Frost likely Frost possible Frost unlikely Frost is likely until May 9 and fades out by June 7. It is unlikely from then until September 9, and likely again after October 4. The dashed lines are the typical dates, May 25 and September 22.

Your season is too short for a separate fall planting of cabbage and broccoli: sown late enough to be a fall crop, it wouldn't be ready before the typical first frost. Your spring planting is your harvest.
