Radicchio in Zone 8a & 8b
Cichorium intybus
When to plant radicchio in zone 8b
Zones 8a and 8b 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 | Feb 25–Mar 4 |
|---|---|
| Direct sow / transplant outside | Mar 25–Apr 1 |
| Estimated harvest | Jun 8–Jun 15 (~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 8's season
Zone 8b's frost-free window runs about 230 days, from March 25 to November 10. Radicchio needs about 75 days from sowing to first harvest.
