 |
| Last frost (average) | March 1 |
| Transplant outdoors | March 15–25 |
| Direct sow outdoors | March 15–25 |
| Expect first harvest | May 24 – June 13 |
| First fall frost (average) | November 22 |
Dates above assume Zone 7b, the most common zone in Georgia. Gardeners in cooler Atlanta (Zone 7b) plant 1–2 weeks later; warmer Savannah (Zone 9a) can plant 1–2 weeks earlier.
⚠ Plant watermelon 2 weeks after last frost when soil exceeds 65°F. Needs 70–90 frost-free days. Direct sow in warm climates; start indoors in Zone 4–5.
Growing Watermelon in Georgia's Climate
Georgia's moderate Zone 7b climate is well-suited to watermelon 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 watermelon harvest significantly in Georgia. 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 watermelon pests to watch for in Georgia include Cucumber Beetle and Squash Bug. The first line of defense is companion planting: Corn 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.

Watermelon Growing Tips for Georgia Gardeners
- •Plant on a warm, sunny slope or use black plastic mulch to maintain soil temperature above 70°F all season.
- •Give each plant 6 feet of space — watermelon vines sprawl and need room to run.
- •Georgia's moderate climate supports succession planting — sow new transplants or seeds every 3 weeks during spring to extend the harvest window into fall.
- •Water deeply twice a week during fruit development; reduce watering as melons near ripeness to concentrate sugars.
Companion Planting for Watermelon in Georgia
In Georgia's moderate climate, planting watermelon with Corn and Radish helps deter pests and improve soil. Avoid planting near Cucumber and Potato, which inhibit watermelon growth through root chemistry or shared pest pressure. See the full watermelon companion planting guide for the complete list.
