When to plant Rutabaga
Computed from land-grant Extension planting-window rules (cited below), localized to real ZIP-level median frost dates, not a single national guess. These are national-generic rules by hardiness class; individual state Extension offices layer their own regional adjustment on top (earlier in the Deep South, later in the Upper Midwest). Enter your ZIP for your own dates, or read the four representative locations below.
Planting windows and crop timing here are computed from USDA/NOAA climate data and the university extension sources cited below, not a site visit or soil test. Treat this as a starting point: local conditions vary, and a local nursery or extension office can advise on your exact site. See our full Disclaimer.

Zones 10-13 (hot, frost rare or absent) (Loxahatchee, FL): Frost is rare here (about 359 frost-free days a year); most years see little or no hard freeze. This is a hardy crop. In climates like this one, hardy and semi-hardy crops typically go in during the cooler months (fall through late winter), not on a frost-relative schedule.
Rutabaga carries an inferred, not a directly sourced, hardiness classification on this page. No source held for rutabaga states its tier explicitly; this page classifies it hardy by direct analogy to turnip, the same genus, which Colorado State and Purdue both classify hardy, and Clemson Cooperative Extension's combined Turnips & Rutabagas factsheet (HGIC 1324) treats the two as agronomically similar cool-season crops.
The two-to-four-week-before-frost window shown is likewise borrowed from turnip's Colorado State-sourced rule by the same analogy, and is flagged here as inferred rather than a figure any source states for rutabaga by name. Days to maturity, 70 to 80 days, is NC State Extension's figure (AG-756-01), the one explicit number found for this crop specifically.
No minimum soil temperature and no fall-specific weeks-before-frost figure are held for rutabaga, even though Clemson and Virginia Cooperative Extension both confirm fall culture with their own calendar dates. Rather than infer a second number the way the spring window was inferred, that field is left blank. Rutabaga runs mostly as a fall crop in Virginia's own zone data, so in a cold-winter climate the fall planting is worth weighting more heavily than the inferred spring window; a mild-winter climate has more room across both.
Rutabaga is seed-only at the nursery, sold as seed rather than as transplants, the same as turnip.
Frost hardiness
Hardy. Tolerates hard frost. Can go in the ground before the last frost date.
Days to maturity
70–80
Sourcing notes
No source in this set gives rutabaga's hardiness tier explicitly. Classified hardy by direct analogy to turnip (same genus, CSU/PURDUE both hardy) - Clemson's combined turnips-and-rutabagas factsheet treats the two as agronomically similar cool-season crops, and VCE shows rutabaga as fall-only in most zones (consistent with a hardy crop grown for a cool-finish harvest). The -4,-2wk window is likewise borrowed from turnip's CSU-sourced rule by analogy, flagged as inferred rather than directly stated for rutabaga. DTM (70-80 days) is NCSU's figure, the only explicit number found. No min soil temp or fall-specific weeks-before-frost figure was found despite Clemson/VCE confirming fall culture with calendar dates.
