When to Plant Radicchio in Nebraska

Growing Radicchio in Nebraska: Complete Guide

Radicchio (Cichorium intybus) is a warm-season crop that needs a head start indoors before Nebraska's last frost. Most Nebraska gardeners begin seeds indoors around Sunday, March 28, 2027 and move transplants outside around Sunday, April 11, 2027, after the risk of frost has passed.

Because Nebraska stretches across 3 USDA hardiness zones (5a, 5b, 6a), 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 Nebraska'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. Great Plains gardens face strong winds and variable moisture — windbreaks and drip irrigation help significantly.
