Turnip in Zone 2a & 2b
Brassica rapa
Yes, turnip grows in zones 2a and 2b. Plant it outside Apr 29–May 6. For a fall crop, plant out Jun 29–Jul 13.
When to plant turnip in zone 2b
Zones 2a and 2b share the same average frost dates, so this page covers both.
Method: Direct sow: Direct-sow outside. It doesn't transplant well, or doesn't need the extra time indoors.
| Window | Spring window |
|---|---|
| Start indoors | Not typically started indoors |
| Direct sow / transplant outside | Apr 29–May 6 |
| Estimated harvest | Jun 18–Jun 25 (~50 days after direct-sowing) |
| Window | Fall window |
|---|---|
| Start indoors | Not typically started indoors |
| Direct sow / transplant outside | Jun 29–Jul 13 |
| Estimated harvest | Aug 18–Sep 1 (~50 days after direct-sowing) |
Spacing: 9 per square foot (square-foot-gardening spacing). Mature height: 1-1.5 ft.
Fall window: the last sowing date is the average first frost minus days to maturity, the method in Purdue Extension's fall garden guide, which lists turnip for late-summer planting.
Plant alongside it in zone 2b
These go outside within two weeks of turnip in zone 2b, so one planting day can cover them.

Turnips are an underused fast crop: direct-sown, no transplanting fuss, and ready to eat in under two months. They're an easy way to fill a bed gap between slower-growing neighbors.
How turnip fits zone 2's season
Zone 2b's frost-free window runs about 104 days, from May 20 to September 1. Turnip needs about 50 days from sowing to first harvest.

Zone 2 sows before zone 3 here, which looks wrong and is not. USDA zones rank winter cold, not season length, and zone 2 is mostly interior Alaska, where hard winters come with warm summers. More on what a zone measures.
