Questions

When should I plant cauliflower in Utah?

In Salt Lake City, plant out from March 17 to March 31. Across Utah the window opens between February 28 and May 19, depending on the local last frost.

How is this date worked out?

Start seeds indoors 8–10 weeks before the last frost; plant out up to 2 weeks before the last frost; sow again for fall 10–12 weeks before the first frost. Frost dates are NOAA 1991–2020 averages for the weather station nearest each city.
