When to plant radishes in Salem, OR
Plant radishes from seed, directly in the garden in Salem, Mar 1 – Apr 26. For a fall harvest, plant again Sep 3–17.
Why these dates
Salem's typical last spring frost is April 3. As a cool-season crop that handles light frost, this crop doesn't need to wait for that date. In the west-side valleys, though, the soil usually isn't ready to work until about March 1.
West-side valleys. The Willamette Valley, Puget Sound and southern Oregon valleys. Long frost-free seasons, but soil stays cold and wet into May, so warm crops wait for warm soil, not just the last frost.
