Published: April 24, 2026
New York gardeners in Zone 6a have a 31-week growing season for turnip (March 30 to November 1). New York's spring and fall windows both work well for turnip — some gardeners plant both successions for a long harvest. This guide gives exact dates for New York based on your local frost calendar.
Turnip Planting Dates for New York
| Start seeds indoors | Year-round |
| Last frost (average) | March 30 |
| Direct sow outdoors | March 9–19 |
| Expect first harvest | April 13 – May 8 |
| Fall crop start | September 6–16 |

Dates above assume Zone 6a, the most common zone in New York. Gardeners in cooler Buffalo (Zone 5b) plant 1–2 weeks later; warmer New York (Zone 6a) can plant 1–2 weeks earlier.
⚠ Direct sow turnips 2–4 weeks before last frost for spring crop. Best planted in late summer (6–8 weeks before first fall frost) for fall harvest — frost sweetens the roots. Fast-growing: some varieties ready in just 35 days.
Growing Turnips in New York's Climate
New York's moderate Zone 6a climate is well-suited to turnip with minimal special accommodation. The standard transplant calendar works as written, and harvest windows line up with what seed packets recommend without adjustment.
Succession planting extends your turnip harvest significantly in New York. A second planting 3 to 4 weeks after the first gives you a backup in case of pest pressure and extends the total harvest window into early fall.
Common turnip pests to watch for in New York include Flea Beetle and Aphid. The first line of defense is companion planting: Pea and Mint planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.
