When to Plant Watermelon in Arkansas

Growing Watermelon in Arkansas: Complete Guide

Watermelon (Citrullus lanatus) is a warm-season crop that needs a head start indoors before Arkansas's last frost. Depending on your zone, Arkansas gardeners start seeds indoors between February 15, 2027 (Zone 8b) and March 13, 2027 (Zone 7a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Arkansas stretches across 4 USDA hardiness zones (7a, 7b, 8a, 8b), 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, Watermelon needs the indoor head start that Arkansas's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Watermelon requires full sun (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.
