When to Plant Cauliflower in Arkansas

Growing Cauliflower in Arkansas: Complete Guide

Cauliflower (Brassica oleracea var. botrytis) 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 1, 2027 (Zone 8b) and February 27, 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 75 days to maturity, Cauliflower 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.

Cauliflower requires full sun (6 hours) and regular (1-1.5 inches/week) moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
