Radicchio tastes much better when grown in cold weather. In areas with cool summers radicchio can be treated like lettuce. Plant it 2 to 4 weeks before the last spring frost. Hot weather makes radicchio leaves intensely bitter, so in warm climates it is normally grown as a fall crop. It is started 8 to 12 weeks (depending upon the variety) before the first fall frost. Radicchio thrives in most soil types, but for easy harvesting, a loose, rich, and fairly moist soil is best.
