Radicchio in Zone 2a & 2b
Cichorium intybus
When to plant radicchio in zone 2b
Zones 2a and 2b share the same average frost dates in our data, so this page covers both.
Method: Either: Start indoors for an earlier harvest, or direct-sow outside for less fuss. Radicchio tolerates either.
| Start indoors | Apr 22–Apr 29 |
|---|---|
| Direct sow / transplant outside | May 20–May 27 |
| Estimated harvest | Aug 3–Aug 10 (~75 days after planting) |
Spacing: 2 per square foot (square-foot-gardening spacing). Mature height: 0.5-1.5 ft.
Radicchio is a chicory grown for a tight, wine-red head with white ribs and a bitterness that people either build meals around or quietly compost. Grilled or roasted, the bitterness turns sweet. Raw in a salad in July, it can be close to inedible.
How radicchio fits zone 2's season
Zone 2b's frost-free window runs about 104 days, from May 20 to September 1. Radicchio needs about 75 days from sowing to first harvest.
