From the median frost dates of the NOAA stations assigned to the 10 ZIP codes in zone 2a, and the timing recommended by Cooperative Extension guides for broccoli.

Dates before the last frost assume the soil has thawed and is dry enough to work: a squeezed handful crumbles instead of sticking. After a late or wet spring, wait for that even if the date has passed.

Frost risk in zone 2a

Zones are based on winter cold, not on frost dates, so the last spring frost varies a lot within a zone. Across zone 2a, the typical last frost ranges from about May 13 in the earliest tenth of ZIP codes to May 25 in the latest tenth, and the first fall frost from September 1 to September 13. For a typical place in the zone:

  • May 8Risky: a later frost happens in 9 years out of 10
  • May 19Typical: frost after this date in half of years
  • June 1Safe: a later frost only 1 year in 10
