When to Plant Cabbage in Maine

Growing Cabbage in Maine: Complete Guide

Cabbage (Brassica oleracea var. capitata) is a warm-season crop that needs a head start indoors before Maine's last frost. Depending on your zone, Maine gardeners start seeds indoors between February 27, 2027 (Zone 7a) and April 8, 2027 (Zone 3b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Maine stretches across 8 USDA hardiness zones (3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a), planting windows can shift by as much as six to eight 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 70 days to maturity, Cabbage needs the indoor head start that Maine's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Cabbage requires full sun to partial shade and regular (1-1.5 inches/week) moisture. In the Northeast, cool summers and moderate humidity can slow warm-season crops, so choose a sheltered, south-facing spot to maximise heat.
