When to Plant Radicchio in Massachusetts

Growing Radicchio in Massachusetts: Complete Guide

Radicchio (Cichorium intybus) is a warm-season crop that needs a head start indoors before Massachusetts's last frost. Depending on your zone, Massachusetts gardeners start seeds indoors between March 13, 2027 (Zone 7a) and March 23, 2027 (Zone 6a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Massachusetts stretches across 3 USDA hardiness zones (6a, 6b, 7a), 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, Radicchio needs the indoor head start that Massachusetts's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Radicchio requires full sun to partial shade and regular (keep moist) moisture. In the Northeast, cool summers and moderate humidity can slow warm-season crops, so choose a sheltered, south-facing spot to maximise heat.
