SCIENTIFIC NAME

Cichorium intybus

CULTURE

For North American production, these varieties are vast improvements over older types, but are still not perfectly uniform or completely predictable. Although bred for specific seasons, it is still best to trial more than one variety, using succession plantings to determine which one suits your conditions. Radicchio is hardy and can be planted as early as the soil can be worked. It is a cool weather crop and grows best at temperatures of 60-65ยฐF (15.5-18.3ยฐC). Careful variety selection is important for hot weather plantings. Sow every 3 weeks for a continuous supply of fresh radicchio.

THERMAL DORMANCY

Radicchio seed can enter thermal dormancy when exposed to high temperatures above 77ยฐF (25ยฐC). Optimum germination results at soil temperatures of 60-68ยฐF (15.5-20ยฐC).

TRANSPLANTING

Sow in flats, 4 seeds/in., or in 3/4" plug trays, barely covering seeds with fine vermiculite, 3-4 weeks before transplanting outdoors. Shade the flats on sunny, warm days if necessary to keep the soil surface cool, below 75ยฐF (24ยฐC), until germination. If sowing into flats, transplant 1-2" apart into flats, pots, or cell-type containers about 2 weeks later. Harden seedlings by reducing water and temperature for 2-3 days before planting outdoors. Properly hardened transplants can survive temperatures as low as 20ยฐF (-6ยฐC). Transplant 8" apart in rows 18" apart. Transplant shallowly so that the base of the plant will be slightly above the soil to discourage bottom rot.

DIRECT SEEDING

Seeds will germinate from 41-85ยฐF (5-29ยฐC), but the highest germination percentage will occur around 75ยฐF (24ยฐC), depending on the variety and seed lot. Sow seeds 1" apart, rows 12-18" apart. Cover seed lightly, about 1/8", and firm soil gently. Thin to 8" apart; thinnings may be transplanted. Dry soil must be watered to ensure coolness and moisture, and for uniform germination.

NOTE

Radicchio grows best in cool or mild weather, i.e. fall, winter, and spring. Summer crops can be successful if nights are cool (below 60ยฐF/16ยฐC).

DAYS TO MATURITY

From date of cool-weather, spring transplanting. Subtract 10-14 days for late spring or early summer, warm-weather transplanting. Add about 14 days for direct seeding.

AVG. DIRECT SEEDING RATE

1M/220', 5M/1,100', 10M/2,200', 131M/acre at 3 seeds every 8" in rows 18" apart.

TRANSPLANTS

Avg. 500 plants/M (2 seeds per cell thinned to one seedling).
