Frost likely Frost possible Frost unlikely Frost is likely until April 27 and fades out by May 23. It is unlikely from then until September 18, and likely again after October 15. The dashed lines are the typical dates, May 10 and September 30.

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.
