Questions

When should I plant brussels sprouts in Washington?

In Seattle, plant out from February 22 to March 8. Across Washington the window opens between February 16 and April 24, depending on the local last frost.

How is this date worked out?

Start seeds indoors 6–8 weeks before the last frost; plant out up to 2 weeks before the last frost; sow again for fall 14–16 weeks before the first frost. Frost dates are NOAA 1991–2020 averages for the weather station nearest each city.
