When to Plant Cabbage in Connecticut

Growing Cabbage in Connecticut: Complete Guide

Cabbage (Brassica oleracea var. capitata) is a warm-season crop that needs a head start indoors before Connecticut's last frost. Depending on your zone, Connecticut gardeners start seeds indoors between February 22, 2027 (Zone 7b) and March 9, 2027 (Zone 6a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Connecticut stretches across 4 USDA hardiness zones (6a, 6b, 7a, 7b), 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 70 days to maturity, Cabbage needs the indoor head start that Connecticut'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.
