Growing Turnip in Spokane

Spokane's Zone 6b inland Pacific Northwest climate differs significantly from Seattle's — less rain, more sun, and more extreme temperature swings. The Palouse region's continental climate means hot, dry summers ideal for tomatoes and peppers (a welcome contrast to rainy western Washington). The frost-free window of about 171 days is adequate for a wide range of crops when warm-season starts begin indoors in late March.

In Spokane (last frost around April 22), turnip can go out around March — approximately 6 weeks before the last expected frost, making it an early-season opportunity.

Turnip thrives between 40°F and 65°F. It tolerates temperatures as low as 28°F, making it a candidate for early spring planting before the last frost date. Expect 35–60 days from transplant to first harvest. Fast cool-season root. Both roots and greens are edible.
